Solution to pareseerror error in JQuery 1.3.2 or above_jquery

It feels very strange. It was fine a while ago, but why is it suddenly reporting an error now? The program didn't move at all. So I started tracking and analyzing the content requested and returned. . . The final judgment is that jquery

does not recognize that the returned content is in json format. The content returned at that time was:

Copy code The code is as follows:

{'keylist':[
{'tid':'13',"sumnum':'1'},{'tid':'21','sumnum':'1'}
]}

After careful inspection, no problem was found. The characters of the return stream have been set to utf-8, and the content was detected with ff. ff can also recognize it as json format, but at this time, a "pareseerror" error was still reported. >Looking at the code, I suddenly discovered that the currently returned content is enclosed in English single quotes. I vaguely remembered that the strictest way of writing should be English double quotes, so I immediately modified the system's underlying library (c#)

’s json data generation method, all changed to English double quotes, the content returned after the change is as follows:

Copy code The code is as follows :

{"keylist":[

{"tid":"13","sumnum":"1"},{"tid":"21","sumnum": "1"}
]}


The result was put into the test server and the problem was solved! I really&*^#%@$@

Summary: Think about it carefully. A few days ago, the latest version of jquery was used to replace the old version in the group purchase system for some reasons. I did not expect this situation at the time. Later, I found information from the Internet and found that jquery has adopted stricter parsing of json since version 1.3.x. method, so the data must be written consistent with international standards.
