JSON-在Internet Explorer 8中无法使用 [英] JSON - Not working in Internet Explorer 8

问题描述

我尝试了一些修复工作，没有任何帮助.

I tried few thing to fix, Nothing helped.

在服务器端脚本中，

 $array['content'] = "test";
 echo json_encode($array);

这在javascript中工作.但是

This is working in javascript. But

 $array['content'] = "<p>test</p>";
 echo json_encode($array);

不起作用.如果我添加任何html标记，则无法正常工作. 但是他们都使用Firefox和Chrome.

Not working. If i add any html tag, it is not working. But they all are working in firefox and chrome.

这是处理返回值的js.

This is the js handling the return value.

 function showResponse(responseText)  {
     $('.form_result').html(responseText.formData);
      alert(responseText.formData);
 }

 function submitButton1() {

    var options = {
        beforeSubmit:  showRequest,  // pre-submit callback
        success:       showResponse,  // post-submit callback
        dataType: 'json',
        cache: false
    };

    // bind form using 'ajaxForm'
    $('#form').ajaxSubmit(options);
 }

     header("Cache-Control: no-cache, must-revalidate");
header("Expires: 0"); 

在php文件中添加了以上两行.

Added the above two lines in php file.

 <meta http-equiv="X-UA-Compatible" content="IE=8" />

在处理js的html文件中添加了上述内容.还是没用.

Added the above in html file which handling the js. Still no use.

可能是什么问题? 此外，我在IE中看不到任何错误或警告.

What could be the problem? additionally, i dont see any error or warning in IE.

推荐答案

Internet Explorer 8在jQuery使用的XMLHttpRequest对象中不支持CORS. ie8使用XDomainRequest对象

Internet Explorer 8 doesn't support CORS in the XMLHttpRequest object which jQuery is using ie8 uses XDomainRequest object

jQuery默认不支持XDomainRequest.

jQuery doesn't support XDomainRequest by default.

选中此更新可用于Internet Explorer 8中的本机JSON功能
