About the solution to jQuery's AJAX incompatibility with IE

When using jQuery's AJAX: get method to detect whether data exists, you will find that IE will be incompatible.

When using the AJAX:post method, the correct results can appear when using Chrome/FireFox/IE, but when using the AJAX:get method, IE cannot return the correct results.

Could it be that the data exceeds the length limit of the get method? This is impossible. I only transferred a little bit of data in total. exclude.

Some netizens on the Internet said that it is a problem with IE cache. Just add a random number after the request data, such as adding the time number new Date().getTime().

I have added random numbers in the previous code, and using "Math.random()" does not work. Is it more reliable to use time?

Then try changing it to getting the time. After adding "new Date().getTime()" to the parameter, it still doesn't work after repeated testing. It's really puzzling! This error is also eliminated.

After repeatedly checking the manual, I found that the requested data format still has a JSON format, such as {foo:["bar1", "bar2"]}, and then I wrote it in this format, and it really returned the correct query results. I really didn't know IE still had this requirement. (End)

Previous format:

type: "get",
data: "bid="+my_bid+"&name_cn="+name_cn+"&timeStamp="+new Date().getTime(),

Improved format:

type: "get",
data: {'bid':my_bid,'name_cn':name_cn,'timeStamp':new Date().getTime()},

is described in the jQuery manual:

data Object,String

Send to server The data. Will be automatically converted to request string format. Appended to the URL in GET requests.

See the processData option description to disable this automatic conversion. Must be in Key/Value format.

If it is an array, jQuery will automatically correspond to the same name for different values. For example, {foo:["bar1", "bar2"]} is converted to "&foo=bar1&foo=bar2".

Code snippet:

var siteUrl="http://blog.sina.com.cn/cnwyt"; 
jQuery.ajax({
type: "get",
url: siteUrl+"cosmetics/product/ajax_check?",
//data: "bid="+my_bid+"&name_cn="+name_cn+"&timeStamp=" + new Date().getTime(),
data: {'bid':my_bid,'name_cn':name_cn,'timeStamp':new Date().getTime()},
dataType: 'json',
error: function (err) { alert('网络故障,请与管理员联系！') },
success: function (message) {
if(message!=false){
//ture的代码
}else{
//false的代码
}
});
