我正在寻找如何在选中复选框时禁用表单上的所有其他输入。我现在已经到了中途,但是当我点击复选框时出现问题时,它会自动禁用其他元素。我只希望其他元素被禁用。

<form action="#" method="post">
<div>
<label for="checkbox">Checkbox:</label>
<input type="checkbox" name="checkbox" id="checkbox" />
</div>
<div>
<label for="name">Text Input:</label>
<input type="text" name="name" id="name" value="" tabindex="1" />
</div>
<div>
<h4>Radio Button Choice</h4>
<label for="radio-choice-1">Choice 1</label>
<input type="radio" name="radio-choice-1" id="radio-choice-1" tabindex="2" value="choice-1" />
<label for="radio-choice-2">Choice 2</label>
<input type="radio" name="radio-choice-2" id="radio-choice-2" tabindex="3" value="choice-2" />
</div>
<div>
<label for="select-choice">Select Dropdown Choice:</label>
<select name="select-choice" id="select-choice">
<option value="Choice 1">Choice 1</option>
<option value="Choice 2">Choice 2</option>
<option value="Choice 3">Choice 3</option>
</select>
</div>
<div>
<label for="textarea">Textarea:</label>
<textarea cols="40" rows="8" name="textarea" id="textarea"></textarea>
</div>
<div>
<input type="submit" value="Submit" />
</div>
$('#checkbox').click(function () {
var $this = $(this);
// $this will contain a reference to the checkbox
if ($this.is(':checked')) {
$('input:not(this)').attr("disabled", true);
} else {
}
});
答案 0 :(得分:1)
$('#checkbox').change(function(e){
var $form = $(this).closest('form'); // locate the form we're referring to
// alternative method: var $form = $(this.form);
$form.find(':input') // grab all input elements (buttons, inputs, select lists, etc.)
.not(this) // exclude this checkbox
.attr('disabled', !this.checked); // mark these elements as disabled
// based on the checkbox value
});
使用.not()
排除所选内容中的当前元素。如果用户决定在表单中进行制表,我建议绑定到change
而不是click
。
另外,jsFiddle(虽然在演示中我引用了input element this.form
,但您也可以在上面的示例中保留$form
。)< / p>
