javascript - 如何将代码添加到 <script> </script> 中

Question

我正在尝试将代码添加到脚本中，但它不起作用

    var script= document.createElement('script');
    script.type= 'text/javascript';
    script.textContent = var Module = {
        TOTAL_MEMORY: 536870912,
        errorhandler: null, 
        compatibilitycheck: null,
        dataUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.data",
        codeUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.js",
        memUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.mem",
    };
    script.async = true;
    document.body.appendChild(script);

如何添加才能变成这样？

这边；转义双引号(用 " 括起内部内容)，反之亦然。另一种方法是使用数组使代码可读，并使用 .join() 连接它们

    var script= document.createElement('script');
    script.type= 'text/javascript';
    script.textContent = 'var Module = { TOTAL_MEMORY: 536870912, errorhandler: null, compatibilitycheck: null, dataUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.data", codeUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.js", memUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.mem", };';
    script.async = true;
    document.body.appendChild(script);

使用数组:

var script= document.createElement('script');
    
    scriptContent = ['var Module = {',
        'TOTAL_MEMORY: 536870912,',
        'errorhandler: null,',
        'compatibilitycheck: null,',
        'dataUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.data",',
        'codeUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.js",',
        'memUrl: "Release/Arctopia_Path_Monopoly_v1.1.1GL.mem",',
    '};',
    'console.log(Module)'].join("");

    script.type= 'text/javascript';
    script.textContent = scriptContent;
    script.async = true;
    document.body.appendChild(script);
