JSthis scope and the problem of too long GET transfer value _ javascript skills

The IEURL parameter in the IE7 browser is too long, causing an error in HTTPStatus122. For this scope problem, the corresponding solution is as follows. If you are interested, refer, I hope it will be helpful to you. When developing projects, the front-end will encounter two hidden problems.

Problem 1: The ie url parameter in the IE7 browser is too long, causing an HTTP Status 122 error.
Cause: there is no problem in IE6.8, but the get parameter is too long in IE7. google says, "Don't use the GET method in Ajax Apps, if you can void it, because IE7 craps out with more than 2032 characters in a get string"

Solution:
Change the jsonp get data method of the original project to the conventional post data method.

Question 2. this scope Problem
Cause: if this is not a large window object in the object, this indicates the ajax object of the current domain name.

Solution:

The Code is as follows:

Var test = {};
Test. getflash = 2;
Test. test = function (){
Alert (this. getflash); // 2
$. Ajax ({
Type: "POST ",
Url: "some. php ",
Data: "name = John & location = Boston ",
Success: function (msg ){
Alert (this. getflash); // equals to undefine
}
});
}

Solution:

The Code is as follows:

Test. test = function (){
Var thisValue = this;
Alert (thisValue. getflash); // 2
$. Ajax ({
Type: "POST ",
Url: "some. php ",
Data: "name = John & location = Boston ",
Success: function (msg ){
Alert (thisValue. getflash); // 2
}
});
}
