I'm making a simple Multiple Choice Question form. I want to put validation that if a user clicks on Question <textarea>
and clicks somewhere else on page while not entering value in <input type="text" name="q1_option1">
of options of the question, then the user should get an alert("Wait, you forgot to enter options for Question 1");
. I tried doing it like this but it's simply not the thing that i want.
Here is the <html>
<div class="right">
<div class="row" style="margin:5px;">
<label><strong>Question 1</strong></label>
<div>
<textarea name="question1"></textarea>
</div>
</div>
<div class="row">
<div class="span-4"><input type="text" name="q1_option1" value="" class="q1" /></div>
<div class="span-4"><input type="text" name="q1_option2" value="" class="q1" /></div>
<div class="span-4"><input type="text" name="q1_option3" value="" class="q1" /></div>
<div class="span-4"><input type="text" name="q1_option4" value="" class="q1" /></div>
<div class="clear"></div>
</div>
</div>
And this is <script>
<script type="text/javascript">
$(function(){
$('textarea[name=question1]').blur(function(){
$('.right').click(function(event) {
if($(event.target).is('input[name=q1_option1]')) {
$('#alert_error_message').text('Please enter all options in Question 1!!');
callalert();
return false;
}
else
{
alert('Not working!');
}
})
})
})
</script>
Now what is happening in this code, when the user clicks on <input>
to enter the options, blur
is fired and user gets the alert.
What i want that if a user clicks on these <input>
of answers, he should not get the alert, else, the user must get the alert for not entering values in the <input>
of options!!
I came up with below approach and I will explain what I am doing with the below code. Check for the inline comments.
$(function(){
var hasFocus=false; //this variable is used to check whether focus was on textarea
//when clicked on document
$('textarea[name=question1]').blur(function(event){
setTimeout(function(){
hasFocus=false; //on blur set the variable to false but after sometime
},100);
}).focus(function(){
hasFocus=true; //on focus set it to true again
});
//A click event on document so that to display alert only if textarea had focus and the
//targetted element is not radio button
$(document).on('click',function(e){
if($(e.target).attr('class')!='q1' && hasFocus && $(e.target).attr('name')!="question1")
{
if(!$('.q1:checked').length) //if any radio has been checked
{
//if not checked then display alert
alert('Please select an option');
}
}
});
})
