jQuery Basic Syntax

 In Microsoft D365, jQuery is mostly used in different CRM portal for development purpose.

Providing basic syntax required to Get/Set field value in jQuery : 

1. TextField : 

var firstname = $("#firstname").val();  //get

var lastname = $("#lastname").val("Tendulkar");  //set 

2. OptionSet : 

var type = $("#typecode").val(); //get

var type = $("#typecode").val(16350000);  //set (enter code of optionset field)

3. Lookup : 

//Get Lookup Value
var lookupGUID = $(“#new_accountid”).val();
var lookupValue = $(“#new_ accountid_name”).val();
var entityName= $(“#new_accountid_entityname”).val();
                   
//set Lookup Value 
$(“#new_accountid”).val(lookupId);
$(“#new_accountid_name”).val(lookupName);
$(“# new_accountid_entityname”).val(EntitySchemaName);

4. CheckBox : 

//Get Checkbox value
var isChecked = $(“#{field_name}”).is(“:checked”);
if (isChecked == true) {
alert(“Checked!”);
}
else if (isChecked == false) {
alert(“Unchecked!”);
}

//set CheckBox Value 
$(‘#{fieldname}’).prop(‘checked’, true);

5. Radio Button : 

Radio button has 2 controls (eg. Yes and No). Hence, we need to get/set both the controls value as per business requirement.

//Get two controls of radio button

var isOption1Checked = $(“#{field_name_0}”).is(“:checked”); //Returns true/false

var isOption2Checked = $(“#{field_name_1}”).is(“:checked”); //Returns true/false
         
//Set two controls of radio button
                         
// To setRadio 1 to 'true'
         
$(‘#{fieldname_0}’).prop(‘checked’, true);

// To set Radio 2 to ‘true’

$(‘#{fieldname_1}’).prop(‘checked’, true);

6. On Change of field (text/lookup/optionset) : 

$("#new_name").change(function() {
//call your function or apply your logic here!
});
