    //Regular match

    Matching regular expressions for Chinese characters: [\U4E00-\U9FA5]
    Match Double-byte characters (including Chinese characters): [^\x00-\xff]
    A regular expression that matches a blank row: \n[\s|] *\r
    Regular expression matching HTML tags:/< (. *) >.*<\/\1>|< (. *) \/>/
    Matching a regular expression with a trailing space: (^\s*) | (\s*$) (Trim function like VBScript)
    Regular expression matching an email address: \w+ ([-+.] \w+) *@\w+ ([-.] \w+) *\.\w+ ([-.] \w+) *
    A regular expression that matches URL URLs: http://([\w-]+\.) +[\w-]+ (/[\w-/?%&=]*)?
    Here is an example:
    Use regular expressions to restrict the entry of text boxes in a Web page's form:
    The regular expression limit can only be entered in Chinese: onkeyup= "value=value.replace (/[^\u4e00-\u9fa5]/g,") "Onbeforepaste=" Clipboarddata.setdata (' Text ', Clipboarddata.getdata (' text '). Replace (/[^\u4e00-\u9fa5]/g, ') "
    1. Only full-width characters can be entered with regular expression restrictions: onkeyup= "Value=value.replace (/[^\uff00-\uffff]/g,") "Onbeforepaste=" Clipboarddata.setdata (' Text ', Clipboarddata.getdata (' text '). Replace (/[^\uff00-\uffff]/g, ') "
    2. Only numbers can be entered with regular expression restrictions: onkeyup= "Value=value.replace (/[^\d]/g,") "Onbeforepaste=" Clipboarddata.setdata (' text ', Clipboarddata.getdata (' text '). Replace (/[^\d]/g, ') "
    3. Only numbers and English can be entered using regular expression restrictions: onkeyup= "Value=value.replace (/[\w]/g,") "Onbeforepaste=" Clipboarddata.setdata (' text ', Clipboarddata.getdata (' text '). Replace (/[^\d]/g, ') "
