A question to dust_dex

Your profile is not active so I'm can not know your name. I have a question ..

R Hartley

yes, I know. This is dusty_dex, logged in with an alternative email until my account is restored. I had a think about the lottery stuff, and wanted to ask you some more questions. How do you intend to store the lotto draws from the current week? Are the 2 lists (columns) only lucky numbers, or are the 6 numbers, actual *real* lotto draws that have taken place?

I have my account back now. Also changed my profile to allow email replies. :)

I wrote a simple random permutations, but May Have NaN Error Can help me with this?

dusty_dex

Off by one error - range of random 0-12, valid range for Array 0 - 11 Removed an unwanted comma (,) after rec[q] in your document write. :)

for(var i=0; i<12; i++) {
document.write(rec[i] + ",");
}
document.write("

Well.. now how do i prevent adding the numbers of array elements value, array elements only among themselves, I just wanted to combine random.. Output is: 19, 0 23, 1 20, 2 19, 3 34, 4 45, 5 it must be: 19, 23, 20, 19, 34, 45 Why does it wrote the numbers of random array and how do i prevent the same number selection..¿

Quickly remove the shameless

Hakan Bulut

I have to special thanks for all ur helps.

Hakan Bulut

I tried the following lines at least.. have you got an idea about this statement?

document.write("<BR><BR>" + "Combination is :" + "<BR>");
do(q) { z += 1;
var q = Math.round(Math.random()* 11);
if(q==q) {return q;}
document.write(rec[q] +", "+ z);
} while(z==6);

Hakan Bulut

Is there something to way some simple code to do this?

dusty_dex

Well you aren't putting the (value of) the z variable into the array. Only showing its value. remove the

+ z +" "

from document.write

replace with this.

var lucky = \[\];
var rec = \["19","20","21","40","41","45","12","23","34","36","37","46"\];
document.write("Weekly records for 2 week : ");
for(var i=0; i<12; i++) {
    document.write(rec\[i\] + ",");
}

document.write("

");

var z=0;
do {
    var q = Math.round(11 \* Math.random());
    if(!taken\[ rec\[q\] \]) {
        lucky\[z\] = rec\[q\];
        taken\[ rec\[q\] \] = true;
        document.write(lucky\[z\] + "

");
z++;
}
} while (z < 6);
</script>

this line:

if(!taken[ rec[q] ])

checks if NOT taken (! = not)

Just letting you know what your errors here are. See my other post for new code.

do(q)

can't use expressions at the top of do loop *(q)*, just use

do {

z is not declared with var *and* initialised with a value. var z = 0;

z +=1; // z (undefined) +1 is still undefined

you don't need the { } braces for a single statement..

if(q==q) return q;

but, q==q just evaluates to true so you might as well have just written this

return q; // if (q==q) {return q;}

I am not able to reply very quickly. On a training course for another 10 days. Be patient. Please keep trying to write new code as it is easier for me to guess what you are doing. :)

Excellent code thanks a lot.

Finally, ask you for anything more in a array of 12 elemented to 49 membered Argument want to match, you can also help me in this topic? JavaScript writing is so hard really. Thank you for your help. I tried the following lines:

var arrNumbers = [49];
var arrOutside = [];
var arrInside = ["19","20","21","40","41","45","12","23","34","36","37","46"];
var z=0;
for(var i=0; i<12; i++) { arrInside[i]=false; }

for(var j=49; j>0; --j)
{
arrNumbers[j]=j;

if(arrNumbers[j] != arrInside[i]) {
document.write(arrNumbers[j]=arrOutside[z], + ", ");
arrInside[i] = true;
z++;
}
}

if this is what special things I did not want to deal with it.. I do not want to discuss whom it is could not be shy

dusty_dex

Please explain what inside & outside mean. inside what? outside what? arrNumbers = [49]; // array length = 1 ??? I'm guessing this is what you intended arrNumbers = new Array(49); Also, you can't assign (=) inside of document.write()

arrOutside[j]=j

arrNumbers[j] = arrOutside[z]

did you mean to show arrNumbers and arrOutside, or copy from one to another? this does not make sense.

arrNumbers[j] && arrInside[i] = true;

What other programming language do you know? Because, it might be easier if you write your code in a computer language that you are familiar with. I will be able to figure it out.

It flags to the 49 numbers of numeric lotto arrInside is the numbers two week of and arrOutside is other numbers of 49 that is The number 49 is the number of remaining ..previously worked on the platform of Visual C++ 6.0.. I am thinking you are right JavaScript language is not completely literal a language because of it's called name as script ... arrInside arrOutside are instead of lucky or unlucky they may also like the your previous thread is to be
