我希望我的表单提交按钮被禁用/启用,具体取决于表单是否已完全填充.
当输入填充时,禁用的按钮更改为启用.这很好.
但是我希望在输入输入时禁用该按钮.
这是我的脚本:
<script type="text/javascript" language="javascript"> function checkform() { var f = document.forms["theform"].elements; var cansubmit = true; for (var i = 0; i < f.length; i++) { if (f[i].value.length == 0) cansubmit = false; } if (cansubmit) { document.getElementById('submitbutton').disabled = false; } } </script> <form name="theform"> <input type="text" onKeyup="checkform()" /> <input type="text" onKeyup="checkform()" /> <input id="submitbutton" type="submit" disabled="disabled" value="Submit" /> </form>
