This article is to share with you about how to submit Chinese garbled codes by JQuery ajaxSubmit. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Most people use

JQuery (form) .ajaxSubmit ({url: "ajaxsub.aspx?abc=test", type: "post", dataType: "json", success: data})

Analysis: the AJAX submission of JQuery encodes the data to be submitted and uses encodeURIComponent to process the data in js. Therefore, whether it is Firefox or IE, the submitted data is consistent and is UTF-8-encoded data.

Look at Header and find that there are differences in Content-Type in Entity

In Firefox, Content-Type specifies that the character set is utf-8.

However, there is no character set specification in IE.

Obviously, by default, the character encoding submitted asynchronously by AJAX should be consistent with the page itself, that is, the server uses gb2312 to decode the data (but the data has been encoded by UTF-8 before it is submitted) if the charset specified by the server is not found. This is the root cause of garbled code under IE, while under Firefox, the browser adds the display specification of charset when submitting AJAX data. Causes the server to use UTF-8 to decode the data (decode it correctly).

Referring to the description of the AJAX tool function of JQuery, it is found that there is a parameter that specifies content-type in options.

So specify the encoding type at the time of submission

ContentType: "application/x-www-form-urlencoded; charset=utf-8"

That is, as follows

JQuery (form) .ajaxSubmit ({url: "ajaxsub.aspx?abc=test", type: "post", dataType: "json", contentType: "application/x-www-form-urlencoded; charset=utf-8", success: data}); thank you for reading!
