I guess you mean restore the original values of the textboxes? If so, here is the required code:
我猜你的意思是恢复文本框的原始值？如果是这样，这里是所需的代码：
<script type="text/javascript">
function RestoreValues() {
var arrInputs = document.getElementsByTagName("input");
for (var i = 0; i < arrInputs.length; i++) {
var oCurInput = arrInputs[i];
if (oCurInput.type == "text")
oCurInput.value = oCurInput.defaultValue;
}
}
</script>
To restore the values just call the function, for example:
要恢复值只需调用该函数，例如：
<button type="button" onclick="RestoreValues();">Restore</button>
