How you might achieve the following without using eval()? I've come up a bit short:
function addOrSubtract(operator) {
var a = 10;
var b = 5;
var answer = eval(a + operator + b);
alert(answer);
}
addOrSubtract('+') // alerts 15
addOrSubtract('-') // alerts 5
I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

View 6 Replies View Relatedconsider the next code:
var obj = {};
with(obj) {
var x = 10;
}
print(x);
print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the
value 10. But it's not the case, because variable declarations are
placed at the start of function code (or global code), so the
previous code is equivalent with:
var obj;
var x;
obj = {};
with(obj) {
x = 10;
}
print(x);
print(obj.x);
You can clearly see now that x is placed in the outer context. But
consider the next:
var obj = {};
with(obj) {
eval("var x = 10;");
}
print(x);
print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it
gives the same output as the previous code. I tested it with
spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could
not find anything that describes that behaviour. Code:

I have this basic auto complete JavaScript that works well, but you need to hard code the web page. What I'm trying to do is send the "Autocomplete" variable data to the page using a perl script.the working JavaScript code looks like this:
var CustomArray=new Array('an apple','alligator','elephant','pear','kingbird','kingbolt','kingcraft','kingcup','kingdom','kingfish er','kingpin','SML');
Now the new code is: var CustomArray=new Array(Autocomplete);
And the Perl script is sending back the data to the browser looking like this:
var Autocomplete = 'an apple','alligator','elephant','pear','kingbird','kingbolt','kingcraft','kingcup','kingdom','kingfish er','kingpin','SML'

It gives me an undefined, right off the bat before any uploading, or anything at all takes place. I'm guessing this is because this value is set on page load, and not before the actual upload actually happens.
Does anyone have any ideas how I can set this value when the upload begins with the variable from the text file ? Keep in mind it has to be inside the function it's in now or it wont work.
Note that the loadXMLDocument function isn't called until the upload is complete, the .bind at the bottom of the page.
