A pop-up window of the web calendar flashes? Efficient debugging skills help you easily modify styles!
When debugging web calendar pop-ups, many developers often encounter the problem of pop-ups disappearing instantly, resulting in the inability to select elements and modify styles in browser developer tools. This article provides a practical tip to help you solve this problem and complete style debugging smoothly.
Problem: After clicking on the web calendar pop-up window, when selecting the target element in the browser console, the pop-up window disappears.
Solution: Cleverly use the setTimeout function and debugger statement to pause code execution before the pop-up window disappears, thereby capturing its DOM structure.
Operation steps:
Open the browser developer tool: Press F12 or right-click on the page and select "Check" or "Check Elements".
Enter and execute the following code in the console:
setTimeout(() => { debugger; }, 2000);
This code will trigger the debugger statement after 2000 milliseconds (2 seconds), causing the browser to enter debug mode and pause execution. This time is enough for you to click to open the calendar pop-up window and debug before it disappears.
Click to open the calendar pop-up window: After the code is executed, immediately click on the calendar icon or element on the web page to open the calendar pop-up window.
Browser pause execution: At the
debuggerstatement, the browser pauses execution. At this time, the calendar pop-up window is still visible.Select elements and modify styles in the Developer Tools: Use the Developer Tools (usually the Elements or Inspector panel), find the DOM element of the calendar pop-up window, and modify its CSS styles as needed.
Adjust the time parameters of
setTimeout: If the 2000 milliseconds time is too long or too short, causing the pop-up window to disappear too fast or the debugging time is insufficient, please try to adjust the number of milliseconds insetTimeoutfunction and try to find the appropriate pause time point many times.
With this method, you can effectively capture the briefly displayed calendar popups and easily modify their styles. Remember, 2000 milliseconds are just an example value and need to be adjusted according to actual conditions.
