Hi all experts,

I have a little javascript in which i change the source of a picture and resize it as well.

But on the browser i need to click 2 times. I would like it to be fully executed in 1 click.
On the first click it reloads the source.
On the second click it resizes the newly loaded source.



function picsourceresize(spimg){
    
    bigPic.removeAttribute("width");
    bigPic.removeAttribute("height");
    bigPic.src=spimg

    var orwidth = bigPic.width;
    var orheight = bigPic.height;

    var maxwidth = 600;
    var maxheight = 450;								

    if (bigPic.width/bigPic.height < maxwidth/maxheight) 
    {   
        var ratio = maxheight / orheight;
        var newwidth = orwidth * ratio;
        bigPic.setAttribute("height", '450px');
        bigPic.setAttribute("width",  newwidth+'px');	

    } else { 	
        var ratio = maxwidth / orwidth;
        var newheight = orheight * ratio;	
        bigPic.setAttribute("width", '600px');
        bigPic.setAttribute("height",  newheight+'px');					

    }

}

See if this js works  http://jsbin.com/ufixar/2/edit
function picsourceresize(spimg){
    
  var orwidth = bigPic.width;
   var orheight = bigPic.height;
    
  
    bigPic.removeAttribute("width");
    bigPic.removeAttribute("height");
    bigPic.src=spimg;

    

    var maxwidth = 600;
    var maxheight = 450;
     var ratio=1;

    if (bigPic.width/bigPic.height < maxwidth/maxheight) 
    {   
         ratio = maxheight / orheight;
        var newwidth = orwidth * ratio;
        bigPic.setAttribute("height", '450px');
        bigPic.setAttribute("width",  newwidth+'px');	

     } else {
         ratio = maxwidth / orwidth;
        var newheight = orheight * ratio;	
        bigPic.setAttribute("width", '600px');

Hi,

sorry for this late reply, i wasn't at my desk until now.

It is placed here:

http://www.judeco.be/Judeco/EEtest20130604.php

there are 2 links on there with 2 examples

With Firefox:
opening in the colorbox, need to click 2 times for script to work
rightclicking and opning in new tab, need to click 2 times for script to work


with Internet Explorer:
opening in the colorbox, need to click 2 times for script to work
rightclicking and opning in new tab, ONLY loads the new picture source not even resizing

Are you hand coding this?
Look at the two examples.  The bottom one breaks. It looks like it's not handeling the extra, "CngClassNP(bigPic)"

   <a href="#top">
                            <img 
                                src="stills/mo201209/thumbs/JS12-068.jpg" 
                                onClick="picsourceresize('stills/mo201209/JS12-068.jpg')" 
                                id="Pic5"  
                                alt="Pic5" 
                                border="0" 
                                width="60.136363636364" 
                                height="90" 
                            />
                        </a>
              			<a href="#top">
                            <img 
                                src="images/gshades/thZ8408-23.jpg" 
                            	onClick="bigPic.src='images/gshades/Z8408-23.jpg';CngClassNP(bigPic)" 
                                id="Pic6"  
                                alt="Pic6" 
                                border="0" 
                            />
                        </a>

Hi,

I just use a standard dreamweaver CS5.5 for coding

I don't understand what you mean when you mean the bottom one breaks.
If you mean there are missing brackets they all seem to open and close.

picsourceresize is the script not working in 1 click

CngClassNP seems to be working from the first click.




On both examples picsourceresize is for the pictures with backgrounds
onClick="picsourceresize('stills/mo201209/JS12-068.jpg')"

The far left, and far right picture-links (with white background)
onClick="bigPic.src='xxx.jpg';CngClassNP(bigPic)"
are just to reload and to remove any picture atributes

(on the second example there seems to be a missing thumbnail)

Hi,

I 've found the sollution.

So i've just put some alerts in between the codes to check if the height and width values werer passed thru from the beginning. And i was surprised that at that point it did execute in one click.

So i don't know why.

But splitting it up and putting a setTimeout in there fixed it.

onClick="bigPic.src='stills/mo201209/JS12-075.jpg';setTimeout(picsourceresize, 500)"

Regards,
