Question

I am working on a CRM system that allows me to write custom HTML and JavaScript inside its interface, and I can reference CRM variables (such as current process status, date, etc) by using hash values #variable.variablename#. So I tried to write the following JavaScript but the problem is that no links will be displayed regardless of if any of the three variables exists or not:

<script type="text/javascript">
if ( #variable.1# != null) {
<div><a href="/Service1.svc/vf/img?imgid=5#variable.1#" >View Page</a></div> }

if ( #variable.2# != null) {
<div><a href="/Service1.svc/vf/img?imgid=5#variable.2#" >View Page</a></div>
}

if ( #variable.3# !=null) {
<div><a href="/Service1.svc/vf/img?imgid=5#variable.3#" >View Page</a></div>
}

</script>

What might be the problem ?

Answer 1

I would guest that the content of #variable.1# (2 and 3) isn’t valid javascript. Maybe you need to enclose them in quotes, like "#variable.1#"

Also, you need to document.write the html – you can’t just put it on a line and expect to appear.

<script type="text/javascript">
var html = '';
if ( "#variable.1#" != null) {
    html += '<div><a href="/Service1.svc/vf/img?imgid=5#variable.1#" >View Page</a></div>'
}

if ( "#variable.2#" != null) {
    html += '<div><a href="/Service1.svc/vf/img?imgid=5#variable.2#" >View Page</a></div>'
}

if ( "#variable.3#" !=null) {
    html += '<div><a href="/Service1.svc/vf/img?imgid=5#variable.3#" >View Page</a></div>'
}

document.write(html);

Also, consider using “View source” (Ctrl+U on Firefox) to see the actual Javascript, you’ve constructed.
