Hey guys!
Another day, another Problem.
While programming my gallery I've stumbled opon some very strange problems.
To get a better view into the execution of my code I've "written" (copy and paste) a pause function.
Now I think I might have found my troublemaker: my sourcecode seems to run backwards!
With "pause" I've found these problems / this problem:
Here is a short part of my code that troubles me:
What my code should do:
Now my code does what it is supposed to do:
If I chance the order of my code to:
$(document).ready(function()
{
$("#thumbs img").click(function()
{
alert ("hi there!");
$(".vor").text("Test");
pause (3000);
});
});
It does:

With "pause" I've found these problems / this problem:
Here is a short part of my code that troubles me:
- function pause(milliseconds)
{
var dt = new Date();
while ((new Date()) - dt <= milliseconds)
{
/* do nothing */
}
}
$(document).ready(function()
{
$("#thumbs img").click(function()
{
$(".vor").text("Test");
pause (3000);
});
});
What my code should do:
- Overwirte the text in $(".vor")
- Wait for 3 seconds
- Wait for 3 seconds
- Overwirte the text in $(".vor")
The lines get executed in the wrong order, but thats not all:
I get realy weird results when using alerts:- $(document).ready(function()
{
$("#thumbs img").click(function()
{
$(".vor").text("Test");
alert ("hi there!");
pause (3000);
});
});
Now my code does what it is supposed to do:
- Overwirte the text in $(".vor")
- Greet the user with a friendly "hi there"
- Wait for 3 seconds
If I chance the order of my code to:
$(document).ready(function()
{
$("#thumbs img").click(function()
{
alert ("hi there!");
$(".vor").text("Test");
pause (3000);
});
});
It does:
- Greet the User
- Wait for 3 Seconds
- Change the text
so the order in wich $(".vor").text("Test"); and pause (3000); are executed are swapped again.
I am totally confused why that is...
Can someone please help me to understand this behaviour, thank you very much!
