Create Header from Board

[NetMaster]

This is my first code. I made it from scratch. I've got everything worked out but how to call the array variables. Wormo, help please! Once it is complete I'll submit it to the Code Database on Support.

<script type="text/javascript">
<!--
//Create Header from Board
//by NetMaster

var titles =[
["Anti Welcome Board","Welcome to our Forum Spill"],
["Welcome Board","Welcome to our Forum Spill"]
];

if(pb_action == 'home'){
var awaytd = document.getElementsByTagName('td');

for(i=0;i<awaytd.length;i++){
if(awaytd.innerHTML.match(/'+titles+'/g) && awaytd.className=='windowbg2') {
awaytd.style.display="none";
awaytd[i+1].style.display="none";
awaytd[i+2].style.display="none";
awaytd[i+3].style.display="none";
awaytd[i-1].colSpan="5";
awaytd[i-1].innerHTML='+titles[i+1]+';
}
}
}
-->
</script>

are you trying to do the same thing as this code?

Sort of, except my version allows them to inject their own HTML instead of the Board Title.

[Wormopolis]

well you have the array defined all wrong to start

if you declare it as new Array(), then you would have to put in elements like

titles[0]='thing';


but since you want to do a multi-dimensional array you will want to use the more classic form

titles=[
[one, two],
[three, four]
];

[NetMaster]

Okay changed it in the first post.

[Wormopolis]

to access arrays, you need to use indices. titles.firstchild.value doesnt mean anything because titles isnt an XML object with a firstchild.

[NetMaster]

Okay. Do I need to include a new variable that runs a for statement for titles?

var match = for(i=0;i<=titles.length;i++) { titles };

[Wormopolis]

that line doesnt make any sense.

you need to have multiple indices if you are accessing multi-dimensional arrays.

Okay in this line here

if(awaytd.innerHTML.match(/'+titles+'/g) && awaytd.className=='windowbg2') {

I'm trying to get it to search through the array and match an entry to the innerHTML, but I don't have the right syntax: '+titles+'
Doesn't work.

[Wormopolis]

because titles in a multidimensional array. see my post above

[NetMaster]

Okay I am thinking a new way of set up for the multi-dimensional array so I can call all first entries only

<script type="text/javascript">
<!--
//Create Header from Board

title[0] = new Array("Anti Welcome Board", "This is the welcome to our forum part");
title[1] = new Array("Other Board","Other board info");

var titles = for(i=0;i<title.length;i++){title[0]};
var info = for(i=0;i<title.length;i++){title[1]};

if(pb_action == 'home'){
var awaytd = document.getElementsByTagName('td');

for(i=0;i<awaytd.length;i++){
if(awaytd.innerHTML.match(/titles/g) && awaytd.className=='windowbg2') {
awaytd.style.display="none";
awaytd[i+1].style.display="none";
awaytd[i+2].style.display="none";
awaytd[i+3].style.display="none";
awaytd[i-1].colSpan="5";
awaytd[i-1].innerHTML=info;
}
}
}
-->
</script>

[Wormopolis]

syntax error. i was not defined when you tried to access the multidimensional array of "title" to put values in "titles" and "info"

you cant really access dimensions of arrays like you are wanting. if you want to extract all the [0] entires from each entry in the array, you would need to do that with a for loop and a new array.

what you have in the first post is going to get you closer then what you just posted

[NetMaster]

<script type="text/javascript">
<!--
//Create Header from Board
//by NetMaster

var titles =[
["Anti Welcome Board","Welcome to our Forum Spill"],
["Welcome Board","Welcome to our Forum Spill"]
];

var rgx=new RegExp(titles[0],'g');
var rgx2=new RegExp(titles[1],'g');

if(pb_action == 'home'){
var awaytd = document.getElementsByTagName('td');

for(i=0;i<awaytd.length;i++){
if(awaytd.innerHTML.match(/'+rgx+'/g) && awaytd.className=='windowbg2') {
awaytd.style.display="none";
awaytd[i+1].style.display="none";
awaytd[i+2].style.display="none";
awaytd[i+3].style.display="none";
awaytd[i-1].colSpan="5";
awaytd[i-1].innerHTML='+rgx2+';
}
}
}
-->
</script>

[Wormopolis]

cant do regexp like

match(/'+titles[0]+'/g)

to do that, you will need to create a regexp object

var rgx=new RegExp(titles[0],'g');

[NetMaster]

<script type="text/javascript">
<!--
//Create Header from Board
//by NetMaster

var titles =[
["Anti Welcome Board","Welcome to our Forum Spill"],
["Welcome Board","Welcome to our Forum Spill"]
];

var rgx=new RegExp(titles[0],'g');
var rgx2=new RegExp(titles[1],'g');

if(pb_action == 'home'){
var awaytd = document.getElementsByTagName('td');

for(i=0;i<awaytd.length;i++){
if(awaytd.innerHTML.match(/'+rgx+'/g) && awaytd.className=='windowbg2') {
awaytd.style.display="none";
awaytd[i+1].style.display="none";
awaytd[i+2].style.display="none";
awaytd[i+3].style.display="none";
awaytd[i-1].colSpan="5";
awaytd[i-1].innerHTML='+rgx2+';
}
}
}
-->
</script>

I also tried this line:

if(rgx.test(awaytd.innerHTML) == 'true' && awaytd.className=='windowbg2')

instead of the

if(awaytd.innerHTML.match(/'+rgx+'/g) && awaytd.className=='windowbg2')
