To have once for all the link to show to people,because too much makes the same error again and again.
(From here – you can use ResolveUrl or Url.Content – it’s the same for me. I use ResolveUrl because I used first …)
Case 1 The image does not display
Please check you have the following :
<img src='<%= ResolveUrl("~/Content/images/YOURIMAGE.jpg" )%>' alt="image" style="border:0" />
Case 2 The css does not show
Please check you have the following :
<%= string.Format("<link href='{0}' type='text/css' rel='stylesheet' />",ResolveUrl("~/Content/your.css")) %>
or
<style type="text/css"> @import '<%= ResolveUrl("~/Content/your.css") %>'; </style>
Case 3 The js does not execute (undefined error)
Please check you have the following :
<script type="text/javascript" src='<%= ResolveUrl("~/Scripts/yourjs.js")%>'></script>
Case 4 The js does execute in aspx page,but did not execute under js file
Please check you DO NOT have the following
<%
in the js file. The js file is not interpreted by the same engine as aspx,so can not interpret asp.net tags. Instead,add a parameter to your function : the path.
Simple example : Let’s say in aspx you have :
<script type=”text/javascript”>
function Generate(){
window.open(‘<% Url.Action(“About”)%>’);
}
</script>
and you call Generate();
When you put in .js file,please put this :
function Generate(url){
window.open(url);
}
and call like this :
Generate('<% Url.Action(“About”)%>');
Case 5 The ajax request gives you a 404 error.
Please ensure that you have
<%= ResolveUrl("~/path”)%>
and not
/path
