jquery converts numbers to json

In front-end development, it is often necessary to convert numbers into JSON objects. In jQuery, we can use the parseJSON() method to convert numbers into JSON objects.

The parseJSON() method is a method in the jQuery library, used to convert JSON-formatted strings into JSON objects. When we need to convert a number into a JSON object, we put the number into a string and then use the parseJSON() method to convert it into a JSON object.

Here is a sample code:

var num = 123;
var jsonString = '{"num":' + num + '}';
var jsonObj = jQuery.parseJSON(jsonString);

console.log(jsonObj.num);

In this example, we put the number 123 into a JSON formatted string. Then, use the parseJSON() method to convert it to a JSON object. Finally, we get the number from the JSON object and print it to the console.

At the same time, in actual development, we can also put the number into a character array, and then use the eval() function or JSON.stringify() function to convert it into a JSON object.

The following is a sample code using the eval() function:

var num = 123;
var jsonString = '["num":' + num + ']';
var jsonObj = eval('(' + jsonString + ')');

console.log(jsonObj.num);

In this example, we use the eval() function to convert a number into a JSON object. Among them, we put the numbers into a character array. Finally, we also get the number from the JSON object and output it to the console.

To summarize, jQuery provides the parseJSON() method for converting JSON-formatted strings into JSON objects. When we need to convert a number into a JSON object, we can put the number into a character string or array, and then use the eval() function or parseJSON() method to convert it into a JSON object.
