jquery a link cannot be clicked

In our daily web page production, there are often situations where some a links are not clickable, and this situation is often because there are some problems with our front-end code, causing the links to fail to jump normally. Through this article, we will describe the relevant knowledge of jquery to help everyone solve this type of problem.

1. Reasons why links cannot be clicked

When it comes to links that cannot be clicked, we need to consider the following reasons:

1. Error in link address
   When writing link code, we need to ensure that the link address we write is correct, otherwise we will not be able to jump to the correct page or website.
2. Coding issues
   In the web page code, there are often some problems that cause the link to be unclickable, such as: there are some grammatical errors, conflicts, etc. in the code.
3. CSS Problem
   Sometimes the link is not clickable due to CSS style problems. For example: the CSS style sets the text color inside the a tag to be the same as the background color, resulting in the clickable link being unable to be seen.

2. Related knowledge of jquery

In order to solve the problem that a link cannot be clicked, we can use jquery to handle it. Next, we will introduce some basic jquery knowledge so that everyone can use it better.

1. jQuery library
   jQuery is an efficient, streamlined and feature-rich JavaScript library. It sends Ajax requests, handles events, and shields browser differences, allowing users to quickly and easily complete various interactive operations on the website.
2. jQuery Common Methods
   jQuery has a large number of methods, among which commonly used methods include selectors, event binding, inserting content, modifying styles, animation effects, etc. These aspects are introduced below.

a. Selector
jQuery provides a variety of selectors that allow us to quickly select page elements. For example:

• Select the element by the element name: "$('p')"
• Select the element by the element ID: "$('#p1')"
• Select elements by element class name: "$('.myClass')"

b. Event binding
Event binding can associate web page elements with JavaScript functions, so that when When the user interacts with a web page element, the corresponding JavaScript function is called. For example:

• Click event: "$('p').click(function(){})"
• Mouse move event: "$('p'). mouseover(function(){})"
• Mouse out event: "$('p').mouseout(function(){})"

c. Insert content
We can use jQuery to insert content into web elements. For example:

• Insert text content at the end of the element: "$('p').append('text')"
• Insert text content in front of the element: "$(' p').before('text')"
• Insert text content after the element: "$('p').after('text')"

d. Modify styles
jQuery can modify styles by adding class names, modifying inline styles, or external style sheets. For example:

• Add class name: "$('p').addClass('myClass')"
• Modify element style attributes: "$('p').css ('color', 'red')"
• Modify external style sheet: "$('link').attr('href','new.css')"

e. Animation effects
jQuery can enhance the page interactive experience by adding some simple animation effects. For example:

• Fade out element: "$('p').fadeOut('slow')"
• Fade in element: "$('p').fadeIn( 'slow')"
• Sliding to display elements: "$('p').slideDown('slow')"
• Sliding to hide elements: "$('p').slideUp( 'slow')"

3. Example solution

Now that we have understood the relevant knowledge of jquery, let us use an example to better understand how to solve the link Not clickable issue.

In web page code, we often encounter the following situation: a div is nested inside the a tag, and when the a tag is clicked, the link cannot jump. At this time, we can use the following code to solve this problem:

$('a').click(function(e) {
    e.stopPropagation();
    window.location = $(this).attr('href');
    return false;
});

The function of this code is:

1. Prevent events from bubbling, that is, prevent elements inside a link from also bubbling Respond to events.
2. Get the href attribute of a link and let the link jump to the URL.
3. Block the default event of the link, that is, prevent the a tag from jumping and returning to the original web page.

4. Summary

No matter when and where, we will encounter the problem that a link is not clickable. In the above example, we explained how to use jquery to solve this problem. Problem is solved.

I hope it will be helpful to everyone's front-end web development work.
