复选框列表的Javascript [英] Javascript for check box list
问题描述
我的aspx页面上有四个复选框列表.
场景是每个复选框列表都有不同值的复选框.
我希望当任何用户单击这些复选框时,如果所有选中的复选框的值之和超过1,则显示总和超过1
我正在使用以下javascript函数
I have four check box list on my aspx page.
The scenario is that each check box list have check boxes with different-different value.
I want that when any user click on those check boxes then sum of value of all selected checkboxes if crosses 1 then it shows a message like that it exceeds 1
i am using the following javascript function
<script type="text/javascript" language="javascript">
//-------------------function hardcode to perform on checklist box--------
var total = 0;
var histvalue = 0;
var valueOfbx = 0;
var currvalue = 0;
function MutExChkList(chk) {
if (chk.checked) {
valueOfbx = 0;
var chklst = chk.parentNode.parentNode.parentNode;
var chkbx = chklst.getElementsByTagName("input");
for (var i = 0; i < chkbx.length; i++) {
if ((chkbx[i].checked == true) && (chkbx[i].value != chk.value)) {
valueOfbx = Number(chkbx[i].value);
histvalue = -1;
chkbx[i].checked = false;
}
else if ((chkbx[i].checked == true) && (chkbx[i].value == chk.value)) {
currvalue = Number(chkbx[i].value);
}
}
total = total + currvalue;
if (histvalue == -1) {
total = total - valueOfbx;
histvalue = 0;
}
if (total > 1) {
total = total - Number(chk.value);
chk.checked = false;
alert("exceeds");
}
else
chkbx[i].checked = false;
}
else {
total = total - Number(chk.value);
}
}
</script>
它在我的系统上完美运行,但是当我尝试在其他系统上运行时,它没有复选框的价值
请帮帮我
在此先感谢
it works perfectly on my system but as i tried to work this on other systems then it does not value of checkboxes
Please help me
Thanks in advance
推荐答案
var chklst = chk.parentNode.parentNode.parentNode;
也许这就是将代码传输到另一个HTML页面时出现问题的原因.
尝试检查控件的层次结构是否仍然相同.
Maybe that''s what makes the problem when transferring the code to another HTML page.
Try to check the hierarchy of controls if it still the same.
