“检查"多个复选框单击 &拖? [英] "Check" Multiple Checkboxes With Click & Drag?
问题描述
我有一个充满复选框的表格,如下所示:
I have a table filled with checkboxes like so:
我希望能够按住鼠标并拖动以激活多个复选框.我不知道从哪里开始:/我搜索了答案,但只找到了 另一个话题,有人问怎么做,但没有答案.
I'd like to be able to keep my mouse held down and drag to activate multiple checkboxes. I don't have the slightest clue where to start with this :/ I searched for an answer, but only found another thread of someone asking how to do it, but with no answers.
HTML:
<table>
<tbody>
<tr>
<td><input type="checkbox"></td>
<td><input type="checkbox"></td>
<td><input type="checkbox"></td>
</tr>
<!-- Repeat tr 2x -->
</tbody>
</table>

另外,我更愿意保留 <input type="checkbox">
模型,因为改造我的系统会很耗时,但如果不是这样,我愿意接受其他选择不可能.任何帮助将不胜感激!
Also, I'd prefer to keep the <input type="checkbox">
model because reworking my system would be time consuming, but I'm open to other options if this isn't possible. Any help will be greatly appreciated!

</table>
<script>
function check(id)
{
if(mouseDown)
{
document.getElementById(id).checked = 1-document.getElementById(id).checked;
// document.getElementById(id).checked = true;
// ^ If you only want to turn them on, use this.
}
}
var mouseDown = 0;
document.body.onmousedown = function()
{
++mouseDown;
}
document.body.onmouseup = function()
{
--mouseDown;

或者,使用下面的代码来避免 ID:
Or, alternatively, use the code beneath to avoid IDs:
<table>
<tbody>
<tr>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
</tr>
<tr>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
</tr>
<tr>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
<td><input onmouseover='check(this)' type="checkbox"></td>
</tr>
</tbody>
</table>
<script>
function check(box)
{
if(mouseDown)
{
box.checked = 1-box.checked;
// box.checked = 1;
// ^ If you only want to turn them on, use this.
}
}
var mouseDown = 0;
document.body.onmousedown = function()
{++mouseDown;}
document.body.onmouseup = function()
{--mouseDown;}
