Set Timeout for jQuery AJAX Requests
The given code snippet shows an AJAX request using jQuery, but sometimes the success function does not reliably trigger. To address this, a timeout can be set to automatically handle errors if the request does not complete within the specified time.
Solution:
To set a timeout for an AJAX request, use the timeout option in the $.ajax method. This option specifies the time in milliseconds before the request is considered a timeout. If the request takes longer than the specified time, the error function will be triggered with a "timeout" status.
$.ajax({
url: "test.html",
error: function(){
// Will fire when timeout is reached or other error occurs
},
success: function(){
// Do something
},
timeout: 3000 // Sets timeout to 3 seconds
});
By setting the timeout option, the AJAX request will no longer freeze the execution indefinitely if the server is down or unresponsive. The error function can then be used to handle the timeout and display an error message or take other appropriate actions.
Additionally, the error function can receive the textStatus parameter, which contains the type of error that occurred. If the timeout was reached, textStatus will be set to "timeout".

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
