Change image path through jquery

With the continuous development of websites, the demand for dynamic effects is also getting higher and higher. As a fast, simple and convenient JavaScript library, jQuery greatly simplifies the development process of front-end pages. This article will introduce how to use jQuery to achieve the effect of changing the Change Change image path through jquery path through jquery path.

1. Requirements Analysis

When we need multiple sets of different skins or themes, it will undoubtedly be very cumbersome if we have to manually modify the paths of all Change Change image path through jquery path through jquerys every time we change the skin. matter. Therefore, we need a more convenient way to change the path of the Change Change image path through jquery path through jquery.

2. Solution design

1. Add a class attribute to the Change Change image path through jquery path through jquery whose path needs to be changed, such as "change-path".

<img  src="img/1.jpg" class="change-path" / alt="Change image path through jquery" >

2. Get these img tags through jQuery and replace their paths.

$('.change-path').each(function() {
    var oldSrc = $(this).attr('src'); //获取原图片路径
    var newSrc = 'newPath/' + oldSrc.substring(oldSrc.lastIndexOf('/') + 1); //构造新图片路径，这里假设新路径为“newPath/”
    $(this).attr('src', newSrc); //替换图片路径
});

3. Code Implementation

Next we will use a simple example to demonstrate how to change the Change Change image path through jquery path through jquery path through jQuery.

1. Preparation

Before this, we need to prepare some pictures. As shown in the figure below:

2. Implementation code

Add the following code in the HTML file:

    
    
    


    
Change Image Path

    <img  src="img/1.jpg" class="change-path" / alt="Change image path through jquery" >
    
    

    <script>
        $('.change-path').each(function() {
            var oldSrc = $(this).attr('src');
            var newSrc = 'newPath/' + oldSrc.substring(oldSrc.lastIndexOf('/') + 1);
            $(this).attr('src', newSrc);
        });
    </script>

In this code, We first introduced the jQuery library. Then, we used the $(".change-path") selector to get all img tags with the "change-path" class attribute, and then used the .each() method to iterate through these tags. When traversing each tag, we obtain the original src attribute value of each tag through the .attr() method and assign it to the variable oldSrc. Then, we modify oldSrc according to needs and get newSrc. Finally, we assign the modified value to the original src attribute through the .attr() method.

3. Execution effect

After running this code, we can see the following effect:

You can see that all pictures The paths have been modified to "newPath/1.jpg", "newPath/2.jpg" and "newPath/3.jpg", which meets our needs.

4. Summary

This article introduces how to change the Change Change image path through jquery path through jquery path through jQuery. Through this method, we can easily modify all pictures that need to change the path, making our development work more efficient and simple. Of course, jQuery can also be used to implement more other dynamic effects, and readers can learn and use them according to their own needs.
