Select Weekdays in the date field

[asifnoor]

In this article, today i will share you a code snippet which will allow user to to select only a weekday from any of the date field in your form. If weekend is selected, we will show an error message.

For this, we need 2 scripts

Client Script: OnChange to select the changed value

Script Include: To check if the date is a weekday or weekend.

Client Script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   //Show error when weekend is selected
   var ga = new GlideAjax("selectWeekday");
   ga.addParam("sysparm_name","isWeekDay");
   ga.addParam("sysparm_date",newValue);
   var response = ga.getXMLAnswer(parseResponse);
    function parseResponse(answer) {
	if(answer == 'true') {
	      g_form.showFieldMsg('expected_start','Select any weekday','error',true);
	}
    }
}

Script Include

var selectWeekday = Class.create();
selectWeekday.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    isWeekDay: function() {
		var selected_date = this.getParameter("sysparm_date");
		var d = new GlideDateTime(selected_date);
		//Monday -1 sunday -7
		if(d.getDayOfWeekLocalTime() > 5){
			return true;
		} else {
			return false;
		}
	},
    type: 'selectWeekday'
});
