jquery+ Regular + text box can only input the realization method of the number _jquery

A small feature in a Web site that requires users to enter only 16 digits.

Try the JavaScript method:

For example: One method:

Only allow input number
     function Checkkey2 (value, e) {
       var key = window.event? E.keycode:e.which;
       if (Key > && key < 106) | | (Key > && key < 60)) {

       }
       else if (key!= 8) {
         if (window.event)//ie
         {
           e.returnvalue = false; 
         }
         else//firefox
         {
           e.preventdefault ();
         }
       };
     

Another method:

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, ') " 

The above two methods I have used, but there are a number of problems, such as browser compatibility issues, can not achieve the desired effect, so, finally consider using the regular to write their own.

Direct code, very simple regular expression:

Page effect:

Browser compatibility:

I am under the IE7.8.9.10, firefox,chrome under the test can be.

The above is a small series for everyone to bring jquery+ regular + text box can only enter the realization of the number of the full content, I hope that we support cloud-Habitat Community ~
