Example of setting text values in jquery (setting text box DIV form values) _ jquery-js tutorial

This article describes how to set the content of jquery. The following example shows how to set the content through the text (), html (), and val () methods. For more information, see. Jquery settings-Text (), html (), and val ()

We will use three identical methods in the previous chapter to set the content:

Text ()-set or return the text content of the selected Element
Html ()-set or return the content of the selected element (including HTML tags)
Val ()-set or return the value of a form field

The following example shows how to set content through the text (), html (), and val () methods:

Instance

The Code is as follows:

$ ("# Btn1"). click (function (){
$ ("# Test1"). text ("Hello world! ");
});
$ ("# Btn2"). click (function (){
$ ("# Test2" 2.16.html ("Hello world!");
});
$ ("# Btn3"). click (function (){
$ ("# Test3"). val ("Dolly Duck ");
});

Text (), html (), and val () callback Functions

The preceding three jQuery methods are text (), html (), and val (), which also have callback functions. The callback function consists of two parameters: the subscript of the current element in the list of selected elements and the original (old) value. Then return the string you want to use with the new value of the function.

The following example demonstrates text () and html () with callback functions ():

Instance

The Code is as follows:

$ ("# Btn1"). click (function (){
$ ("# Test1"). text (function (I, origText ){
Return "Old text:" + origText + "New text: Hello world!
(Index: "+ I + ")";
});
});

$ ("# Btn2"). click (function (){
$ ("# Test2" functions .html (function (I, origText ){
Return "Old html:" + origText + "New html: HelloWorld!
(Index: "+ I + ")";
});
});
