Using JavaScript in a custom button in CRM 2011

Now let us built on our existing example of adding custom button.

Now on click of the button I want to show alert message “Hello World” i.e. call JavaScript.

This is our existing Button Definition

LabelText=My First Button
ToolTipTitle=My First Button Tool Tip Title
ToolTipDescription=My First Button Tool Tip Description

(Add a new Jscript web resource to the solution named MyJavaScript)

function HelloWorld() {

alert(‘Hello World’);


Now add a Command attribute to Button

    <Button Id=”B_MyFirstButton


                            LabelText=”My First Button ToolTipTitle=”My First Button Tool Tip Title ToolTipDescription=”My First Button Tool Tip Description TemplateAlias=”o1 Image16by16=”/_imgs/ribbon/saveandclose16.png Image32by32=”/_imgs/ribbon/saveandclose32.png“/>

Now we need to define this Command.

This is how we can define it











However if we zip and import this solution, the button would appear disabled.

To enable it we need to add EnableRule to it.













Now after importing and publishing it

The final RibbonDiffXml looks like this

LabelText="My First Button"
ToolTipTitle="My First Button Tool Tip Title"
ToolTipDescription="My First Button Tool Tip Description"

Hope it helps!

  1. When trying to import the sollution after editing, I recieve an error because of invalid XML. Looking at Technical Details, it states the following:

    The import file is invalid. XSD validation failed with the following error: ‘The ‘command’ attribute is not declared.

    Do you know why this happens?



  2. I tried your example but for some reason me javascript is not executing, Following is what i did:
    1. Exported Account Entity
    2. Added following in Tag

    3. Added following in Tag

    4. Created a Web Resource with new_Helloworld name.
    5. Imported the zipped file.
    The button did got visible but onlick the javascript did not get executed. Any comments would be of great help.


  3. Note that if you copy paste code from this blog, you must replace the “ and ’ characters by ” and ‘ respectively.

    I advice the author to not use these characters when posting code.


  4. I gave namespace in javascript and gave full path name. But button is disabled. When I gave on function name, it is enabled but no action on click. How do I give function name if I use namespace in JScript?
