Explain startsWith() function

[Sid_Takali]

Hi all, 

 I have a requirement to check a string field (compare with another field which is on another form)  and if it starts with certain word then execute a else if() block.  

function onLoad() {
   //Type appropriate comment here, and begin script below
   var value= g_form.getValue('initiated_from');
    if (value=='')
    {
        g_form.setValue('u_tracking_type',1);
    }

    else if(value.startsWith("CS")) // 
        {
            g_form.setValue('u_tracking_type',2);
        }
}

The startsWith() method returns true if a string starts with a specified string.

Otherwise it returns false.

The startsWith() method is case sensitive.

Hi Siddharam,

As per my understanding startsWith() does not work in client script you can use alternatives such as indexOf() or substring()

So, something as below

indexOf()

function onLoad() {
   //Type appropriate comment here, and begin script below
   var value= g_form.getValue('initiated_from');
    if (value=='')
    {
        g_form.setValue('u_tracking_type',1);
    }

    else if(value.indexOf("CS")>-1) // 
        {
            g_form.setValue('u_tracking_type',2);
        }
}

substring()

function onLoad() {
   //Type appropriate comment here, and begin script below
   var value= g_form.getValue('initiated_from');
    if (value=='')
    {
        g_form.setValue('u_tracking_type',1);
    }

    else if(value.substring(0,2)=="CS") // 
        {
            g_form.setValue('u_tracking_type',2);
        }
}

To what Jaspal said, I think another way is indexOf but can be alternatively be used as:

else if(value.indexOf("CS")== 0) // check if CS value string starts with CS
        {
            g_form.setValue('u_tracking_type',2);
        }

Feel free to mark correct, If I answered your query.
