Sharing of tab production technology for jquery plug-in development
This article mainly introduces the tab production of jquery plug-in development in detail. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
In jquery, common plug-in development methods include:
One is to extend a method for the $ function itself. This is a static extension (also called a class extension). This kind of plug-in is usually Tool method,
There is also one that extends on the prototype object $.fn. The developed plug-in is used on the dom element
1. Class level extension
$.showMsg = function(){
alert('hello,welcome to study jquery plugin dev');
}
// $.showMsg();Be careful to introduce the jquery library in advance. In the above example, a method showMsg is added to the $function, then it can be called with $.showMsg()
$.showName = function(){
console.log( 'ghostwu' );
}
$.showName();This kind of plug-in is relatively rare and is generally used to develop tool methods, such as $.trim, $.isArray(), etc. in jquery
2. Expand the function on $.fn.
This kind of plug-in is used on elements. For example, if I extend a function and click a button, the value of the current button will be displayed.
$.fn.showValue = function(){
return $(this).val();
}
$(function(){
$("input").click(function(){
// alert($(this).showMsg());
alert($(this).showMsg());
});
});
<input type="button" value="点我">Add a showValue method on $.fn to return the value of the current element. After obtaining the page input element and binding the event, you can call this method to display the button The value "click me" is commonly used in actual plug-in development. Next, we will use this extension mechanism to develop a simple tab plug-in:
