JavaScript - Too Much Recursion
hello every one , i'm new and i hoped u could help me with my code
I keep getting the same message "too much recursion" and i really don't know what is wrong , my friend and i codded the same way ,but it works for her not for me , here is the code : [merge sort algorithm] Code: var A=[2,999,45,23,17,879];
var B=[];
var C=[];
var i;
var j;
var k;
var x=0;
var mergesort_counter=0;
var merge_counter=0;
mergesort(A);
//=========================================================
//document.write( "<h2>mergesort</h2><p>", A, "</p>" );
function mergesort(A){
var n=A.length;
mergesort_counter++; //count mergesort calls
document.write( "<h2>mergesort</h2><p>", A, "</p>" );
var mid=Math.floor(n/2);
if (n>1){
for (i=0;i<mid;i++){
B[i]=A[i];}
for(j=mid;j<n;j++){
C[x]=A[j]; x++;}
mergesort(B);
mergesort(C);
merge(B,C,A);}
else document.write("the list is too short ");}
function merge(B,C,A){
merge_counter++; //count merge calls
i=0;k=0;j=0;
while( i<B.length && j<C.length ){
if (B[i]<=C[j]){
A[k]=B[i];
i++;}
else{
A[k]=C[j];
j++;}k++;}
if(i==B.length)
for (var l=j; l<C.length ; l++)
{A[k]=C[l]; k++;}
else for (var l=i; l<B.length ; l++)
{A[k]=B[l]; k++;}
document.write( "<h3>merge</h3><p>", A, "</p>" )}
Similar Tutorialsthis code: Code: $(document).ready(function() {
$('body').click(function(evt) {
if(evt.target.nodeName === 'A' && $(evt.target).hasClass('cross-link')) {
$('a[href=#2]').trigger('click'); } });});
gives me and error of "too much recursion" how can i solve this? Hi, can anyone tell me... Code: function Obj() {
this.recursiveMethod=function () {
//...how to invoke Obj.recursiveMethod from here?
}
}
Gus Code: function checkifischild(draggedElement,destination)
{
$getid = $("#" + destination).attr("class");
var __temp = $getid.split(' ');
console.log(__temp)
for(i = 0;i < __temp.length; i++){//for the length of the classes
if(__temp[i].match("child-of-"))
{//check if its a child
parent = __temp[i].substring(9);//get the parents node
if(draggedElement == parent)
{
console.log('yes');
return false;
}
}
}
checkifischild(draggedElement,parent)
}
i have the following function basically what it does it gets 2 parameters node-23,node-17 for example it finds the classes of node-17 and splits them up ["child-of-node-16", "initialized", "ui-droppable", "expanded"] ["child-of-node-19", "initialized", "parent", "expanded", "ui-droppable"] ["child-of-node-23", "initialized", "parent", "expanded", "ui-droppable"] so i compare each time the first parameter along with the substring of the child-of and if they are the same its returns false now my problem is if i call the function just like this checkifischild(node-23,node-17) it works i get in the console yes for example if i do this tho if(checkifischild(node-23,node-17) == false) it fails :? any ideas will be appreciated thxxx Hey im having a problem recursively calling my function. What I want to do is to change MyImages[0-14] with a timeout between them. Here is my code. Code: function swapImage(i) {
if(i < 15)
{
MyImages[i].src = "red_dot.gif";
setTimeout("swapImage(i+1)",500);
}
}
The problem is that it will only change MyImages[0] and MyImages[1] Hello I am trying to create a family tree, parents / grandparents etc, of a single person... My database etc is already working but I cannot find any working examples that I can make sense of... Each of my records has a name, dob and id of each parent.... How can I get X generations from this.. I thought something like this might work.. GetParents For each parent GetParents And so on... But I have no idea how to put this into code... Any suggestions to put me on the right line would be greatly appreciated Thanks Hi, I am having trouble with a recursive function I created to list out the indexes and values of various nested objects. Code: var macros={
CTRL: {
ALT: {
ENTER: "<br />",
P: "<p>.</p>",
A: "<a href=\"\">.</a>",
_1: "<h1>.</h1>",
_2: "<h2>.</h2>",
_3: "<h3>.</h3>",
_4: "<h4>.</h4>",
_5: "<h5>.</h5>",
_6: "<h6>.</h6>"
}
}
};
I want to print out the whole 'bread crumb trail' to each object, ie CTRL ALT 6: <h6>.</h6>, but at the moment my function prints out CTRL ALT twice for 'ENTER' and then never again. The function: Code: function printObj(obj) {
for(i in obj) {
var n=i.replace("_", "");
document.write(n);
if(typeof obj[i]=="string") {
document.write(":");
document.write(" "+obj[i].replace(/</g, "<").replace(/>/g, ">"));
}
else {
document.write(n);
}
if(typeof obj[i]=="object") printObj(obj[i]);
document.write("\n");
}
}
printObj(macros);
The current output: Code: CTRLCTRLALTALTENTER: <br /> P: <p>.</p> A: <a href="">.</a> 1: <h1>.</h1> 2: <h2>.</h2> 3: <h3>.</h3> 4: <h4>.</h4> 5: <h5>.</h5> 6: <h6>.</h6> Any advice would be appreciated. Cheers, Gus Well, I clearly haven't the experience with javascript to understand why I can't do this: Code: function bubbleSortKernel(a, b) {
if (b < 50) {
swap(a, b);
draw();
setTimeout("bubbleSortKernel(++a, ++b)", 200);
}
}
where Code: swap(a, b) does just what it says: swaps the two elements in an array, and Code: draw() looks about like this: Code: function draw() {
if (ctx != null) {
ctx.clearRect(0, 0, width, height);
for (var i = 0; i < rectangles.length; i++) {
ctx.fillRect(x, rectangles[i][0], rectangles[i][1], rectangles[i][2]);
}
}
}
I'm newer to javascript that other things, and this seems perfectly legal to me. I'm looking for someone who knows more that I and can explain what I'm missing. I'm guessing my timeout doesn't really work like I think it does, but I've gotten so frustrated I can't see the forest for the trees. Any help or nudge is greatly appreciated. Thanks! well, when i do this fucntion: function scroll(){ window.scroll(0,60) } i get a javascript error: Error: too much recursion well, what is wrong? what does that mean? how do i fix it? thanks for any help |
