JavaScript - Unable To Read File Content
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?! Similar TutorialsI am trying to get a div's content to change using javascript but for some reason it is not working and i get no errors looking at the error console. the code that is waiting for the content... Code: <div style="font-weight: bold;">count = <div id="desc" style="float: left;"></div> descriptions to do.</div><br clear="all" /> the code that should change the content.... Code: <? echo("<script type=\"text/javascript\">
document.getElementById('desc').value='" . $count . "';
</script>");
?>
when i view the source code the javascript lines show like so... Code: <script type="text/javascript">
document.getElementById('desc').value='373';
</script>
do i have the javascript correct ? when someone selects a date it shows ok in the field but the checker script can not view it for some reason, i have an alert show the content, if i place the alert before everything it unblurs and the tick shows, but i have to click the alert off for the tick to show. The alert show nothing on the first run. just a thought, but would the DOM not be updating quick enough for the next line to read the content ? reason i ask is that with the alert line in the code it shows the previous state of the field when i change the date to something else.

attached is the datetimepicker.js you will need to remove the last part .txt from the above file name This is my first time posting, so please let me know if I am doing things as expected. When users click on a "Was this helpful?" link, an e-mail message displays with the page title (accomplished using a JS function). I want to put this is an external file so that it only needs to be updated once. Here's the code in the feedback.js file: Code: function feedback()
{
mail_str = "mailto:feedback@company?subject=Page Title: " + document.title;
mail_str += "&body=Thank you for your input.";
location.href = mail_str;
}
And here's the code in the page: Code: <script src="feedback.js" type="text/javascript"></script> ... Was this topic <a href="javascript:feedback()">helpful?</a> When I do this, an "object expected" error displays. When I put the code inside of the header, it works fine. What gives? 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 I 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 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. 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 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? 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. 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 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. 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">

Many thanks Backit Hello: I have a bit of an interesting delima: I have a form with select box which is dynamically db populated and based on the first selection, additional data populates two other linked boxes (a input and a textarea).

Mossa Hi all, I want to write i frame content to PDF file.Can any one help me how to do it Good morning to all and thank you for sharing so much information to the non coding public. While browsing the javascriptkit.com site I came across a wonderful script to help me with pagination on a web page. The directions are simple to understand but one part has me lost. The files contentfader.js and jquery-1.2.2.pack.js are to be downloaded but where do I put them? Here is the page with the script: http://www.javascriptkit.com/script/...ntviewer.shtml I know everyone is busy and my question is basic but I have to start somewhere. Thanks, Hi everyone so ive been doing some searching on how to save textarea content as a file and found ... Code: http://www.codingforums.com/showthread.php?t=32077 Saving works ok but the issue I have is that when you enter some text and hit the submit button the content of the page becomes the content within the the file your saving check demo so you can see for yourself: Code: http://6d8.info/demo.html So what I need is for the page to stay the same ie always demo.html with textarea and submit button and not the saving file content Any help is appretiated and as normal thank you in advance ...

Hi guys, My brain is not working. May be I need a coffee break. I need your expertise. Below is the code holding the textarea. Look for the element with the id : themessage Code: <table width="100%" border="0"> <tr><td rowspan="4"><input type="button" name="send_email" id="send_email" style="height:50px; width:100px;" value="SEND" onClick="return err_check();" /></td><td><span class="que">From : </span></td><td colspan="3"><?php echo $from_email; ?><input type="hidden" name="from_mail" id="from_mail" value="<?php echo $from_email;?>"/><input type="hidden" name="camp_id" id="camp_id" value="<?php echo $camp_id;?>"/></td></tr> <tr><td><span class="que">To : </span></td><td colspan="3"><input name="to_email" id="to_email" style="width:250px;" /></td></tr> <tr><td><span class="que">CC : </span></td><td colspan="3"><input name="cc_email" id="cc_email" style="width:250px;"/></td></tr> <tr><td><span class="que">Subject : </span></td><td colspan="3"><input style="width:300px;" name="subject" id="subject" /></td></tr> <tr><td rowspan="1" colspan="2"> </td><td><input type="checkbox" name="ori_pdf" id="ori_pdf" /> PDF Quotation</td><td> </td><td> </td></tr><tr><td colspan="2"><span class="que">Credit Application</span></td><td><input type="checkbox" name="corporate" id="corporate"/>Corporate</td><td><input type="checkbox" name="individual" id="individual" />Individual</td><td><input type="checkbox" name="cash" id="cash" />Cash Account</td> </tr> <tr> <td colspan="2" rowspan="3"></td><td><input type="checkbox" name="tabloid" id="tabloid" />Tabloid Example</td> <td><input type="checkbox" name="broadsheet" id="broadsheet" />Broadsheet Example</td></tr> <tr><td><input type="checkbox" name="colmt" id="colmt" />Column Sizes Tabloid</td> <td><input type="checkbox" name="colmb" id="colmb" />Column Sizes Broadsheet</td></tr> <tr><td><input type="checkbox" name="maps" id="maps" />Maps / Distribution</td><td colspan="2" align="right">External Attachments <input id="upload_file" name="upload_file" type="file"/> </td></tr> <tr><td colspan="2"><span class="que">Message :</span></td><td colspan="3"> <textarea id="themessage" name="themessage" rows="15" cols="80" style="width: 100%"> </textarea> </td></tr> </table> Now on a button click, I'm trying to pass some values which one of them happens to be what ever that is entered in the textarea. For some reason, the stupid JS is not reading. But I think it is me that is stupid, not JS. Below is the code i'm running to get the value. Code: var message = document.getElementById('themessage').value;
alert(message);
The alert simply returns blank. There is an alert, but no value even where there is text in the text area. Can someone please shed some light on this. pretty please Hi all! I created a form where users are allowed to delete a specific row of data by clicking the "cancel" button from the drop down menu. However, I have a problem deleting my data using the javascript. Apparently, I only able to delete the first row of the data but not for the rest! The following is the code i have: PHP Code: <html> <body style="background-color:#E0FFFF;"> <script language="javascript" > <!-- hide function submitRequest(val) { document.forms[0].submit(); } // end hide --> </script> <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_course", $con); $result = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); $result1 = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); echo "<table border='1' cellpadding='2' cellspacing='0'> <tr> <th>CourseCode</th> <th>CourseName</th> <th>Year</th> <th>Sem</th> <th>Grade</th> <th>Option</th> </tr>"; ?> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['CourseCode'] . "</td>"; echo "<td>" . $row['CourseName'] . "</td>"; echo "<td>" . $row['Year'] . "</td>"; echo "<td>" . $row['Sem'] . "</td>"; echo "<td>" . $row['Grade'] . "</td>"; echo "<td>"; ?> <?php ?> <form name="form1" action="submitDelete.php" method="post"> <select name="cancel" onchange="submitRequest(this.value);"> <option value=> </option> <option value="<?php echo $row['CourseName'];?>">Cancel</option> </select> </form> <?php echo "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> <br/> <br/> </body> </html> Thanks in advance! |
