清除表单上的按钮设置 [英] Clear button Settings on a form
问题描述
我正在使用表单,并想知道是否有人知道一些可以编辑清除按钮实际清除的字段的JavaScript?
I am using a form and was wondering if anyone knows some JavaScript that can edit what fields the clear button actually clears?
即使用户点击表单上的清除按钮,我只希望清除一定数量的字段。
i.e i only want a select number of fields to be cleared once the user hits the clear button on the form.
input id='FrmReset' type='reset' value='Clear' name='resetButton' onclick='formReset(document.getElementById("Form")); return false;'
我只有以下几项清除了所有内容
I just have the following which clears everything
<input id='FrmReset' type='reset' value='Clear' name='resetButton' onclick='formReset(document.getElementById("Form")); return false;' />
推荐答案
假设您有4个字段, p>
Let's say you have 4 fields like this:
<input type="text" value="don't clear this" id="i1" />
<input type="text" value="don't clear this" id="i2" />
<br/>
<input type="text" value="clear this" id="i3" />
<input type="text" value="clear this" id="i4" />
您只需要清除底部的内容2.添加一个带有onclick事件的普通按钮:
And you need to clear only bottom 2. Add a normal button with onclick event:
<button onclick="clearNeeded()">Clear only bottom fields</button>
function clearNeeded() {
document.getElementById('i3').value='';
document.getElementById('i4').value='';
}
正如您所看到的 - 该函数有选择地只选择特定的字段并重置其值。
As you can see - the function selectively picks only specific fields and resets their values.
