Notify when the focus is solely on the text box

How can I display an alert only when the focus is on a text box? Currently, I am getting an alert whenever I skip the text box or click anywhere on the page. The alert even appears when I open a new tab. Is there a way to fix this issue? Thank you for your help.

$(function() {
    $("input").blur(function() {
    if(!this.value) {
      alert("Text box " + ($(this).index() + 1) + " cannot be empty.");
      this.focus(); //Keep focus on this input
    }
});

body section

<input type="text" id="textbox1"/>
<input type="text" id="textbox2"/>
<input type="text" id="textbox3"/>
<input type="text" id="textbox4"/>

  $(function() {
        $('input:text').blur(function() {
            if(!this.value) {
                alert("Please fill in text box " + ($(this).index() + 1));
                this.focus(); //Keep focus on this input field
            }
        });
    });

Answer №2

  <script type="text/javascript>
        function showAlertMessage(inputText) {
                if (!inputText.value) {
                    alert("Please fill out the text box.");
                    inputText.focus(); //Keep focus on this input field
                }

        }; 
    </script>

<input type="text" id="textbox1" onfocus="showAlertMessage(this)"/>

I trust that this solution addressed your issue.

Answer №3

Give this a shot:

$(function() {
   $("input[type=text]").blur(function() {
       if (!this.value && $(document.activeElement).attr("type") == "text") {
          alert("Text box " + ($(this).index() + 1) + " cannot be left blank.");
          this.focus();
       }
    });
});

The use of document.activeElement allows you to identify the currently selected element and check if it is a text box.

Hopefully, this explanation proves useful!
