s = "Height of visible area of ​​rn web page:" document.body .clientHeight;
s = "rnThe height of the visible area of ​​the webpage:" "document.body.offsetWeight" (including the width of the edge)"; Including the width of the edge)";

Regular matching

Copy code The code is as follows:

match Chinese characters Regular expression: [u4e00-u9fa5]
Matching double-byte characters (including Chinese characters): [^x00-xff]
Regular expression matching blank lines: n[s| ]*r
Regular expression matching HTML tags: /.*1>|/
Regular expression matching leading and trailing spaces: (^ s*)|(s*$) (trim function like vbscript)
Regular expression matching email address: w ([- .]w )*@w ([-.]w )*.w ( [-.]w )*
Regular expression matching URL: http://([w-] .) [w-] (/[w- ./?%&=]*)?
The following is an example:
Use regular expressions to limit the input content of the text box in the web form:
Use regular expressions to limit only Chinese input: onkeyup="value=value.replace(/[^u4E00-u9FA5 ]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^u4E00-u9FA5]/g,''))"
1. Use regular expressions to limit the input of only full-width characters: onkeyup="value=value.replace(/[^uFF00-uFFFF]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData(' text').replace(/[^uFF00-uFFFF]/g,''))"
2. Use regular expressions to limit the input of numbers: onkeyup="value=value.replace(/[^d] /g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^d]/g,''))"
3. Use regular expressions Only numbers and English can be entered: onkeyup="value=value.replace(/[W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace (/[^d]/g,''))"
