jQuery Load New Window

Use jQuery to open the link in a new window

The following code snippet demonstrates how to use jQuery to open a link in a new window. The code adds events to the anchor tag with the "new-window" class, forcing them to open in a new window.

$(function(){
  $('a.new-window').click(function(){
    window.open(this.href);
    return false;
  });
});

Advanced Example: Opening a link by ID

This code gets the ID of the container div, then gets the hidden url div element, and finally opens it in a new window.

function openblog(blog_id) {
    //alert(blog_id);
    $('#blog-wrap-'+blog_id).hide();
    var blogurl = $('#'+blog_id+'-url').text();
    var location = "http://domainname/index.php?blogurl="+blogurl;
    window.open(location);
}

FAQs on jQuery Loading Window

What is the jQuery load event and how it works?

The jQuery load event is a built-in function that is triggered when a specific element (such as an image or a window) is fully loaded. This event is usually used to execute code after the target element is fully loaded, ensuring that any operation or interaction to the element occurs after it is fully available. The syntax of the load event is: $(selector).load(function). A selector is the HTML element that you want to apply the load event, and a function is the code to execute when the load event occurs.

How to check if jQuery is loaded on my page?

You can check if jQuery is loaded on the page using simple JavaScript code. Examples are as follows:

if (window.jQuery) {
  // jQuery已加载
  alert("jQuery is loaded");
} else {
  // jQuery未加载
  alert("jQuery is not loaded");
}

This code checks whether the jQuery object is available in the global window scope. If available, it means jQuery has been loaded; otherwise, jQuery is not loaded.

What is the difference between jQuery load event and window.onload event?

The jQuery load event and window.onload event both fire when a specific element is fully loaded. However, their main difference is that the jQuery load event can be applied to any element, while the window.onload event only applies to the entire window. In addition, the jQuery load event handles errors more gracefully than the window.onload event.

Why does my jQuery load event not work?

There are many reasons why your jQuery load event may not work. A common reason is that the element you are trying to locate with the load event is undefined or does not exist. Another reason might be that jQuery itself is not loading or is not properly linked to your HTML file. If your jQuery load event does not work, be sure to check for these potential issues.

How to load external content into a div using jQuery load event?

You can use the jQuery load method to load external content into a div. Examples are as follows:

$("#divID").load("external_content.html");

In this example, the contents of the "external_content.html" file will be loaded into a div with ID "divID". Please note that the load method here is different from the load event. The load method is used to load data from the server and put the returned HTML into the selected element.

Can I use multiple jQuery load events on the same page?

Yes, you can use multiple jQuery load events on the same page. Each load event can locate different elements and execute different functions. However, remember that each load event will be fired independently after its target element is fully loaded.

Is the jQuery load event deprecated?

Yes, starting with jQuery 1.8, the load event has been deprecated, replaced by the on method. The on method provides a more powerful and flexible way to attach event handlers to elements. However, for backward compatibility, jQuery still supports load events.

How to replace load event using jQuery on method?

You can attach the load event handler to the element using the jQuery on method. Examples are as follows:

$(function(){
  $('a.new-window').click(function(){
    window.open(this.href);
    return false;
  });
});

In this example, the function is executed when the load event occurs on the selected element.

Can I use the jQuery load event with AJAX?

Yes, you can use the jQuery load event with AJAX to execute the code after the AJAX request is complete and after the content is loaded to the page. However, note that the load event is only triggered for specific elements such as images and not usually for AJAX requests.

What are some common use cases for jQuery load events?

jQuery load event is usually used to execute code after the image or window is fully loaded. For example, you might want to show a loading animation before the image loads, then hide the animation and display the image. Another common use case is to execute code that interacts with the window after the window is fully loaded (such as resizing or scrolling) to ensure the code works properly.
