Use of "function open_win" on frame pages

@ZeroKilledOct 11.2008 — #first mistake you should understand, very important. whenever you give two or more thing the same indentifier name, the last readed statement overwrite the previous; that apply for everything: object, function, variable. that is:

<i>
 </i>var [COLOR="YellowGreen"]num[/COLOR] = 0;
 function [color='yellowgreen']num[/color](){}
 alert(num);

notice the identifier ([color='yellowgreen']green color text[/color]) are the same. since they are the same, function [B]num[/B] overwrite the variable [B]num[/b], hence the value of variable [B]num[/B] is lost. in your case, the second function overwrite the first. there is various solution, some aren't good practice and some are better to mantain. you can give different identifier to each function or you can have one function for all of them and simply pass as parameter the url you want to open.

second, according to your topic you're trying to load documents on frames, not on new windows. [B]window.open[/B] is solely used to open new windows, not to change the frame's url. you have to refer to each frames so you can change their source and that might be according on how they are nested. i will assume you have a simple nesting. a document that hold three frames: a header, a menu and the main content.

[code=html]
 <frameset rows='200, *'><frame src='header_path' name='header' />
 <frameset cols='200, *'>
 <frame src='menu_path' name='menu' />
 <frame src='content_path' name='content' />
 </frameset>
 </frameset>
 [/code]

assuming that link from the menu frame will update document from header and content frames, javascript code is:

<i>
 </i>function frameUpdate(parentSource, mainSource){
 parent.header.src = parentSource;
 parent.content.src = mainSource;
 }

[code=html]
 <a href='document.htm' target='content' onclick='frameUpdate("/header_source.htm", this.href); return false;'>link</a>
 <a href='document.htm' target='content' onclick='frameUpdate("/header_source.htm", "/other_document.htm"); return false;'>link</a>
 [/code]

this sample show two different way you can use the function [B]frameUpdate[/B], you can pass a literal string or the string from the current link href attribute.
