How to get entry value from form control value-CodePudding

I have a general question. I have a form with view input fields. In the input field I can set for example names and then be able to submit the form.

In the second step, I can view this form with already filled input fields and can generate new empty fields.

For the already filled input fields I would like to render a button but only if the field already has an input from previous submit.

I am asking myself whether there is a way to check whether input field has already an input and the input field is hence disabled

CodePudding user response：

Yes it is possible there are some ways to do it.

this.form.value; // It will give you a complete form object.

this.form.get("controlName").value; // it will give yo you the controller value only.

this.form.controls.controlname.value; // it will give yo you the controller value only.
