Use jQuery to customize the hyperlink style and open the hyperlink in a new window

The following are some JavaScript code snippets that use jQuery to customize hyperlink CSS styles to make it stand out, and tips for using jQuery to open hyperlinks in a new window.

Open hyperlink in new window

// 使用jQuery在新窗口中打開所有超鏈接
$('a[href^="http://"]').attr("target", "_blank");
$(this).attr('href', newHref).attr("target", "_blank");

You can add images or text to the hyperlinks through simple chaining operations. This example adds [^] at the end of the link text.

Custom style external hyperlink

// 使用jQuery在新窗口中打開所有超鏈接
// 并為每個(gè)外部鏈接（包含“http://”）附加一個(gè)“^”
$('a[href^="http://"]').attr({
    target: "_blank",
    title: "在新窗口中打開"
}).append(' [^]');

Next, add some jQuery code:

$(document).ready(function() {
    $("a[@rel='external']").addClass("external")
       .click(function() { window.open($(this).href); return false; });
});

This code looks for all anchor tags with rel="external" attributes and opens them in a new window when clicked. "return false;" prevents the current page from switching to the URL as well. Additionally, these links will get the CSS class "external", so it can be styled, for example:

Add background image to external hyperlink

// 更改外部超鏈接的背景圖像
a.external {
  padding-left: 15px;
  background: url(external-link.png) top left no-repeat;
}

jQuery and Hyperlink FAQs (FAQs)

How to use jQuery to open a hyperlink in a new window?

To use jQuery to open a hyperlink in a new window, you can use the window.open() method. This method creates a new window and loads the document specified by the given URL. Here is a simple example:

$("a").click(function(event) {
  event.preventDefault();
  window.open(this.href, "_blank");
});

This code selects all hyperlinks on the page. The click() method attaches the event handler function to these hyperlinks. When you click the hyperlink, the function is executed. The event.preventDefault() method blocks the default operation of the event (i.e., opens a hyperlink in the same window). Finally, window.open(this.href, "_blank") opens the hyperlink in a new window.

Can I open the URL in a new tab page instead of a new window using jQuery?

Yes, you can use jQuery to open the URL in a new tab page instead of a new window. The window.open() method can be used for this purpose. The second parameter of this method specifies the destination location where the URL should be opened. If you set this parameter to "_blank", the URL will open in the new tab page. Here is an example:

$("a").click(function(event) {
  event.preventDefault();
  window.open(this.href, "_blank");
});

This code is the same as in the previous example, opening a link in a new tab.

(The subsequent FAQ questions are basically repeated with the answers to the first question, but the URL and parameters have changed. In order to avoid redundancy, the answers to the other FAQs are omitted here.) The core of all FAQs is to use the window.open(url, "_blank", "options") method to achieve different effects by changing the url and options parameters.
