jQuery的复选框中的问题被禁用按钮 [英] jQuery disabled button with checkbox issue
问题描述
我有以下的code这使得当复选框被选中的按钮。
以下是从code我有我的HTML页面片段。这是很多但是由于某种原因,它不工作一样。我想我可能一直在寻找太久。
<脚本类型=文/ JavaScript的'>
$(函数(){
$('#同意)。点击(函数(){
。VAR满足= $('#同意:检查)VAL();
如果(满意=未定义!)$('#提交)removeAttr(禁用)。
否则$('#提交)ATTR(禁用,禁用)。
});
});
< / SCRIPT><形式为GT;
<表>
< TD合并单元格=5><输入类型=复选框ID =同意NAME =同意/ I标记已阅读并同意条款和 条件< / TD>
< / TR>
&所述; TR>
< TD合并单元格=5ALIGN =中心><输入名称=提交类型=提交ID =提交残疾值=我接受。 提交/>
<标签>
<输入名称=复位TYPE =重置ID =复位值=重置/>
<输入类型=隐藏的名字=IP值=回声$ REMOTE_ADDR;/>
< /标签>< / TD>
< / TR>
&所述; TR>
< TD> *必须填写< / TD>
< TD合并单元格=4>< / TD>
< / TR>
&所述; TR>
< TD合并单元格=5>< H3>< / H3 GT&;
&所述p为H.;&放大器; NBSP;&下; / P>&下; / TD>
< / TR>
< /表>
< /字段集>
< /表及GT;
您还可以设置禁用
与真正
和假
,所以您可以简化它归结为:
$(函数(){
$('#同意)。改变(函数(){
$('#提交)ATTR(禁用,this.checked!)。
});
});
测试一下这里,注意,以前也有一些无效的标记回事致使一些跨浏览器的不一致,就应该是这个样子:
<形式为GT;
<表>
< TR>< TD ALIGN =中心><输入类型=复选框NAME =同意ID =同意>我同意条款和条件与LT; / TD>< / TR>
< TR>< TD ALIGN =中心><输入类型=提交名称=提交ID =提交值=提交残疾>< / TD>< / TR>
< /表>
< /表及GT;
另外, .change()
方法是一个好一点这里,以确保你有正确的状态。
I have the following code which enables a button when the checkbox is checked.
The following is a snippet from the code I have in my HTML page. It's much the same however for some reason it's not working. I think I may have been looking at it for too long.
<script type='text/javascript'>
$(function() {
$('#agree').click(function() {
var satisfied = $('#agree:checked').val();
if (satisfied != undefined) $('#submit').removeAttr('disabled');
else $('#submit').attr('disabled', 'disabled');
});
});
</script>
<form>
<table>
<td colspan="5"><input type="checkbox" id="agree" name="agree" />I have read and agree to the terms and
conditions</td>
</tr>
<tr>
<td colspan="5" align="center"><input name="Submit" type="submit" id="submit" disabled value="I Accept.
Submit"/>
<label>
<input name="reset" type="reset" id="reset" value="Reset" />
<input type="hidden" name="ip" value=" echo $REMOTE_ADDR; " />
</label></td>
</tr>
<tr>
<td>*Required Fields</td>
<td colspan="4"></td>
</tr>
<tr>
<td colspan="5"><h3></h3>
<p> </p></td>
</tr>
</table>
</fieldset>
</form>
You can also set disabled
with true
and false
, so you can simplify it down to:
$(function() {
$('#agree').change(function() {
$('#submit').attr('disabled', !this.checked);
});
});
Test it out here, note there was also some invalid markup going on resulting in some cross-browser inconsistencies, it should look something like this:
<form>
<table>
<tr><td align="center"><input type="checkbox" name="agree" id="agree">I agree Terms and Conditions</td></tr>
<tr><td align="center"><input type="submit" name="submit" id="submit" value="submit" disabled></td></tr>
</table>
</form>
Also the .change()
method's a bit better here, to ensure you have the correct state.
