强制进行校验文本字段的键盘输入,用户只能输入数值
有几个在线资源描述这个 (e.g. http://stackoverflow.com/questions/995183/how-to-allow-only-numeric-0-9-in-html-inputbox-using-jquery, http://snipt.net/GerryEng/jquery-making-textfield-only-accept-numeric-values, etc.).
例如,如果您的文本字段ID是“numeric”,则可以使用此示例脚本:
<script> $(document).ready(function() { $("#numeric").keydown(function(event) { // Allow only backspace and delete if ( event.keyCode == 46 || event.keyCode == 8 ) { // let it happen, don't do anything } else { // Ensure that it is a number and stop the keypress if (event.keyCode < 48 || event.keyCode > 57 ) { event.preventDefault(); } } }); }); </script>
