De-constructing A String Into Several Variables

Apr 1, 2009

I have a string that I want to de-construct into several variables. I know I can use Indexof and Slice to do this but was wondering if there is something similar to Indexof that will give me every position of the separator. I know that the separator will always occur a set number of times in the string.

Using Variables In A Document.form.value String

Jul 23, 2005

I have a PHP page generating a list of items. I've made it so that
each one has a radiobutton with a unique value. You can click on the
radiobutton and it will change the value of a text field to the value
of the radiobutton--all that works fine!

Now, I need to also have it populate a textfield with the value of a
textfield in the row that's selected.

I can make unique field names, no problem. I think my problem is
getting the javascript written so that it recognizes the variable.

Well, see below. As it's written below, the textfield "itemqty" always
has the value "NaN" (wherever THAT comes from) no matter which
radiobutton I select.

Dynamic Query String Variables?

Sep 20, 2007

I'm working on a rather complex booking system for building European
trips, in a combination of SQL/VBScript/Javascript. There are tons of
query string variables that get passed back and forth between the
pages, and in almost every case, I can set 'em up fine, provided the
variables are in the link.

The page the *holds* the booking information, though, is problematic.

An example trip might include two European cities or towns with a week
in each in an apartment or cottage that the user selects from a dozen
or properties for each region.

All the information is on one page (all the dozen or so properties for
each weeks, available dates for the trip and for each , max occupancy
per property, pricing per property and per number of passengers,
etc...everything necessary to actually book the trip). If the user
changes party size or chooses a date, properties are hidden or shown
depending on max occupancy and/or availability.

So, a user sets their date and party size (or maybe just the party
size, or maybe has just cleared everything out to start over...) then
wants to view available properties so they can find one they like. The
current pax/date/etc. information is not in the query variables,
because the link was built at runtime.

If I build the link in an onclick event, it breaks if someone right
clicks to open a new page or tab.

I hate sites that disable right click menu. I hate sites where, when
you open a new page with a right click, it generates a javascript
error if the URL is created with an onclick event. I hate that using
an onclick to bring up the page means whatever is showing in the
status bar bears no resemblance to the page that is brought up when
you click on the link.

My client isn't worried about the non-javascript people for this use;
those people are referred to a free spiffy catalog, which frankly, is
how most of this client's customers book their trip anyway. I just
want to be able to carry the variables in such a way as to not break
the site if someone right clicks.

Anybody have any suggestions? Is it hopeless?

Parse Search String Into Get Variables

Aug 21, 2002

I feel like I have been repeating this code lately, so I cleaned it up and am gonna show it here. This function returns an array (with hash names) containing all the get variables.

function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}A simple page to test this looks like<html>
<head>
<title>Test</title>

<script>
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}
</script>
</head>

<body>
<script>
var g = parseGetVars();
for (var i in g)
document.writeln(i+'='+g[i]+'<br>');
</script>

</body>

What is stopping my code from displaying the time, date, and greeting from my stored variables?[code]...

I also tried placing paragraph tags, "", and '' ,respectively, inside the parenthesis as well as using '+variable+' instead of " . variable . "

The word "blah" was used to make sure the marquee tag was supported by browsers I have used to test this. So far I have only run into trouble with my document.write(stuff) not being displayed.

Problems Generating Javascript String Variables With Php..

Feb 14, 2005

i'm trying to create some javascript string variables using php. i'm running into a problem because some of the variables span multiple lines and this is causing a problem. here is a sample of what i'm trying to do:

var thetext1=new Array()
thetext1[0]="info for #1 goes here"
thetext1[1]="info for #2 goes here"
thetext1[2]="info for #3 goes here"

etc.... the array values are output from a mysql db using php and used for a script i have on my page.

the problem is some of my strings span multiple lines and end up making it look like:

thetext1[36]= "this is an example
of how some stuff spans
multiple lines"

Using the javascript console in firefox i see the problem is: "Error: unterminated string literal." I believe it is because the string I am trying to input is spanning multiple lines. any idea on how to fix this?

i'm using php/mysql to create these javascript variables so i have access to their functions. i tried doing this:
str_replace( "
", '', $row['text']);
to replace the newlines with nothing but they're still there.

any ideas on how to get around this?

JQuery :: How To Concatenate Text

Nov 18, 2009

I've tried various methods but haven't had any luck as of yet. I'm returning a series of 4 objects via AJAX calls. When each object loads, I'd like to iterate through it (no problem), and populate the "value" attribute of a hidden input field with each value from the object. I can't seem to find a way to intermingle jQuery and '+=', or find a jQuery substitute.

Concatenate Dynamic Variable Names

Jul 23, 2005

I have a table that I populate with an array using ASP. As each row is created, the form object names are appended a numeric, such as:

i = 1
<select name="select<%=i%>">
...
...
...
i = i+1
next

I then pass "i" to a javascript function, so that I can access the values of each form object. I can't figure out how to properly concatenate the "i" and still allow access to the value in the form object. Currently I have:

var ps = 'platSymbol' + I;
alert(ps)
var sel = 'document.frmUpdPlatGrp.' + ps + '.value'
alert(sel)

I know I'm wrong, as this comes back as a complete string. Ultimately I want to have something like this:

var s = document.frmUpdPlatGrp.platSymbol2.value - so that I can actually get the value.

Substring A Value For Display And Concatenate For Validation?

Feb 28, 2006

I have a validation script for upc codes which is currently working for
values that are entered into one text box. I've been asked to break up
the text box into 3 separate fields to accept the 1st digit, middle 10
digits, then last check digit. What I'm doing is substringing the
initial values then concatenating them. What I'm not sure of is, how to
handle the validation. I was previously firing an onBlur after the text
box but now that I have three, and I need the values to concatenate
into one for the validation. Should I just fire a function after the
3rd field that concatenates the 3 values, then pass that value to the
validation function? Or is there a better way?

I was also wondering if there was something I could find like an input
mask, but something that could just "overlay" on top of a regular text
box with one value which could give the appearance of having
separations for certain digits, in this case the first and last.
