jQuery's text()
attribute has two versions: text()
and text(val)
. Key points:
- jQuery's
text()
function has two versions:text()
Gets the text content of all matching elements;text(val)
is similar tohtml()
, but escapes HTML.
The alternative to -
text()
is a custom function that preserves line breaks. This function uses theinnerText
attribute (if available), otherwise useinnerHTML
while replacing<br>
withn
and removing all other HTML tags. - jQuery's
text()
function can be used to get or set the text content of one or more elements. It treats HTML tags as plain text and cannot be used to get or set HTML content. For appending text, use the.append()
method instead of.text()
.
jQuery text()
Function
Syntax: .text()
Function: .text()
Gets the text content of all matching elements. Browser Compatibility: text()
Works properly in all browsers we have tested. Basic example: Find the text in the first paragraph (removing HTML), and then set the HTML for the last paragraph to show that it is just the text (the red bold disappears).
jQuery text(val)
Function
Syntax: .text(val)
Function: .text(val)
Similar to .html()
, but escapes HTML (replaces HTML entity with its corresponding HTML entity). Browser Compatibility: text(val)
Works properly in all browsers we have tested. Basic example: Add text to the paragraph (note that the bold tag is escaped).
$("p").text("Some new text.");
jQuery text()
Alternatives to functions
This is a jQuery function that can be used as an alternative to jQuery's .text()
, which preserves line breaks.
(function($){ $.fn.innerText = function(msg) { if (msg) { if (document.body.innerText) { for (var i in this) { this[i].innerText = msg; } } else { for (var i in this) { this[i].innerHTML = this[i].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } return this; } else { if (document.body.innerText) { return this[0].innerText; } else { return this[0].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } }; })(jQuery);

Function FAQ
How to use jQuery text()
function to get the text content of an element?
jQuery text()
Functions are a powerful tool that allows you to get the text content of an element. To do this, you just use the jQuery selector to select the element and call the .text()
method. For example, if you want to get the text content of a paragraph with id "myPara", you can use the following code:
var text = $("#myPara").text();
In this code, $("#myPara")
is the jQuery selector for selecting paragraphs, and .text()
is the way to get text content. The text content is then stored in the variable "text".
Can I use the jQuery text()
function to set the text content of an element?
Yes, you can set the text content of an element using the jQuery text()
function. To do this, you need to pass the new text content as a parameter to the .text()
method. For example, if you want to set the text content of a paragraph with id "myPara" to "Hello, World!", you can use the following code:
$("p").text("Some new text.");
In this code, $("#myPara")
is the jQuery selector for selecting paragraphs, and .text("Hello, World!")
is the method to set the text content.
What happens if I use the jQuery text()
function on multiple elements?
If you use the jQuery text()
function to get the text content of multiple elements, it will return the combined text content of all selected elements. For example, if you have two paragraphs with class "myClass", and you want to get their text content, you can use the following code:
(function($){ $.fn.innerText = function(msg) { if (msg) { if (document.body.innerText) { for (var i in this) { this[i].innerText = msg; } } else { for (var i in this) { this[i].innerHTML = this[i].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } return this; } else { if (document.body.innerText) { return this[0].innerText; } else { return this[0].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } }; })(jQuery);
In this code, $(".myClass")
is the jQuery selector for selecting paragraphs, and .text()
is the way to get text content. The combined text content of the paragraph is then stored in the variable "text".
If you use the jQuery text()
function to set the text content of multiple elements, it will set the text content of all selected elements to the specified text. For example, if you want to set the text content of all paragraphs with class "myClass" to "Hello, World!", you can use the following code:
var text = $("#myPara").text();
In this code, $(".myClass")
is the jQuery selector for selecting paragraphs, and .text("Hello, World!")
is the method to set the text content.
Can I get or set HTML content using the jQuery text()
function?
No, jQuery text()
function cannot be used to get or set HTML content. The .text()
method treats any HTML tag as plain text. If you want to get or set HTML content, you should use the .html()
method instead.
jQuery text()
What is the difference between a function and a jQuery html()
function?
The main difference between jQuery text()
functions and jQuery html()
functions is how they handle HTML tags. The .text()
method treats any HTML tags as plain text, while the .html()
method treats them as HTML. This means that if you use the .text()
method to get the content of an element, it will return text content that does not contain any HTML tags. If you use the .html()
method, it returns HTML content, including any HTML tags.
Can I use the jQuery text()
function with other jQuery methods?
Yes, you can use the jQuery text()
function with other jQuery methods. For example, you can use the .text()
method with the .css()
method to change the text content and style of an element at the same time. Here is an example:
$("p").text("Some new text.");
In this code, $("#myPara")
is the jQuery selector for selecting paragraphs, .text("Hello, World!")
is the way to set text content, and .css("color", "red")
is the way to change the text color to red.
How to append text to an element using jQuery text()
function?
If you want to append text to an element using jQuery, you should use the .append()
method instead of the .text()
method. The .text()
method replaces the existing text content with the new text, and the .append()
method adds the new text to the end of the existing text content. Here is an example:
(function($){ $.fn.innerText = function(msg) { if (msg) { if (document.body.innerText) { for (var i in this) { this[i].innerText = msg; } } else { for (var i in this) { this[i].innerHTML = this[i].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } return this; } else { if (document.body.innerText) { return this[0].innerText; } else { return this[0].innerHTML.replace(/<br>/gi,"n").replace(/(]+)>)/gi, ""); } } }; })(jQuery);
In this code, $("#myPara")
is the jQuery selector for selecting paragraphs, and .append(" Hello, World!")
is the method to append the text "Hello, World!" to the end of the existing text content.
Can I remove text from an element using the jQuery text()
function?
If you want to use jQuery to remove all text from an element, you can use the .text()
method and pass the empty string as an argument. This will replace the existing text content with an empty string, effectively deleting the text. Here is an example:
var text = $("#myPara").text();
In this code, $("#myPara")
is the jQuery selector for selecting paragraphs, and .text("")
is the method to delete text.
If you want to remove specific text from an element, you need to use the .replaceWith()
method or use the .html()
method that contains a function that replaces specific text with an empty string.
jQuery text()
What is the return type of the function?
jQuery text()
The return type of the function depends on how it is used. If used to get the text content of an element, it returns a string containing the text content. If used to set the text content of an element, it returns a jQuery object, allowing method chained calls.
Can I use the jQuery text()
function with non-text elements?
Yes, you can use the jQuery text()
function with non-text elements. If you use the .text()
method to get text content for non-text elements, it will return text content for any text nodes within the element. If you set text content for non-text elements using the .text()
method, it replaces any text nodes within the element with the new text.
The above is the detailed content of jQuery .text() function. For more information, please follow other related articles on the PHP Chinese website!

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

Python is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.
