Dynamics CRM - Expected Identifier Error in Javascript Code

Posted on 2009-06-28

Hi Experts,

I got this script from a site and just replaced the generic fields in the script with the fields on my form. I am receiving a Javascript error saying 'Expected Identifier' Code 0.

This code basically gets two fields and joins the data into an existing field.

Below is my code.

Many Thanks In Advance.
//Declare your world. 

var strings = new Array(); 

var target = crmForm.all.description; 

//A function that check whether there is a legitimate value further on. 

function checkNext(a,i) { 

if (i >= a.length) { 

return false; 

} else if (a[i] != null && a[i] != "") { 

return true; 


else { 

return checkNext(a,i+1); 



//A function that add a line to an array 

function addLine(l,t) { 

//If lookup field. 

if (t == 1) { 

if (l.DataValue) { 

return l.DataValue[0].name; 

} else { 

return null; 


//If text field. 

} else if (t == 2) { 

return l.DataValue; 

//If picklist field. 

} else if (t == 3) { 

return l.SelectedText; 

} else { 

return null; 



//Add each of the values in order to the array. 

//As the second parameter, enter 1 for lookup fields, 2 for any text field and 3 for picklist fields. 

strings[0] = addLine(crmForm.all.new_service_description,2); 

strings[1] = addLine(crmForm.all.new_service_tasklist,3); 

//Loop through the array and chain its 


for (i=0;i<strings.length;i++) { 

if (strings[i] != null && strings[i] != "" && checkNext(strings,i+1)) { 

if (i==0){ 

target.DataValue = strings[i] + " - "; 

} else { 

target.DataValue += strings[i] + " - "; 


} else if (strings[i] != null && strings[i] 

!= "") { 

if (i==0) { 

target.DataValue = strings[i]; 

} else 


target.DataValue += strings[i];

you might not have put all the fields on the form .

My logic will be

if (crmForm.all.description != null)
 if(crmForm.all.description.DataValue  != null)

  if(crmForm.all.new_service_description != null && crmForm.all.new_service_tasklist != null)
crmForm.all.description.DataValue  += crmForm.all.new_service_description.DataValue + crmForm.all.new_service_tasklist.SelectedText
 if(crmForm.all.new_service_description != null && crmForm.all.new_service_tasklist != null)
crmForm.all.description.DataValue  = crmForm.all.new_service_description.DataValue + crmForm.all.new_service_tasklist.SelectedText
