关于格式化jason显示在页面上

json-viewer

下载 这个js 的插件 代码

在页面上加载 

如果是动态页面，记得另外写一个调用的js 方法

如下

页面加载3秒后才调用相应的数据

      
        window.onload = function() {
      
      
          var inputfromText;
      
      
        
          

      
      
          setTimeout(function() {
      
      
            var iframes = document.getElementsByTagName('iframe');
      
      
            for (var i = 0; i < iframes.length; i++) {
      
      
              var iframeDoc = iframes[i].contentDocument || iframes[i].contentWindow.document;
      
      
              var iframeJquery = iframes[i].contentWindow.$;
