JavaScript - Search Text, Csv Other File
I'm pretty much lost at javascript, and unfortunately can use php to accomplish this, so here goes........
I have existing html page that includes a Week #. ie, 1, 2, 3, 5.... and so on. I'd like to be able to have a text, csv, or similar file that I can update on frequent basis that will list a Week # and than custom field of some type. (likely a date or unix time stamp). Is there a way to open a text file (or csv, etc) in javascript. Than be able to compare and get the correct data? Off the top of my head, I think its possible, and would involve something like the following? 1. Create a csv file like below 1, this is custom, my other custom 2, some more, and this too 3, and somthing, see spot run 2. Next would be have a javascript open and read the file. You would assign a variable name to each 1st, 2nd and 3rd item of each line. Than the script would loop through each line until it found a a match of Variable 1 to the Week your looking for. You could then parse out and use the other variables from that line. Any of that make sense? I hope to try and experiment some later today or tonight if I can, but javascript is still pretty foreign to me. Similar TutorialsI'm having major pains trying to figure this out. I'm kind of new to Javascript, I need to open a text file from an external server, store each line in an array, then search that array for a certain word (HIGH), and if it exists then write something to the webpage, and if not, write something else. Here is what I have so far: Code: <html>
<head>
<title>Test</title>
<script>
<!--
function test(x) {
if (wxd1txt.readyState === 4 && wxd1txt.status === 200) { // Makes sure the document is ready to parse and Makes sure it's found the file.
var wxd1text = wxd1txt.responseText;
var wxd1array = wxd1txt.responseText.split("\n"); // Will separate each line into an array
var wxd1high = wxd1array.toString(); //Converting the String content to String
//var highsearchreg = new RegExp("HIGH");
//var wxd1high = wxd1array[x].search(highsearchreg);
document.write(wxd1high);
if (wxd1high.search("HIGH") >= 0){
document.write("HIGH RISK");}
else {
document.write("NO RISK");}
}
}

When added to a webpage, nothing shows up except the "Hi!" and there are no errors in the Javascript Console in Google Chrome. Is this possible with Javascript, and if so, what am I doing wrong or not doing? Also, I have 2 URLs, one is a text file that has the HIGH text I want for an example, the other is the current file, which shouldn't have HIGH in it (unless the weather in the US turns really bad) Hi, I am creating a Search functionality program, which searches a file mentioned by the user on a folder present in a Network folder through File Scripting Object. The code works fine but the problem is that, when it searches the file on the Network folder the entire HTML page gets hanged and nothing is displayed till the code has finished searching. I want to update the user with the status of the search process as which folder is it currently searching just the way we have it in the Windows Serach functionality, where the progress is shown on the left side of the window and the files found is shown on the right. I have tried the solution with having two different frames where the first frame will have the HTML and the JavaScript code to search the file and it will also write the results in notepad file as soon as it gets a matching file name and then proceeds ahead. The other Frame will read that notepad file and display the data and it will also refresh itself in every 2 seconds. But the page still hangs up since the first frame is not responding. I have tried the same solution by having two separate HTML pages instead of two frames but no luck. The new HTML page and the previous page both hangs up. Any Ideas?? I'm working on a site built through Squarespace, and I've run into some limitations. They've told me it's possible to build a Javascript to pull specific images from one page's journal entries and place them (with links to the entry) on other pages. Can somebody send me in the right direction on how I would do this? Basically I want to find a most recent posting tagged with a specific category, find the file file path of it's related image, and make that appear on the page that my javascript is on. I have around 100,000 html files that I need to do a search/replace on. I currently have the word "Manchester" in all of these files which needs replacing with the full file path location; C:\Demo_Folder\Manchester_file_001.html C:\Demo_Folder\Manchester_file_002.html Your help would really help me sort out my mind blowing task I've been given. Thanx in advance SuperZ This is a follow up to my older thread, about tables and finding images within them. So after getting some help from "Krupski" I found myself stuck again. I'm trying to go at this rather from an other point of view, instead of getting the cell information I am now trying to get the alt text value. from within the image tag. but being a novice at this well ive hit a wall. My code so far. searches though the table finding the sad images then i want it to display the Alt-text or an other value table_id or similar. also is there a fast way of putting in Alt text like A1,2,3 B1,2,3 etc like an automated loop. (might work on this after the main problem is dealt with) Code: <html>
<head>
<script type="text/javascript">
var findImg = function(name) {
var e = document.getElementsByTagName('img');
var i = e.length; // how many img elements total
var str = '';
while (i--) {
if (e[i].src.indexOf(name) != -1) // if match...
str += e[i].src + '\n'; //...copy to str with a newline
}
alert(str); // display all matches
}
function searchFor(){
findImg('smiley%20sad%20Icon.jpg'); // call the function with the name to be matched
}

Thanks in advance anyone who can help. ~Mark j Sorry, not sure if I need Javascript for this so I posted it in the html forum as well I'm looking to create a simple page where a user can copy and paste a list of ingredients and then push a button to search that list for a number of key words. Key words: Amodimethicone, Trimethylsilylamodimethicone, Glycerin, Trideceth-12, Behenoxy, Bisamino, Aminoethyl, PG-Propyl, Phenylpropyl, Methicone, Cyclomethicone, Cyclopentasiloxane, Cyclohexasiloxane, Cyclopentasiloxane, Dimethiconol, Trimethylsiloxysilicate, Silicate, Siloxy, Trimethylolpropane, Diisostearoyl, Copolyol, Dodecylbenzenesulphonate, Diphenyl, silicone, Methicone, Simethicone, Trisiloxane, sulfate, Myreth, Lauryl, Laureth, Sulfonate, dodecylbenzenesulfonate, Xylenesulfonate, Ammonium, Isethionate, Sulfoacetate, Sarcosinate, Sulfosuccinate, Carboxylate, Taurate, glycinate I don't care how they are alerted if any of the key words match their ingredients pop up, highlight, whatever. *Incase anyone is wondering it is to search hair products for any form of silcones or sulfates since many people wish to avoid them but they come in many different forms. Thanks!! Hi, I am having trouble searching for text in a textarea in all browsers. I display formatted text in a textarea with tinyMCE editor. Some of the text contains blanks ('______') which the user needs to find and fill in (usually with a number). I have written a new button on the toolbar of the editor which will find and highlight the blank when clicked. The user will click the button, fill in the text, click the button, fill in the text, etc. In IE the blanks are highlighted just fine. The only problem is: user clicks button and first blank is highlighted. User fills in the text then clicks the button again. Second blank should be highlighted but it skips right to the third blank. If you don't fill anything in, the next blank will be highlighted. If you highlight and then fill anything in, the next blank is skipped and the following blank is highlighted. Any thoughts? But my worst problem is with Mozilla. I get an error. It does not act like setSelectionRange(pos, pos+len(str)) is a valid function call. I receive the following error: "component returned failure code: 0x800004005 (NS_ERROR_FAILURE)[nsIDOMNSHTML TextareElement.setSelectionRange]" Here is my function: var win = window; var n = 0; var str = '______'; function FindBlanks() { var txt, i, found; win = tinyMCE.get('txtPolicy').getDoc(); if (str == "") return false; if (window.execScript) { txt = win.body.createTextRange(); //Find the nth match from the top of the page for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) { txt.moveStart("character", 1); txt.moveEnd("textedit"); } // If found, mark it and scroll it into view if (found) { txt.moveStart("character", -1); txt.findText(str); txt.select(); txt.scrollIntoView(); // n = i--; n++; } //Otherwise, start over at the top of the page and find first match else { if (n > 0) { n = 0; alert("End of document has been reached."); } //Not found anywhere, give message. else alert("No blanks found."); } } else { //document.getElementById('txtPolicy').setFocus; var ht = '______'; if (ht.length == 0) { alert('highlightText has zero lenth'); return false; } var str2 = document.getElementById('txtPolicy').value; var startPos = str2.indexOf(ht); if (startPos == -1) { alert('No blanks found'); return false; } document.getElementById('txtPolicy').focus(); document.getElementById('txtPolicy').setSelectionRange(startPos, startPos + ht.length); return true; if (n == 0) alert ("No blanks found."); } return false; } Can anyone help me with this? Thanks. Hello, I have this search box form with 2 select boxes : Code: <form action="search.php" method="get"> <select name="RingType"> <option value="Nose">Nose</option> <option value="Toe">Toe</option> <option value="Belly">Belly</option> </select> <select name="NecklaceType"> <option value="gold">Gold</option> <option value="diamond">diamond</option> <option value="pearl">pearl</option> </select> <input type="text" size="60" name="keywords" /> <input class="submit" type="submit" value="Search" /> </form> For example, when a visitor selects "Belly" RingType, I want "Belly Ring" to appear in the search box. and when the visitor selects "pearl" NecklaceType, I want "pearl necklace" to appear in the search box. if the visitor first selects "Belly" RingType, and then selects "pearl" NecklaceType, I want "Belly Ring pearl necklace" to appear in the search box. After making his selections in the search box, if he types something in the search box, it should add to what is already there in the search box. Or, if he first types something in the search box for example, "jewelry" and then selects "pearl" in the necklacetype select box, the search box should show : "jewelry pearl necklace" Can you please show how to do this ? Thanks a lot. I would like to ask is it posible to add text from a text file to a text area on a page..

Hello, I am building a web application that has quotes on it. I am planning on having all the quotes stored in a .txt file. A line space would separate the quotes. Example: "Blah Blah" "Idk what blah" "sure you do" Would this be using Javascript to pull the quotes from the txt file for use in my page be best? I need it to pull all the quotes. Reason for having it like this, I am also planning on having a random quote page where it just pulls 1 quote instead of showing all of them. I'm also open to other ideas here! David Faircloth Is there any possibility to write a text file using Chrome/FF? On the other words, writing a text file w/o using ActiveX. Thank you.

Have you any other way with pure js to read the file contains ? or allowing activex in all browser ? Somebody had posted this query on how to read text files using JavaScript.......can't find that post now... Anyways, though it's not possible to read text-files using JavaScript it is possible to read XML files using it. Here is an XML based JavaScript Ticker http://www.dynamicdrive.com/dynamicindex2/xmlticker.htm It works only on browsers supporting XML (IE) Enjoy! Hi all, How can i read CSV data from the text file using Java Script.Please give me the script for the problem. Thanx, Nari I have the ability to remotely upload a text file to a folder on my web server. Periodically during the day I update that file and re-upload it which overwrites the previous file. I am looking for a script to insert in a webpage that will "get" and display the current version of that file on page load. Thanks in advance. Im trying to use javascript to search a text file. text file is like this... 1111111[TAB]Project Name[TAB]Application1 2222222[TAB]Project Name[TAB]Application2 Im trying to get the javascript to let a user search for number or project name, if found it displays all the info if found. application1 or application2 (whatever is in the 3rd area) The text file can also be seperated by commas, either way is fine. can anyone help with this. ? Hey guys, I'm writing a script and I've encountered a problem.. I have a txt file with many words, each word in a different line. For example: the file words.txt contains: word1 word2 word3 word4 word5 I need to load the content of the file into a variable in my script. I prefer that all the words will be in the same variable with line breaks, but if you'll figure out a way to put it in an array, it's ok too. I really don't know how to do it, and I tried to google but didn't understand.. By the way, I don't want to change the txt file to js file, I need it to remain txt.. Can anybody help me with that? Thanks Alot, Ran |
