Hi All,
I have a requirement where i need to count the number of characters in a field and display an alert message to the user when it is less than 20.
I am using the following code to execute.
function countchars(){
var fieldtext = Xrm.Page.getAttribute("description").getValue();
if(fieldtext != null){
if(fieldtext.length < 20){
alert(Enter more than 20 characters);
}
}
}
Please advise.

Hi Vignesh,
It looks like your entity is an out of the box entity. If not check the field name as it should have your solution prefix. Anyway if you debug your script you should be easily find where the problem is.
Try looking at following posts to know how to debug javascrips in Dynamics CRM.

You can use addonkeypress function to get how many characters are there in the field at runtime.
Refer this:
Hi Vighnesh,
The problem in the code is with the alert statement. It should be enclosed in quotes.
Replace the code as shown below.

I guess the alertDialog works for updated entities only
Entities were updated in CRM Online 2016 Update 1 and Dynamics 365 Service Pack 1 (on-premises).
Hi
Using alert should work (with the correction, previously mentioned) in web. But it is good to use alertDialog instead.
msdn.microsoft.com/.../jj602956(v=crm.6).aspx
function countchars() {
var fieldtext = Xrm.Page.getAttribute("description").getValue();
if ((fieldtext != null) && (fieldtext.length < 20)) {
Xrm.Utility.alertDialog("Enter more than 20 characters", null);
}
}
Hi
Code looks ok except
alert("Enter more than 20 characters");
