Dynamics CRM 365 - Encoding and Decoding Query String Parameters

Posted on by Community Member Microsoft Employee

Hey everyone,

In Dynamics CRM 365 (On-Premise), I am having issues trying to pass a customer name from one entity to another and having the string get decoded correctly.

On my incident entity, I have a ribbon button that opens a custom entity and passes a customer name with the following code snippet:

var parameters = "";
parameters += "&parameter_customerName=" + "This is a customer name with & symbol";

window.open("/main.aspx?etn=customEntity&pagetype=entityrecord&extraqs=" + encodeURIComponent(parameters), "_blank", features, false);

Now the code for the onLoad event for the custom Entity:

var parameters = Xrm.Page.context.getQueryStringParameters();
var passedCustomerName = parameters["parameter_customerName"];
alert(passedCustomerName);

var passedCustomerNameDecoded = decodeURIComponent(parameters["parameter_customerName"]);

alert(passedCustomerNameDecoded);

Both alerts are showing me the same string of text which is: This is a customer name with

However, the URL of the custom entity does have the fully encoded parameter - parameter_customerName%3DThis%20is%20a%20customer%20name%20with%20%26%20symbol

I am aware that window.open should not be used in place of Xrm.Utility.openEntityForm but I have some business requirements that I can meet with window.open such as choosing a window size.

Any suggestions would be greatly appreciated and I'm hopeful that I am simply just decoding this incorrectly.

Thank you,

Francesco,

Thank you for the solution on this one.

Unfortunately, the first solution did not work but replacing the & symbol 'myself' using .replace worked just fine.

This approach should work in my case because this is the only symbol I would expect to be used in this situation.

Thanks again.

Ravi,

Thank you again for responding to my posts and helping me out.

Maybe I implemented it incorrectly but using encodeURI without encodeURIComponent with window.open caused some authentication issues on my entities and I was getting invalid authorization errors when trying to launch the custom entity.

Thanks!

RE: Dynamics CRM 365 - Encoding and Decoding Query String Parameters

Hi,

Instead of "encodeURIComponent()/decodeURIComponent()" use "encodeURI()/decodeURI()".

** encodeURIComponent encodes the special chracters whereas encodeURI doesn't.

Hope this helps.

RE: Dynamics CRM 365 - Encoding and Decoding Query String Parameters

Hi AnimalHealthCRM,

i suspect the trick was made by Xrm.Page.context.getQueryStringParameters() which could misrepresent encoded & like an encoded parameter separator.

The solution maybe a double encoding like the following:

var str = "my name & your name"; var enstr1 = encodeURIComponent(str); var enstr2 = encodeURIComponent(enstr1); alert(enstr2); var destr2 = decodeURIComponent(enstr2); var destr1 = decodeURIComponent(destr2); alert(destr1);

If this solution doesnt work, your last change is to replace & character before to send querystring and restore it after retrieve, like:

var str = "my name & your name"; var str1 = str.replace("&","__AND__"); var enstr1 = encodeURIComponent(str1); alert(enstr1); var destr1 = decodeURIComponent(enstr1); var str2 = destr1.replace("__AND__","&"); alert(str2);

Please let me know if you solve.
