Jqueryajax cannot parse json objects. Cause and solution of InvalidJSON error _ jquery

We know that the json object caused by InvalidJSON error cannot be parsed. Generally, the syntax of the json string returned by the server is incorrect. In this case, we only need to carefully check the json to solve the problem. Next let's talk about the problems encountered recently when using the $. ajax () method in jquery 1.4 to parse json objects.

The Json object is:

The Code is as follows:

[{Name: 'Sale of second-hand houses ', infoCount: 0, pageUrl:'/ershoufang '}, {name: 'Buy of second-hand houses', infoCount: 0, pageUrl: '/qiugou'}, {name: 'second-hand house fit', infoCount: 0, pageUrl:'/esfzhuangxiu '}, {name: 'second-hand recycling', infoCount: 0, pageUrl: '/huishou'}, {name: 'Used motorcycle', infoCount: 0, pageUrl: '/motor'}, {name: 'Used car purchase', infoCount: 0, pageUrl: '/ershoucheqg'}, {name: 'second-hand car transfer', infoCount: 9, pageUrl:'/ershoe e '}, {name: 'second-hand market', infoCount: 0, pageUrl: '/ershoushichang'}]

I wonder if you have found any problems with this json object. This method is correct in js scripts and versions earlier than jquery 1.4. In versions 1.3 and earlier, jQuery parses json objects using the javascript eval method. In section 1.4, jQuery uses a more rigorous method to parse json. All content must use double quotation marks.

As shown in jQuery. parseJSON (json), parseJSON is interpreted as follows:

Accepts a JSON string and returns the parsed object.

Inputting a malformed JSON string throws an exception. For example, the following are malformed JSON strings:
{Test: 1} (test is not surrounded by double quotation marks)
{'Test': 1} (using single quotes instead of double quotes)

In addition, if you do not input anything, or an empty string, null, or undefined, parseJSON will return null.
