jquery dynamic settings div

As web pages become more complex, front-end development becomes more and more important. jQuery, as a feature-rich JavaScript library, is widely used in web development. In jQuery, dynamically setting divs is one of the common operations. This article will introduce how to use jQuery to dynamically set divs.

1. Create div element

In jQuery, you can create a div element through the following code:

var div = $("<div></div>");

At this time, jQuery will create an empty div element. When creating, you can also add some attributes:

var div = $("<div></div>", {
  "class": "myDiv",
  "id": "myId"
});

This creates a div element with class myDiv and id myId. More attributes can be added in JSON form.

2. Set the content of the div element

The content of the div element can be set through the text() and html() functions. The text() function is used to set the text content of the div, as shown below:

var div = $("<div></div>");
div.text("This is my div.");

The above code will create a div element with the text "This is my div."

html() function is used to set the HTML content of the div element:

var div = $("<div></div>");
div.html("
This is my div.
");

The above code will create a div element containing a paragraph element.

3. Set the div element style

You can set the style of the div element through the css() function. The css() function accepts a JSON object, including several style attributes and corresponding values, as shown below:

var div = $("<div></div>");
div.css({
  "color": "red",
  "background-color": "yellow"
});

The above code will create a div element with color red and background-color yellow.

4. Operation div elements

You can operate div elements through various jQuery methods, such as adding, deleting, moving, hiding, showing, etc. Here are some common methods.

• Add elements

You can add one element to another element through the appendTo() function:

var div1 = $("<div></div>");
var div2 = $("<div></div>");
div2.appendTo(div1);

The above code will create two divs element and add div2 as a child element of div1.

• Delete element

You can delete an element through the remove() function:

var div = $("<div></div>");
div.remove();

The above code will create a div element and delete it.

• Moving elements

Through the appendTo() and prependTo() functions, one element can be moved to another element:

var div1 = $("<div></div>");
var div2 = $("<div></div>");
div2.appendTo(div1); // div2 移动到 div1 中

var div1 = $("<div></div>");
var div2 = $("<div></div>");
div2.prependTo(div1); // div2 移动到 div1 前面

• Hide element

An element can be hidden through the hide() function:

var div = $("<div></div>");
div.hide();

The above code will create a div element and hide it.

• Display element

You can display an element through the show() function:

var div = $("<div></div>");
div.hide();
div.show();

The above code will create a div element and hide it, Then show it again.

The above are some common div element operation methods. There are many other methods. For details, please refer to jQuery official documentation.
