Activate input field from input checkbox
提问by Seth Urquhart
I want to activate the input field from checking the checkbox.
我想通过选中复选框来激活输入字段。
I have a basic form here:
我在这里有一个基本形式：
<ul>
<li>
<label id="form-title" for="name3">Specifics:</label>
<li>
<textarea id="name3" name="name3" >
</textarea>
</li>
</ul>
You click on the "Specifics and it activates the field. Can this be done with an input tag instead of a label tag?
您单击“Specifics”并激活该字段。这可以使用输入标签而不是标签标签来完成吗？
Example:
例子：
<ul>
<li>
<input type="checkbox" for="name2">Other...</input>
<input id="name2" name="name2" />
</li>
</ul>

You will need a little EMCAScript for that.
为此，您需要一点 EMCAScript。
<label for="name3">
<input type="checkbox" id="name3activaitor" onclick="if(this.checked){ document.getElementById('name3').focus();}" />
Other...
</label>
<input type="text" id="name3" name="name3" />
The inline handler sees if the checkbox has been checked, and if it has, focuses the text input. I put the checkbox in the label just to symantically group it with the label as it preforms the same function, but you can put the checkbox anywhere you would like.
内联处理程序查看复选框是否已被选中，如果已选中，则聚焦文本输入。我将复选框放在标签中只是为了将它与标签进行符号分组，因为它执行相同的功能，但是您可以将复选框放在任何您想要的位置。
If you are looking to enable/disable the input field rather than just focus it, you can do like so
如果您希望启用/禁用输入字段，而不仅仅是聚焦它，您可以这样做
<input type="checkbox" onclick="var input = document.getElementById('name2'); if(this.checked){ input.disabled = false; input.focus();}else{input.disabled=true;}" />Other...
<input id="name2" name="name2" disabled="disabled"/>

The attribute for doesn't exist for input tag. For your purpose, use inline javascript code and attribute disabled:
输入标签的属性不存在。出于您的目的，请使用内联 javascript 代码并禁用属性：
<input type="checkbox" id="checkbox1" onclick="if (this.checked){ document.getElementById('textarea1').removeAttribute('disabled');}" />
<textarea id="textarea1" name="textarea1" disabled></textarea>
