In the js code I have
var a1 = "text in a1";
var right_text = a1;
a1
is the variable where this text is written.
the value of right_text
will change.
I need have more variables like a1
because each of them will do something else.
switch (right_text) {
case a1:
...
case a2:
...
case a3:
...
I would like it to increase value of right_text
to a2
after first click on the button and to a3
after another click and so on.
So I want to get the variable a1
as a string
, add one and get a2
.
But now I need to somehow detect the current value of right_text
, ie a1
, not the content written in a1
.
I tried
right_text.toString ();
But that will return the mentioned content a1
. It could be done somehow so that I can get value of right_text
(a1
in this case) and convert it as string
?
Thank you
Assuming that right_text is a current step var. You can set base value for right_text and a counter.
var right_text = 'a';
var step_counter = 0;
When the user click on your button, increase a counter.
step_counter++;
Now, you can set the current step text :
right_text = 'a' + step_counter;
When you display right_text, your output will be like that :
'' => 0 clicks
'a1' => First click
'a2' => Second click
var right_text = '';
var step_counter = 0;
function countMe() {
step_counter++;
right_text = 'a' + step_counter;
document.getElementById( 'currentVal' ).innerHTML = right_text;
}
<button onclick="countMe();"> Click Me ! </button><br/>
<p id='resultText'>
Current Value : <span id="currentVal"></span>
</p>
