Playwright: Get the value of input field, textarea, select element

Locator.inputValue() (or) page.inputValue() method return the input.value for the selected <input>, <textarea> or <select> element.

 

Signature

String inputValue()
String inputValue(InputValueOptions options)

 

Approach 1: Using ‘page.inputValue(selector)’. This method returns the input.value for the selected <input>, <textarea> or <select> element.

String value1 = page.inputValue(selector);

Approach 2: Using ‘page.locator(selector).inputValue()’. This method returns the input.value for the selected <input>, <textarea> or <select> element.

String value2 = page.locator(selector).inputValue();
