This article describes how to intercept and cut strings in JavaScript. Common javascript operation string functions include split, join, concat, charAt, charCodeAt, slice, substring, and substr. For more information about coders, see. The string cutting and truncation are usually not used in many cases, and the scores are relatively small. Therefore, you can perform self-check on your own. Be prepared.
Since all of the previous tests were conducted in a demo, we apologize for any errors. Some o
Winform file filter and winform file Filter
In the. net Framework, Microsoft encapsulates an OpenFileDialog dialog box for opening files. This dialog box contains a Filter attribute that can Filter files. This attribute can be used to Filter the files we need.

Today, I accidentally found a bug in Windows while working on icons. I downloaded an icon and changed it to 1. ico. Then I thought it was inappropriate and dragged it to the recycle bin. Then, a new icon is named 1.ico. A wonderful moment has happened. After the new icon is renamed, the icon on the desktop is dragged to the recycle bin. At first, I thought it was wrong. After many experiments, I confirmed t

For more information, see: CSS Sprites: image slicing's kiss of deathI have seen abuse of this technique. It is a good idea to merge multiple background images into one to reduce HTTP calls. But remember that this large image cannot be too

Detailed description of JS truncation string functions and js truncation Functions
I. Functions: split ()
Function: uses a specified separator to split a string and store it in an array.
Example:
Str = "jpg | bmp | gif | ico | png"; arr = theString. split ("|"); // arr is an array containing character values "jpg", "bmp", "gif", "ico", and "png"
Ii. function: John ()
Function: combines an array into a stri
smaller value as the starting position, and the length of the truncated string is the difference between a smaller value and a smaller value.Substr ()The first parameter indicates the start position, and the second parameter indicates the truncation length.PS: the string starts from 0.Example:
