The best way to check if an object is empty is by using a utility function like the one below.

JavaScript: HTML Form – checking for non empty field

1. Javascript function to check whether a field is empty or not // If the length of the element’s string is 0 then display helper message function required(inputtx) { if (inputtx.value.length == 0) { alert(“message”); return false; } return true; }
2. Flowchart:

IsNullOrEmpty() function has a boolean return type and returns true if the string is either null or empty and otherwise returns false . We can use the String. IsNullOrEmpty() function on the string inside the TextBox. Text property to check whether the text inside the text box is empty or not.

1. function isEmpty(obj) { for(var key in obj) { if(obj.
2. var myObj = {}; // Empty Object if(isEmpty(myObj)) { // Object is empty (Would return true in this example) } else { // Object is NOT empty }
3. Object.

var element = driver. findElement(webdriver.By.id(“your elements id”)); //store text var text = element. getText(); //store value var value = element. getAttribute(“value”); //after that you can do anything you want with these variables.

To check if the input text box is empty using jQuery, you can use the . val() method. It returns the value of a form element and undefined on an empty collection.

Your carrier stores text messages for a while after they’ve been deleted, and they may be able to retrieve what you need. It’s unlikely, however, that your carrier will recover deleted text messages if the reason for your request is minor, but it doesn’t hurt to ask if you want to try.
