Hi all,
I need to convert the json string like the following {"name":
{"is":"john"}} to {\"name\": {\"is\":\"john\"}}
I wrote the javascript as follows which works well on the online java
script editor. The script
<!DOCTYPE html>
<html>
<body>
<h2>Create Object from JSON String</h2>
<p id="demo"></p>
<script>
var p ='{"name": {"is":"john"}}';
var x = p.replace(/\"/g,'\\"');
document.write(x);
</script>
</body>
</html>
So I wrote the script in the synapse configuration as below.
<script language="js"><![CDATA[
var q = mc.getProperty('uri.var.query1');
<!--var o = JSON.stringify(q);-->
var qReplacedString = q.replace(/\"/g,'\\"');
mc.setProperty('uri.var.query1',qReplacedString);
]]>
</script>
But it gives me the following errors. Is there any issues on using
/\"/ character
,What would be the problem on this.

But the replace function works well in normal strings. eg
<script language="js"><![CDATA[
var q = mc.getProperty('uri.var.query1');
<!--var o = JSON.stringify(q);-->
var qReplacedString = q.replace("name","hi");
mc.setProperty('uri.var.query1',qReplacedString);
]]>
</script>
Thank You.
