Submit disabled Dropdown，disableddropdown
需求：完成一個不可以改的dropdown，（符合一定logic）在js中設value，並且提交表單時把值提交到server
1.嘗試readonly
<script src="jquery-1.11.1.min.js"></script><form name="frm" method="post"><select id="sel" name="sel"><option value="1" >1</option><option value="2">2</option><option value="3">3</option></select><input type="submit" value="submit" /></form><script>$(document).ready(function(){$("#sel").val(2);$("#sel").attr("readonly","readonly");});</script>
<script src="jquery-1.11.1.min.js"></script><form name="frm" method="post"><select id="sel" name="sel"><option value="1" >1</option><option value="2">2</option><option value="3">3</option></select><input type="submit" value="submit" /></form><script>$(document).ready(function(){$("#sel").val(2);$("#sel").attr("disabled","disabled");});</script>
$(document).ready(function(){ $("#sel").closest("form").submit(function () { $("#sel").removeAttr("disabled"); });$("#sel").val(2);$("#sel").attr("disabled","disabled");});
看看我的例子吧
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<script>
function goo(obj)
{
obj.disabled =true;
document.getElementById("form1").submit();
}
</script>
</HEAD>
<BODY>
<form action="1.asp" method="post" id="form1">
<input type=button value="提交" onclick="goo(this);">
</form>
</BODY>
</HTML>
html submit 的 disabled 屬性 怎取到JS的Boolean值
你是想讓提交按鈕提交後就不能在點了是吧var b=true;function sub(){var su=document.getElementById("sub");if(b){ su.disabled=true; b=false;}else{su.disabled=false;}}<input id="sub" type="submit" value="提交" ${ b? "disabled":"" } onclick="sub();">
