Detailed explanation of how to use the lightweight JavaScript template engine mustache.js
We will explain in detail how to use Mustache.js lightweight JavaScript template engine.
Simple example
function show(t) { $("#content").html(t); } var view = { title: 'YZF', cacl: function () { return 6 + 4; } }; $("#content").html(Mustache.render("{{title}} spends {{cacl}}", view));
You can clearly see the syntax of the Mustache template, just use {{ and }} Just include it and put the name of the object in it.
It can also be seen from this example that if the specified attribute is a function, the content in the function will not be output, but the function will be executed first, and then the returned result will be displayed.
Not escaping HTML tags
var view = { name: "YZF", company: "<b>ninesoft</b>" }; show(Mustache.render("{{name}} <br /> {{company}} <br />{{{company}}}<br/>{{&company}}", view));
Through this example, we can see that Mustache will encode the html tags in the value by default. Escaped, but sometimes we don't need it.
So here we can use {{{ and }}} to include, or {{ and }} to include, then Mustache will not escape the html tags inside.
Bind the value of sub-attribute
var view = { "name": { first: "Y", second: "zf" }, "age": 21 }; show(Mustache.render("{{name.first}}{{name.second}} age is {{age}}", view));
I believe that when seeing the first example, someone will think about whether it can Binding subproperties, if you bother to read it. So congratulations, now is the way to solve your needs, just use the sub-property through .
Conditional selection of whether to render the specified part
var view = { person: false }; show(Mustache.render("eff{{#person}}abc{{/person}}", view));
There are always problems. If we still need to be able to decide whether to render a certain part based on the value we give part, then this problem can be solved now. Of course, it should be noted that it is not just false that will cause the specified part not to be rendered.
null, empty array, 0, and empty string are equally valid. The syntax is relatively simple, just use {{#key}} ... {{/key}} to control the content in the middle.
Loop output
var view = { stooges: [ { "name": "Moe" }, { "name": "Larry" }, { "name": "Curly" } ] }; show(Mustache.render("{{#stooges}}{{name}}<br />{{/stooges}}", view));
Just learn the above method, you will solve most of the problems, but you will still have troubles The place is loop output. If you write one by one, I believe it will be very irritating. Of course, Mustache will not let us down. It also gives a way to loop output. Here is an array composed of objects. If we output is an array, you need to use {{.}} instead of {{name}}.
Loop output is the value returned after processing by the specified function
var view = { "beatles": [ { "firstname": "Johh", "lastname": "Lennon" }, { "firstname": "Paul", "lastname": "McCartney" } ], "name": function () { return this.firstname + this.lastname; } }; show(Mustache.render("{{#beatles}}{{name}}<br />{{/beatles}}", view));
The loop output is available, but we still want to process it later. Then this completely meets your needs, because Mustache will pass the values in the array to your function and output the value returned by your function. Here we can see that the outermost layer is an array. As long as a function is used inside, the outer array will be passed in as a parameter of this function.
Custom function
var view = { "name": "Tater", "bold": function () { return function (text, render) { return render(text) + "<br />"; } } } show(Mustache.render("{{#bold}}{{name}}{{/bold}}", view));
We all used variables as sections above, so now we use functions as sections, will What effect does it have.
It will call the function returned by our function, taking the original string in the middle of the section as the first parameter, and the default interpreter as the second parameter, then we can process it ourselves.
Antonym Section
var view = { "repos": [] }; show(Mustache.render("{{#repos}}{{.}}{{/repos}}{{^repos}}no repos{{/repos}}", view));
We also use sections above, but we can only choose whether to output a certain part. So here we make up for it.
If we use {{^ and }} to define a section, then this part will only be displayed when the value inside is empty, null, empty array, or empty string. Then we can achieve the effect of if else.
Partial Templates
var view = { names: [ { "name": "y" }, { "name": "z" }, { "name": "f" } ] }; var base = "<h2 id="Names">Names</h2>{{#names}}{{>user}}{{/names}}"; var name = "<b>{{name}}</b>"; show(Mustache.render(base, view, { user: name }));
Although Mustache saves a lot of time, we have defined many templates, but they cannot interact with each other. Nested use will also cause cumbersomeness.
So here we also introduce how to define some templates for use in other templates. The way to use other templates here is just {{>templetename}}.
The biggest difference is that the Mustache.render method has a third parameter.
Precompiled template
Mustache.parse(template); //其他代码 Mustache.render(template,view);
Templates have advantages and disadvantages. It just takes time to compile the template, so if we know that we will use a certain template, we can pre-compile the template for later use.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
