Infinite Loop In Certain Cases

[excelsystems]

In my application content of the page which contains Fusion Chart is reloaded multiple times with AJAX request, so chart is regenerated several times which at some point causes infinite loop ONLY IE 7.

I've tracked down problem to the code of the function "global.normalizeCSSDimension" and particularly:

--

 

 

if (w.match(/^\s*\d*\.?\d*\%\s*$/) && !w.match(/^\s*0\%\s*$/) &&

container.offsetWidth === 0) {

while ((p = container.offsetParent)) {

if (p.offsetWidth > 0) {

w = (p.offsetWidth * parseFloat(w.match(/\d*/)[0]) / 100).toString();

break;

}

}

}

 

if (h.match(/^\s*\d*\.?\d*\%\s*$/) && !h.match(/^\s*0\%\s*$/) &&

container.offsetHeight <= 20) {

while ((p = container.offsetParent)) {

if (p.offsetHeight > 0) {

h = (p.offsetHeight * parseFloat(h.match(/\d*/)[0]) / 100).toString();

break;

}

}

}

--

 

The problem is that offsetHeight and offsetWidth can be 0 at the very beginning which will cause these loop never end.

I've fixed it by modifying code like this:

--

 

if (w.match(/^\s*\d*\.?\d*\%\s*$/) && !w.match(/^\s*0\%\s*$/) &&

container.offsetWidth === 0) {

if ((p = container.offsetParent) && p.offsetWidth > 0) {

w = (p.offsetWidth * parseFloat(w.match(/\d*/)[0]) / 100).toString();

}

}

 

if (h.match(/^\s*\d*\.?\d*\%\s*$/) && !h.match(/^\s*0\%\s*$/) &&

container.offsetHeight <= 20) {

if ((p = container.offsetParent) && p.offsetHeight > 0) {

h = (p.offsetHeight * parseFloat(h.match(/\d*/)[0]) / 100).toString();

}

}

--

it would be great if this issue will be fixed in the next versions of Fusion Charts

Hi,

 

In what FusionCharts version you are facing this issue? please mention the version details.

 

Also, can you paste your sample code here?

[excelsystems]

@version fusioncharts/3.2.3-sr1.5347 but it also does not work in 3.2.1

 

Unfortunately I do not have example because it is a part of a huge system, but original code looks dangerous and I happen to hit the case when it fails.
