How to calculate length of input from single line text variable?

[Ashwini Jadhao]

HI Community,

I have created "Provide code" as single line text and adding some input in it and now want to calculated length of  "Provide code"  variable's input.

I am doing it in widget.

Could you please help me to get length through widget scripting.

Give your input type a model value, and access it in your client function.

HTML:

<input type="text" class="form-control" ng-model="provideCode" ng-change="c.getCount()"/>

Client Controller:

api.controller=function($scope) {
  /* widget controller */
	var c = this;
	
	c.getCount = function()
	{
		alert($scope.provideCode.length);
	};

	
};

Hi,

Have you tried using below logic:

var length1 =g_form.getValue('provide_code').length.toString();

or 

var length1 =g_form.getValue('provide_code').length;

Thanks,
