我有一个下拉框和一些文本输入字段。根据用户选择的下拉菜单中的哪个项目,我想禁用一些字段。我想我没有正确定位输入字段,但我无法弄清楚问题是什么:
这是我到目前为止所获得的剧本:
$(document).ready(function(){
var customfield = $('#customfields-tf-19-tf');
var customfield1 = $('#customfields-tf-20-tf');
var customfield2 = $('#customfields-tf-13-tf');
$(function() {
var call_table = {
'Condominium': function() {
customfield.attr("disabled");
},
'Co-Op': function() {
customfield1.attr("disabled");
},
'Condop': function() {
customfield2.attr("disabled");
}
};
$('#customfields-s-18-s').change(function() {
call_table[this.value]();
});
});
});
我的表单的布局:
<td width="260" class="left">
<label for="customfields-s-18-s">Ownership (Required):</label>
</td>
<td class="right">
<select name="customfields-s-18-s" class="dropdown" id="customfields-s-18-s" size="" >
<option value="Condominium"> Condominium</option>
<option value="Co-Op"> Co-Op</option>
<option value="Condop"> Condop</option>
</select>
</td>
</tr>
<tr>
<td width="260" class="left">
<label for="customfields-tf-19-tf">Maintenance:</label>
</td>
<td class="right">
<input type="text" title="Maintenance" class="textInput" name="customfields-tf-19-tf" id="customfields-tf-19-tf" size="40"/>
</td>
</tr>
<tr id="newsletter_topics">
<td width="260" class="left">
<label for="customfields-tf-20-tf">Taxes:</label>
</td>
<td class="right">
<input type="text" title="Taxes" class="textInput" name="customfields-tf-20-tf" id="customfields-tf-20-tf" size="40" />
</td>
</tr>
<tr>
<td width="260" class="left">
<label for="customfields-tf-13-tf" class="required">Tax Deductibility:</label>
</td>
<td class="right">
<input type="text" title="Tax Deductibility" class="textInput" name="customfields-tf-13-tf" id="customfields-tf-13-tf" size="40" />
</td>
</tr>

我相信为了禁用您需要使用的输入:
$(input).attr("disabled", "disabled");
此外,其中一些功能可能对您有用:
$.fn.enable = function() {
return this.removeAttr('disabled');
}
$.fn.disable = function() {
return this.attr('disabled', 'disabled');
}
$.fn.disenable = function(val) {
if (val)
return this.enable();
else
return this.disable()
}
$.fn.toggleEnabled = function() {
if (this.attr('disabled') == 'disabled')
return this.enable();
else
return this.disable();
}
一旦定义了它们,就可以在任何jQuery变量上使用它们,如下所示:
$(input).toggleEnabled();
