[SOLVED] Webkit CRASH when calculating data from XML file

[michprev]

Hi,

I have problem with long function. On simulator it's working but on device it says:

This is my JavaScript file:

function prepocet(pole_meny) {
var select1 = shortcut1.text;
var value = value1.text;
var sum1 = 0;

switch(select1) {
case "USD":
        czk. kurz = Math.round(pole_meny[32]*1000)/1000;
                m6593.kurz = Math.round(( pole_meny[32] / pole_meny[0])*1000)/1000;

This function has 35 identical "cases" with different values​​.
I tried to set TARGET.EPOCHEAPSIZE = 0xF00000 0x2000000 but it doesn't work.

It's a guess, because I don't know if your variables like m6593, m6504 etc. are declared locally at the time they are used in that function and I don't know how your 'cases' differ from each other:

Try to split up your big function into 35 smaller functions, so that each small function handles one 'case'. This would also make the code cleaner. It could be (but I am not sure here) that then not so much memory is used, because a smaller function needs less symbols than the big one.

Maybe this link will help to understand the memory management when a function is called: "objects in javascript":http://stackoverflow.com/questions/3691125/objects-in-javascript

Let us know if this helps or not.

Yes, it's working. Thank you very much!
