pass a c# variable to javascript function

Question

I'm trying to pass ac# variable as an argument to a java-script function like

<%var count=model.SomeMode.Count();%>

when i pass it to my java script function "checkAll(count)" it does not fire but without the argument its workin fine

<a  href="#" onclick="return checkAll(count);">CheckAll</a>

Answer 1

Remember the page gets created however you wish. So, you could do something like:

<script type="text/javascript">
  var count = <%=model.SomeMode.Count(); %>;
</script>

You could apply the same logic in method calls, so you could do:

<a  href="#" onclick="return checkAll(<%=model.SomeMode.Count(); %>);">CheckAll</a>

Answer 2

Javascript无法直接看到您的C＃源代码-您需要将其写入服务器端的Javascript源代码中：

<a  href="#" onclick="return checkAll(<%= count %>);">CheckAll</a>

Answer 3

It should look like this:

<script type="text/javascript">
  var count=<%=model.SomeMode.Count()%>;
</script>

Currently you're declaring your variable in C#, not outputting it in the page as a JavaScript one. Instead, you want to declare var count literally in the page and have it set to the output of model.SomeMode.Count() .

Answer 4

This might be good for your solution:

<a  href="#" onclick='return checkAll(<%=count%);'>CheckAll</a>

But there is an other way of doing this instead of conventional way:
