When developing with jQuery, sometimes we need to convert a jQuery object into a string. For example, you need to convert form data to a string when making an AJAX request, or you need to print out a jQuery object when printing debugging information. So, how do you convert a jQuery object to a string?

In fact, converting jQuery objects into strings is very simple, and jQuery provides a variety of methods to achieve this function. Below I will introduce you to some of the most commonly used methods.

标题
 
段落1
 
段落2

var str = $('#test').text(); console.log(str); // 输出：标题段落1段落2

Method 2: Use $.fn. html() method

$.fn.html() method can obtain the HTML code of the specified element, including HTML tags and text content.

标题
 
段落1
 
段落2
 

We can use the following code to convert the div element into a string:

var str = $('#test').html(); console.log(str); // 输出： // 
标题
 // 
段落1
 // 
段落2

We can use the following code to convert the form into a string:

var str = $('#myForm').serialize(); console.log(str); // 输出：username=zhangsan&password=123456&gender=male&hobby=movie
