How to use variables in document.evalua te()

Hi all:
I met a problem when using document.evalua te() to get text content
using XPath,
my code is as follows:

nodes = document.evalua te("/html/body/div/ul[1]/li[5]", document,
null,XPathResul t. UNORDERED_NODE_ SNAPSHOT_TYPE , null);

in the XPath expression "/html/body/div/ul[1]/li[5]", I need to
traverse from li[1] to li[5],
so I should use a variable here , like this:

for (index =1; index<6; i++)
{
nodes = document.evalua te("/html/body/div/ul[1]/li[index]", ....);
// the variable index here is invalid!
}
my question is: How to use the variable in XPath expression?
appreciate your help!

Hi

You may be confusing this with something like PHP which does allow you
to reference a variable within a string literal.

In JavaScript it should be

nodes = document.evalua te("/html/body/div/ul[1]/li[" + index+ "]",
.....);

Regards

Julian

Hi, can anybody put forward a sensible argument javascript's behaviour of creating a new global variable whenever I assign to a previously undeclared variable. I can't beleive this is just for the sake of convenience (surely we learned this much from basic). here's my proposal: all "global" (document scope) variables must be declared by 'var' outside a function block.

I'm learning Javascript. I downloaded a script for study. Please tell me how the variable "loop" can have scope in the first function when it is altered in the second function? It is not defined in global space, therefore it is not a global variable, yes? Even if it was global, how would it get from one function to another? In PHP variables are copied by value. Are they copied by reference in Javascript? <SCRIPT LANGUAGE="JavaScript">

http://www.JavascriptToolbox.com/bestpractices/ I started writing this up as a guide for some people who were looking for general tips on how to do things the 'right way' with Javascript.

The above URL is version 1.0 (draft) that resulted. IMO, it is not a replacement for the FAQ,...

In Firefox 1.5 (this question is Mozilla specific as I am using greasemonkey) I would like to be able to use document.evaluate to return the first TD entry that shows ^\s*MySearchText\s*$. As I understand it, xpath doesn't yet have regular expressions so I thought to do: function findNode (srch) { var node; var expr="//td"; var RE = new RegExp("\\s*" + srch + "\\s*$");

Is there a way to tell whether accessing a variable will result in an "Undefined variable" E_NOTICE? isset() almost does this, but it also returns false if a variable is set to null: $SetNonNull = 0; $SetNull = null; var_dump(isset($SetNonNull)); // bool(true) $Junk = $SetNonNull; // No error, as predicted by isset(). var_dump(isset($NotSet)); // bool(false)
