No response to jquery ajax submission

Example 1

The code is as follows:	Copy code
$. Ajax ( { Type: "POST ", Url: "/a. php ", Success: function (result ){ // ToDo: } )

When we click submit, no results are returned, so no results are found in the test using the ff browser. Later, we found that the data: "{a: 'A'}" parameter is missing, we only need to modify it.

The code is as follows:	Copy code
$. Ajax ( { Type: "POST ", ContentType: "application/json ", Url: "a. php ", Data: "{a: 'A '}", Success: function (result ){ } )

Ajax submission in jquery. form in E in ie8 does not respond.

I analyzed this problem for several hours and found that I set application/x-javascript, and ie8 won't work anymore, the solution is to set other parameters or not to set them during ajax submission.
