Converts a json string to a json object. During data transmission, json is transmitted in the form of text, that is, strings, while JS operates on JSON objects. Therefore, mutual conversion between JSON objects and JSON strings is
scripts), which can easily cause system security problems. So you can use some third-party client script libraries that circumvent eval (), such as JSON in JavaScript, which provides a script library of no more than 3k.The second parsing method: Using the Function object to complete, its typical application is in jquery in the Ajax method of success and so on the return data of the parsing

When I called the PHP function that returned the array value in JS a few days ago, I did not know how to read the returned PHP array data in JS. So I thought of converting the PHP array into a JSON string first, then, get the returned value in JS and convert it to an object using the eval function of Js. to read data. How to implement it?

the data type obtained asynchronously by jQuery-json object and string, we will introduce the Processing Methods of the obtained results in two ways.1. For the JSON string returned by the server, if jQuery asynchronous requests do not provide a type description or are accepted as strings, an object processing is required. The method is not too troublesome, is to put this string in eval () for execution onc
Suppose we have obtained a Java object on the server side, and now we are considering how to convert this Java object into a string that complies with the JSON syntax. Of course, we can write a set of algorithms to implement this conversion, but it is troublesome, especially when the object has many attributes or the attribute Nesting is deep, it is more troublesome.
In practice, we can use a ready-made too

The form form has a serialize () method. The ability to serialize the values of the form, but this method of jquery provides a way to serialize the data into a form similar to the following:A=1b=2c=3d=4jquery does not provide a way to serialize form data to JSON. So we need to encapsulate it ourselves. The following gives the code and test examples, first write a JS file:$.ajaxsetup ({ contentType: "application/x-www-form-urlencoded; Charset=utf-8
