prevent a date field being a date prior to today

[patricklatella]

Hi everyone!

I have a date field Due date (due_date) on a custom table.   I need to prevent entering a date into this field that is prior to today.   To achieve this I've created a client script and an accompanying script include.   I believe I am close, anyone see why it's not working?   thanks!

my onChange client script is:

function onChange(control, oldValue, newValue, isLoading) {  

    if (isLoading || newValue == '') {  

          return;  

    }  

  //make sure they are not asking for a due date in the past (before now)  

  var ga = new GlideAjax("NowDateCalc"); //name of the called script include  

  ga.addParam("sysparm_name", "getNow"); //name of the function in the script include  

  ga.getXML(getDate); //callback function  

}  

function getDate(response) {  

  var due_date = g_form.getValue('due_date');   //due_date is the name of the field on the table

  var rightNow = response.responseXML.documentElement.getAttribute("answer");  

  if (due_date < rightNow) {  

  alert("Due date cannot be earlier than today.");  

  g_form.setValue('due_date', '');  

  }  

}

and my script include, "NowDateCalc" is:

var NowDateCalc = Class.create();

NowDateCalc.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

getNow : function() {

  return gs.now();

},

      type: 'NowDateCalc'

});

Best practice is to take a scriptless solution over a scripted solution when both are available. It's easier to create and maintain. I strongly recommend reconsidering the scriptless business rule above. I use it all the time for date validation.

//Using On change client script.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

var serviceDate = getDateFromFormat(newValue, g_user_date_time_format);

var rightNow = new Date();

if (serviceDate < rightNow) {

alert('Service date cannot be in past please correct it');

g_form.clearValue("service_date");


}

}

//If it is helpfull, please mark it.

Thanks,

After hours of trying to figure this out on my own from a Client Script perspective, this is exactly what i needed. Wish i would've found this in the beginning. bravo
