Export to CSV/Excel for Chart – Infinite loop

Maya Shavin asked on January 31, 2017

Demo: http://jsfiddle.net/nz3zarh5/1/
There is a bug in the loop of checking if the table height is > 0 in the below code (flexmonster.js)
if (0 < c) {
for (;c < this.coords.In;) {
g = this.coords.Ir(h);
t = (e = this.grid.getCell(g, 0, !0)) && !e.Me && 0 == e.level ? ‘<tr class=”fm-first-level”>’ : “<tr>”;
this.showHeaders && (t += this.DM(g));
for (e = 0;e < this.coords.Tc;e++) {
r = this.coords.vn(e), t += this.mE(g, r);
t += “</tr>”;
c = this.n.height();
I think the assumption is that if the grid is hidden (table is not in view), its height is 0 and so it will never enter this loop. However, in case that the table has height set 100% in css (which will happens in a lot of cases of css customization) – the height will be 100 every time we ask for the height, and it will run in infinite loop and browser crashes.
It is critical bug. Please fix it.
