Triggering File Input with jQuery
When attempting to initiate an upload box using jQuery, you may encounter difficulties if the input field is hidden or invisible. This hurdle stems from a security restriction aimed at preventing unauthorized file uploads.
To circumvent this challenge, one effective method involves positioning the file input field outside the visible area of the page. By setting its position to absolute and adjusting its top attribute by an appropriate amount, you can make the field accessible to JavaScript but conceal it from the user's view. This trick allows the file input to be triggered successfully using the trigger('click') method.
For a practical demonstration, refer to the provided JSFiddle link: http://jsfiddle.net/DSARd/1/. While this approach can be considered a workaround, it offers a reliable solution for triggering file inputs that are otherwise restricted by security measures.

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.
