How to send raw text with xmlhttp request?

ajax, javascript, xmlhttprequest

Solution

Yes it can be done by modifying `headerRequest` and `data` like this:

var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");

if(typeof(FormData) == 'undefined'){
    var boundary = '---------------------------' + (new Date).getTime(),//boundary is used to specify the encapsulation boundary of a parameter
        data = "--" + boundary + "\r\n";
        data += 'Content-Disposition: form-data; name="data"\r\n\r\n';//here we specify the name of the parameter name (data) sent to the server which can be retrieved by $_POST['data']
        data += string + "\r\n";
        data += "--" + boundary + "--\r\n";
    xhr.open( 'post', 'writeCode.php', true );
    xhr.setRequestHeader('Content-Type', 'multipart/form-data; boundary=' + boundary);
}else{
    var data = new FormData();
    data.append("data", string);
    xhr.open( 'post', 'writeCode.php', true );
}
xhr.send(data);

Problem

I'm trying to send a `textarea` field's text to a PHP file using ajax, the text contains HTML characters and should not be encoded. Using `FormData` it works perfectly however it's not supported in ie 9 and older versions! I tried to send the data as `string` by setting the `requestHeader` to `text/plain;charset=UTF-8;` or `multipart/form-data` but it didn't work! the code i'm using is: ``` var string = '<td clas="tdClass">some text<?php echo $contents; ?></td>'; var data = new FormData(); data.append("data" , string); var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP"); xhr.open( 'post', '/path/to/php', true ); xhr.send(data); ``` what's an alternative way to do this in IE 9?
