Filtering Lists Based On Variables?
Jun 19, 2011
I have a large e-commerce site that runs on a database. There are many products on the site which have 'variables' attached to them, e.g. colour, width, height etc. I have a script in place to sort the products depending on these variables Apologies for the length of the code.
(function(i) {var u =navigator.userAgent;var e=/*@cc_on!@*/false; var st =
setTimeout;if(/webkit/i.test(u)){st(function(){var dr=document.readyState;
if(dr=="loaded"||dr=="complete"){i()}else{st(arguments.callee,10);}},10);}
else if((/mozilla/i.test(u)&&!/(compati)/.test(u)) || (/opera/i.test(u))){
document.addEventListener("DOMContentLoaded",i,false); } else if(e){ (
[Code]...
I didn't write this script and I'm not a JavaScript expert, so i don't know how to edit it properly. I want to change it's function from sorting to filtering, i.e. something along the lines of a slice function.

I've got a variable that holds a jQuery object. I would like to filter out all of the visible elements in that jQuery object. The problem is once I'm using a variable and not the jQuery object itself I don't know the semantics for filtering it. I have something like this:
var Foo = $("#Bar");
FilterFunction(Foo);
function FilterFunction(Foo) {
var Test = $(Foo + ":visible");
}
What is the correct syntax?

I have a table with 1 row and 5 columns. I want to hide each column based on specific variables in the web page. Is there a way to do that. I tried a <div> tag and the below code, but it says you cannot put a <div> tag in a table etc.
Code:
document.getElementById('hiddenYearLeft').style.display = "none";
document.getElementById('hiddenYearLefta').style.display = "none";

I have 3 TextFields, called txtUSD, txtEUR, txtAUS. And a PopupList with the same values, minus the txt part, but I need to form the names of the TextFields to use based on the selection that the user made. So I've done this:
Code:
function btConvert_Click(event){
var amount = document.getElementById("txtAmount").value;
var rates = document.getElementById("lstConvertTo").value;
var from = "txt" + document.getElementById("lstFrom").options[document.getElementById('lstFrom').selectedIndex].text;
var to = "txt" + document.getElementById("lstConvertTo").options[document.getElementById("lstConvertTo").selectedIndex].text;
var curr_from = document.getElementById(from).value;
var curr_to = document.getElementById(to).value;
if(curr_from > curr_to){
amount * rates;
} else {
amount / rates;
} alert(result);
}
But every time I try it I get this error:
Code:
mobile/main.js line 215: Result of expression 'document.getElementById(from)' [null] is not an object.

I've got a PHP page that delivers MySql data into an HTML table for a To Do list. Works peachy. Now, I wanted to add a filtering tool to the table, which I've also done, and it works fine.
However, I'm dissatisfied with some of the methods I've used becuase they involve a bit of hard coding, and will make it difficult to expand on later down the road. I think you will see what I mean. There's a decent amount of code, but I want to include it all so that you may just copy>paste it and see the page as I do. Code:

I'm working this script below that successfully selects and removes certain anchors that contain this text "d2". There are actually numerous anchors in this TD (not div) container with different (labels for the site) text strings, each anchor is followed by a comma with a space.
So I'm removing the anchors no problem (thx to jQ) - but I still need help to remove the trailing comma and associated space after each anchor I remove. My attempts at this solution are so horribly naive I won't bother posting one.

I just can't seem to get getJSON to filter based upon the map I send in.
Here is my code:
$.getJSON('funds_static_json.dot',"{category:fundType}",function(json)
{
dropdownSet.loadSelect(json);
}
My post in firebug looks completely right: [URL] The json is formatted properly and passes the lint test. However, I get the entire json back and not the filtered by my parameter. I have over a thousand funds, but it should only pull back about 9 bassed upon that category. Here is my working url: [URL]

integrating PHP-HTML-JS I'd need some help for doing the following:I have a index.php including:
<script type="text/javascript">
function filter (phrase, _id){
var words = phrase.value.toLowerCase().split(" ");
[code]....
and a child.php including a table object with the id LIST.I'd need to change the parent.php in order to filter on real-time the table LIST via the FILT input on the parent form. I have tried different values instead of 'this' on the js function calling but nothing succesfully.

I use CMSMS alot and there is a drop down menu in the admin area to choose a parent item, it shows all parent items and I wanted it to be dynamic to just show top level siblings and children
I spent all day creating a jquery script to filter the list which works just fine in fire fox but IE does not support display:none on html option tags
My options are coloured white at the moment but it would be good if I could get them to disappear all together.
I have tried duplicating the object and using that as a reference and tried a global object but i could not get either to work
code below no jquery i am sure you have that already.
My code is probably a little sketchy my mind was blown after lunch.

Im using a jQuery script to show/hide a div based based on the selection made via a dropdown.
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
The problem im having is that the value used in the dropdown lists are price values eg 10.00
Consequently jQuery seems to interprit these as css notations, meaning the code doesnt work.

Given the following input tag which is enclosed within a hidden div tag:<input id="X" class="Y"/> this call (id-based) locates the tag: $(this).find("#X")but this one doesn't (class-based)I couldn't find any documentation indicating find() working differently when using id-based vs class-based selectors.

I have two select lists and depending on the value selected in the
first select dropdown, I want to populate the second list.
I tired a couple of different ways, but for some reason, it works fine
on IE but not on Firefox. On Firefox the second dropdown list doesnt
get populated.
Any pointers on how to populate the second dropdown..
Heres the code:-
for(var j=0;j<array.length;j++)
{
this.document.getElementById("secondSelectName").options[j] = new
Option("txt", "val");
}
for(var j=0;j<array.length;j++)
{
var oOption = document.createElement("OPTION");
secondSelectlist.options.add(oOption);
oOption.innerText = "txt";
oOption.value = "value";
}
for(var j=0;j<array.length;j++)
{
this.document.getElementById("secondSelectName").add(new Option("txt",
"val"));
}

I found a web page with 2 selection lists in a form. The contents of
the second selection list are updated based on the entry in the first
selection list. For example:
if the first selection list has all the states in the USA, the second
list will display all the major cities in the selected state.

I have this code in the beginning: document.write("<option id='test' value='move" + i + "'>Fire Blast</option>");
How do I edit the text Fire Blast to something else? The Fire Blast part is not attribute, so it can't be edited like:
document.movelist.name = "Something else";

I've tried w3schools, tizag, and google, but haven't found exactly what I need. I need some way of easily figuring out which option in a drop down menu is checked, through the use of javascript, like how you can use document.formname.elementname[i].checked to find out which checkbox/radio button is checked. Anything that would return something that allows me to figure out which option has been chosen. I will need to have a function with 3 if statements, one for each option.
