Parsing Through CSV To Get Specific Name/value Pairs?
Oct 2, 2010
I have a task that could be made much easier if I built a simple tool to parse through a CSV data pasted in a text area and it spits out specific the parts the name/value pairs I need. I do not have the luxury of a database and the data is a bit sensitive or else I would not be needing your fantastic assistance and I would have churned out some server-side magic.Anyway, what is tripping me up is the necessity for regular expressions (and my lack of experience in this area in general), which can drive a man to drink. I can work with the code to get the specific parts I need and manipulate what is spit out to my specifications but its the starting point that I need help with.
I pasted a sample section of the data I need to parse through.I am pretty sure I can work with the data once it gets split into an array that can be searched through.
I'm trying to write a little Javascript that would parse a CSV file that contains a name and date, and only display the name if the date matches today. Here's some example data:
If today were 6/10/2010, the output of the script would just be "Joe"

let me say up front that my experience with JavaScript and "Ajax" interactions has been horrific. There are weeks I will never get back because of it. Whenever I encounter something so horrific that it makes me blank my memories of the event, I find myself going back and trying to take different approaches to understanding what happens.
This current round of experiments involves sending and receiving what is effectively an associative array. That is, I want to send dom names and the associated values via XMLHttpRequest calls and on return, get a set of dom value pairs and push them back into the current environment in the browser.
what I need to figure out how to do is associate a series of DOM's with a button, extract the information when the button is pressed, and then present the entire array to a CGI. On return, I would need to take the same array from the CGI and transfer the contents into the specified DOM's
if this is not practical, tell me so and I go do something else which is probably more fun. If it is practical and has been implemented in some toolkit, fantastic. It saves me some pain. If it hasn't been implemented, well, there goes the more hours that I will never get back.
<select> <option value='a' > First <option value='b' > Second <option value='c' > Third </select>
Is there a way I can access the values First, Second and Third from an array ? I want to write a javascript function that can automatically select one option based on a regular expression match of First Second or Third.
...which suggests my JavaScript is partially working, but is failing on my attempt to make Key/Value pairs. Unfortunately, I'm not knowledgeable enough on JavaScript/DOM to identify an error and would be grateful if a more seasoned programmer could let me know the error of my ways.
I'm trying to figure out how I can create javascript code in a bookmark that pulls the names and values from the form inputs in a loaded document.In addition it would also be nice if the code knew which form has focus and just pulled the input names and values from that form.I've been trying to figure it out, but the only portion I could get to work so far is:
Code: javascript:(document.write(document.forms[0].elements[0].name)) I don't really know where to go from here. Writing javascript in a javascript:() seems to be different and beyond my level.
Whenever execute the following code, the URL that is formed has "?" before my name and an "=" before my value (so the URL would be "[URL]"). I need the URL formatted so that a "+" is in front of the name and a ":" (colon) to be before the value (i.e. formatted like "[URL]"). Is there a way to change this behavior? $.ajax({ url: lansaUrl('proc', 'func'), global: true, cache: false, type: "GET", data: ({"acct": object.value}), dataType: "json", success: function(result){ $("p#customerInfo").innerHTML += " "+result; }, error: function(xhr, desc, exceptionobj) { alert(xhr.responseText); }});
Basically I want the field name to be a variable but it is taking it as a literal.When I print back the POST array with PHP I get:- Array ( [field_name] => Whatever I typed )So if the text field has a name of 'username' then I want the PHP to print back
Array ( [username] => Whatever I typed )
$(function(){//on DOM.load $('.register-field').blur(function() { var field_val = $(this).val();
I suppose I should somehow loop through all the labels, and for each find the next input. Then make a selection of this union and apply a wrapAll('<div class='field'>) But how exactly do I do this using jQuery manipulators?
I'm not sure if I'm calling it the right thing, but I'm trying to dynamically create a bunch of key => value pairs in a javascript object.
Something like this:
Code JavaScript:
But the console gives me errors, and I haven't been able to find a way to do this. I've tryed putting the keys in square brackets, as was suggested somewhere online, but that didn't work.
I need to have this setup as a client side cookie (javascript disabled - no problem).
I need to store in the cookie page name, first name and last name (and there are about 4 more items). Should i save a different cookie for each item here (all javascript examples show this) or can i do some thing like this?
What is happening is $(this) is no longer based on .expand being the (this) that is clicked.
like if i have a button SOMEWHERE randomly on the page with this
<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.
Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??
just like the .expand click function I posted on the top of the post that works?
Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.
I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.
Is there a single method using JS that works for all browsers?
function result(){ var result = document.getElementById('resss').innerHTML; }
But what I actually want is to import data from a table of an external website. E.g. I want to get the innerHTML of a specific cell in column 3 and row 2 of a specific site.
i have an ajax script that requests data from a database. Some of the fields contain html. I would like to know the easiest way to parse an xml file that looks like such:
<response> <poster>Poster name here</poster> <title>Title goes here, may contain a link</title> <text>html content here</text> </response>
i can't seem to figure out an easy way of parsing all the contents between a tag, what is the easiest way? I'm trying to fix a script that doesnt work when the text area contains html and i can't get it to work.
My problem is that i need an algorithm parse parse HTML. For an HTML page, my script has to parse all tags to get all forms values, even if there is frame, iframe, ... How can i do such a script ?
The code works OK in Firefox and Google Chrome, but it fails in Konqueror (khtml) or IE 8.0: the resulting array is empty although the xml read by Ajax call is OK. I tried also with "$("tagname", xml).each()" - same result.
I'm trying to work with XML DOM for the first time as I need to grab a value from a SOAP request. I've been following this: [URL], which says modern browsers won't parse xml files from another server for security reasons. How would I got about doing this then? I've been using the price of crude oil as an example [URL] and want code portable enough to put on something like Tumblr, so I don't think I can actually save the file locally first.
I am trying to split an IP address into it's 4 octets using a RegExp and assigning the result to an array but it is not working. Here is my function so far:
<script type="text/javascript"> function lastoctet(ipaddress){ var ipoctets = new Array();
I have a project coming up this summer that will include having to run a quiz like application from several machines disconnected from the internet.
I was hoping to be able to have all of the quiz data in an XML file and the actual quiz page as html/js. The machines will be using IE5/Mac.
Unfortunately, I won't be able to get a hold of a machine for testing until very close to the deadline, so I need to know what technologies will and wont work for the browser. What kind of compatibility issues (if any) should I be weary of?
