How to set field(catalog variable) value on requested item using client script

[sayan3]

Hi All,
We have one catalog variable type (select box). available choices are yes/no
default value is empty.
we are trying for particular condition , field value should be set to "No" and read only on requested item label.
so we are using on load client script but g_form.setValue('field_name',''); is not working.
How to achieve this.

Can you provide your script and a little more clarification. You say you want to set it to No on particular conditions but then in your onload script you are setting it to the default value of empty. If the default value is empty you should not have to set it onload.

Edit: Also when the form is loading is this variable visible?

Hi,

Please use the below steps to achieve your requirement:

function onLoad() {
    //Type appropriate comment here, and begin script below
    if (g_form.getValue('FIELDNAME') == '') { // Replace your Field Name here
        g_form.setValue('variables.VapriableName', 'no'); // Replace Variable Name here and also the correct value of "no" which you can get from your Select Box Variable choice backend value
		g_form.setReadOnly('variables.VariableName',true); // Replace your Varibale Name here/
    }
}

Hope this helps. Please mark the answer as correct/helpful based on impact.
