Retrieving a variable value set within a jQuery function from within an Angular 2 component

In the current project, I am facing a situation where I need to work around and initialize jQuery datetimepicker inside an Angular 2 application (with plans to refactor it later).

However, when I assign a datetime value to a variable, I encounter a problem where it is not visible elsewhere in the Angular app. Here is my current approach:

datetime: string;

setDT() {
  jQuery(this.elementRef.nativeElement).find("#datetimepicker").datetimepicker({
    onChangeDateTime: function(currentDateTime) {
      this.datetime = currentDateTime;
      console.log(this.datetime); // -> logs correct selected datetime, i.e. Fri Mar 11 2016 10:00:00 GMT+0200 (EET)
    }
  });
}

Unfortunately, when I try to access this.datetime from another part of the code, it returns 'undefined':

save() {
  console.log(this.datetime); // -> 'undefined'
}

I am seeking guidance on how to effectively pass variables between jQuery and Angular 2.

Regards, Roman

Answer №1

To achieve this, make use of jQuery's proxy method as shown below:

initDateTimePicker() {
  jQuery(this.elementRef.nativeElement).find("#datetimepicker").datetimepicker({
    onChangeDateTime: jQuery.proxy(function(selectedDateTime) {
      this.dateTime = selectedDateTime;
      console.log(this.dateTime); // Logs the correct date and time selected
    }, this)
  });
}

Answer №2

It seems that I managed to obtain the necessary value using

this.datetime = jQuery(this.elementRef.nativeElement).find("#datetimepicker").val();

However, it would be beneficial to receive clarification for educational purposes.

Thank you once more!
