JavaScript - Read Text File
hi, i have looked all over the internet but i can't find anything that works.
All i want to do is simply read from a text file. Thanks Similar TutorialsI use a PHP page to set elements of a text file on our web server and I want to create a javascript function to intermitently check the contents of that file and if an element in that file matches a criteria I want to act on it... So, I do this <script type="text/javascript"> t = setInterval("CHECKFILE()",5000); </script> This calls the CHECKFILE function every 5000ms <script type="text/javascript"> function CHECKFILE(){ } </script> How, in the CHECKFILE function can I read from a file called FILE.txt for example?? In PHP I can use $myFile = "FILE.txt"; $theData = file($myFile); And this gives me an array, with each element containing one line from the file Can I do similar in Javascript? Or can I add PHP into the JS to do it for me? Thanks Ok, I am currently working on an announcements portlet for a dashboard that my team is creating. What is desired is to be able to have this portlet access a stored text file (file can be edited so content is subject to change) that will have all the information needed for these announcements. The JavaScript will then write it into a html file. I am a novice at html, and javascript; and i was hoping that if anyone had any advice, ideas, or a helpful link that could point me in the right direction I would much appreciate it. hi i m creating a webpage using javascript and php where i need to upload a doc file or zip and read all the words in doc file if it is zip i need to read all the words in all the doc files. i m trying to upload using file input but it does not show path of file only file name how i m suppose to upload and read it. I am wanting to setup a dependant drop down where when a user clicks on the first drop down, it changes the contents of the second. The way I intend to do this is via a csv file. I have found several scripts but I have been unable to get them to work. Two of which a http://answers.yahoo.com/question/in...3114347AA7GYJ7 http://purbayubudi.wordpress.com/200...ng-javascript/ The first is the better option from what I can see. but the problem is readyState seems to be always 1. I am wondering if someone could perhaps give me a few moments to see if I can get this to work or suggest a better solution. I don't want to use a database approach, at least not yet. for some reason I am unable to read the file contents, or it could be something else, I added in some extra code to see where the script got to and I only get to see '1' on the output. Is there something else I have missed ? I am wanting to ready each line one by one and replace a phrase with another, then output the new line. I visit the 1.txt file in my browser and the file shows fine. var txtFile = new XMLHttpRequest(); txtFile.open("GET", "http://mysite.com/convertJS/1.txt", true); txtFile.onreadystatechange = function() { document.write("1<br>"); if (txtFile.readyState === 4) { // document is ready to parse. document.write("2<br>"); if (txtFile.status === 200) { // file is found document.write("3<br>"); allText = txtFile.responseText; lines = txtFile.responseText.split("\n"); document.write(lines + "<br>"); // I shall be altering the text in each line, search and replace, so only need to be able to read one line at a time. } } } txtFile.send(null); // close file. sorry that i used the quote method to post, but when i used [ code ] it corupted the text as the document . write lines?! Hi, i need to read a files contents to an array so that i can check which lines of the file i need to write back. im not very good with arrays and haven't had any luck so far. thanks Hi, i have a question, is JavaScript can read an external file? i have an ear file, can it read external file without the external file compile together in the ear file? can we do so? Hi guys, here again with another question. I would parse a file, my js read fine an html file, but this one is an export from msword. I don't know if this is the problem. I can't change the file. here is how my js read: Code: <body>
<input type='button' value='Load' onclick="doLoad()" />
<script type='text/javascript'>
/* THIS IS THE FILE TO READ */
var fileToRead="test.html";
/* THIS FUNCTION IS TO READ THE HTML FILE */
function IO(U) {//LA MOD String Version. A tiny ajax library. by, DanDavis
var X = !window.XMLHttpRequest ? new ActiveXObject('Microsoft.XMLHTTP') : new XMLHttpRequest();
X.open('GET', U, false );
X.setRequestHeader('Content-Type', 'text/html')
X.send('');
return X.responseXML;}
function doLoad(){
/* HERE IS THE CALL TO READ THE FILE */
var orari=(IO(fileToRead));
var arrTR=orari.getElementsByTagName('tr');
var arrTD_3nd_line=arrTR[1].getElementsByTagName('td');
var arr_p_1c_3l=arrTD_3nd_line[0].getElementsByTagName('p');
alert(arr_p_1c_3l[0].nodeValue);
}
</script>
and here is a snip of the html i read: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

.... and so on.... the problem is that my error console (from firefox) when i click my read button (not when i load the page) gives me errors: Code: sintax error: source: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> if i comment this it give me: Code: missing tag </meta>
source:
</head>
and if i put Code: </meta> another meta is required and so on. But i can't modify the source i read, so is there a way to read this file? Many thanks Backit I am having trouble with JavaScript code and do not know why it is not working. I have the code I think is right but it is not showing up in my browser when run. Any ideas? Also are there any other ways to read in an xml file using javascript? please list if so. dear all i have some read only text box which i want to get in write mode the code i am trying is.. function f2(txt1,txt2,txt3) { document.form1.txt1.readOnly=false; document.form1.txt2.readOnly=false; document.form1.txt3.readOnly=false; } <input type="text" value="<%=rset.getString(1)%>" readonly id="tex" class="tb2" name="u_name_0"></td> <td><input type="text" value="<%=rset.getString(2)%>" readonly class="tb2" name="u_pass_0"></td> <td><input type="text" value="<%=rset.getString(3)%>" readonly class="tb2" name="u_role_0"></td> <td><input type="submit" value="delete" name="submit_<%= i%>" class="tb3"></td> <td><input type="button" value="update" onClick="f2('u_name_0','u_pass_0','u_role_0')"></td> but its not working.. some body help me out.. I would like to ask is it posible to add text from a text file to a text area on a page.. Philp if you read this i am not asking for a javascript code i am asking wether or not it can be done. P.s if your a nice person like philp is not and you want to private message me if you have one I'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) 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. 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.
Is allowing a button a create a text file a security issue? If so, how do I collect the names of users who have clicked a certain button?
Dear frnd I wanna read on html page , and i have script : " [I]<html> <head> <script type="text/javascript" language="javascript"> function Read() { var Scr = new ActiveXObject("Scripting.FileSystemObject"); var CTF = Scr .OpenTextFile("C:\\123.txt", 1, true); data = CTF .ReadAll(); document.write("<pre>" + data + "</pre>"); CTF .Close(); } </script> </head> <body onLoad="Read()" > </body> </html> [I] " But as its using activex control not allowing in all browser . Have you any other way with pure js to read the file contains ? or allowing activex in all browser ? 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. I heard there is something called XMLHttpRequest that is compatible to all browsers. What does that actually do? Is there something to do with Javascript? Thank you.
