JavaScript - Write To Text File Using Xmlhttprequest?
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.

Hi, I have an idea for putting news articles on my phone to read later when I have time. I'd like to be able to right-click the text of an article and choose "Send to Phone Queue." When I've got a few articles in the queue, I'd like to be able to bluetooth the file to my phone. I know some HMTL and CSS, but I'm very much a novice when it comes to JavaScript. I'm thinking that I probably can't even do a lot of this with JS because of it's limitations (i.e. writing to a file). Will I need to use PHP or Java for writing/bluetoothing the file? I was playing around with extracting the body-text of an article from FoxNews.com. I didn't get very far but you can see where I'm going with it. I welcome any comments, criticisms, etc. Thanks for anything you say, even shooting this down as unrealistic. Code:
function getBodyText() {
var divList = document.getElementsByTagName('div');
for ( i=0; i<=divList.length; i++) {
if (divList[i].getAttribute("class") == "entry-content KonaBody") {
. . .
I am wondering how can I return the variable senttext from the function below? I have declared it and when I alert(senttext) below it appears as I want it but I need to return it and pass it to another function. When I change alert() to return the variable becomes undefined??? var senttext; function getData() { if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } req.open('GET',"http://www.site6.certcoordering1.com/Download/recall.txt" ); req.onreadystatechange = function() { if (req.readyState == 4) { if (req.status == 200) { senttext ='<table style="border:thin black solid"><tr><td><h2>Recent</h2></td><td><h2>Recalls</h2></td><td></td><td></td></tr>' ; var ad2 = req.responseText.split("\n"); for(i=0; i<ad2.length-1; i++) { // now split by comma var ad3 = ad2[i].split(","); senttext += '<tr><td><p>'+ad3[0]+'</p></td><td> <a href="http://www.site6.certcoordering1.com/Download/'+ad3[2]+' rel="nofollow" target="_blank">'+ad3[1] +'</a></td><td></td></tr>' } senttext += '</table>' ; alert(senttext); // I need to return senttext, not alert! When I send it it becomes undefined? } else { alert('File did not load correctly.'); } } } req.send(""); } I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page. The script works fine when the requested XML file is stored on the same server as the script. The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers? Thanks in advance for any help.

var xhr = false;

Hi, I was hoping you could help me, I was wanting to write text to the screen but without re-writing the whole screen (e.g. document.write();. I wish to take text and put it in a function, modify it, then display it. So far I have: Code: <script type = "text/javascript">
function calculate(text){
var x = "10.0";
var gpa = text.replace(/0.0/g,x);
document.getElementById("text").innerText=gpa;

<p id = text >Your Grade Point Average (GPA) is: 0.0</p>
<button type="button" onclick="calculate(text)">Calculate</button>
Your help would be really appreciated I would like to know how to do things. 1. I would like to know how i would code a javascript so if i edit the text inside of either a certain div or in the javascript document itself (which ever would work, would like to have it take the text from a div but not too picky) and then have it write that text in other parts of the same page and other pages by like putting a javascript code in it's place or however you would do it. Basically if i write "hello world" in the div/javascript document, it will write "hell world" in multiple places just from me editing that one part. ok so help with this would be awsome. My second thing. 2. I would like to take and use some javascript function, such as document.write or what ever to do pretty much the same thing as my first thing as my first problem, but with a div, for like a navigation bar or etc. So any help would be greatly appreciated! =) THANKS! Hello: I have two input boxes on a form which receive the first and last name of a user. I want to be able to use charAt() to get the first letter in each box and pass it to a third box on the same form. Is this doable? May I request some help? I was thinking something like the function below would be the starting point --I stand correct, as it is not working. Code: <script type=\"text/javascript\">
var str=\"Mossa\";
<!--document.write(str.charAt(0));-->
document.write('<INPUT TYPE=text size=2 VALUE=\"str.charAt(0);\">');
var str=\"Barandao\";
document.write('<INPUT TYPE=text VALUE=\"str.charAt(0)\">');
<!--document.write(str.charAt(0));-->
</script>
Any thoughts! Mossa Hello, I use a iplocator api, which is javascript and gives out the city name, country and zipcode output PHP Code: <script language="JavaScript" src="http://www.somesite.com/somefile.js?key=apikey"></script> <script language="JavaScript"> <!-- document.write(ip2location_isp() + ', ' + ip2location_city() + ', ' + ip2location_zip_code() + ', ' + ip2location_net_speed()); //--> </script> my question or where i need help is that, i would like to output each of those as a hidden text field, so later i can store into mysq database with POST method from the hidden field. thank you in advance for your time n help I'm starting to learn javascript and trying to get the below code to work with newer browsers. I'm not sure how to implement the below to make it work with XMLHttpRequest. There is a small form that uses this function to allow you to select an xml file to load. Your help is much appreciated. Thanks. Code: function importXML() {
if (document.implementation && document.implementation.createDocument) {
xmlDoc = document.implementation.createDocument("", "", null);
xmlDoc.onload = createQuiz;
}
else if (window.ActiveXObject) {
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.onreadystatechange = function () {
if (xmlDoc.readyState == 4) createQuiz()
};
}
else {
alert('Your browser cannot handle this script');
return;
}
xmlDoc.load(document.getElementById('file').value);
}
Ok, so I have built a website using galleryCMS, a pre-built CMS for images, which outputs XML via php to an address of: http://www.granitesupermarket.ca/login.php/view/xml Firefox and Chrome can pull the XML from the webpage using my code, however IE does nothing with it at all. I have found that if I use a page with a proper xml extension then the code works fine (ie test.xml); however, without the .xml it seems like IE does nothing?? I am not the most advanced user, so tampering with the CMS is not the best option for me... is there any workaround that I might be able to employ? Maybe a way I could take the xml I get from "login.php/view/xml" and save it to gallery.xml on the same server? Any help or ideas would be helpful. Code: <html>
<head>
<title></title>
<head>
<body>
<script type="text/javascript">
// Get XML function
function loadXMLDoc(dname)
{
if (window.XMLHttpRequest)
{
xhttp=new XMLHttpRequest();
}
else
{
xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",dname,false);
xhttp.send();
return xhttp.responseXML;
}
// XML source
xmlDoc=loadXMLDoc("login.php/view/xml")
t=xmlDoc.getElementsByTagName("thumbnail");
// TEST THAT XML IS WORKING
document.write(""+ t[0].childNodes[0].nodeValue + "");

I tried posting this same thread under AJAX and I didn't get a single response. I am wondering if it may be in the wrong section so I decided to try here. If this is bad posting etiquette, I apologize. Hello. I am trying to use a form to submit values to MySQL and then have a Google map returned that has certain parameters. I have modeled this code after an example I found on w3schools. I believe that this is strictly a javascript coding problem. This is the code that I am using: Code:

The code is designed to drop the map into the "maplist" div. In the code above, you see that I have the line "alert(xmlhttp.responseText);" which was originally: document.getElementById("txtHint").innerHTML=xmlhttp.responseText;" I wrote the php page so it would return code as shown below. This is the actual responseText received from the alert. Code: script type="text/javascript">
var map;
function initialize() {
var latlng = new google.maps.LatLng(34.65, -83.9);
var options = {
zoom: 9,
center: latlng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var infoWindow = new google.maps.InfoWindow;
var html;
var map = new google.maps.Map(document.getElementById('map_canvas'),
options);
var point = new google.maps.LatLng(
parseFloat(34.558350),
parseFloat(-84.250122));
var marker = new google.maps.Marker({
position : point,
map : map,
icon : 'http://labs.google.com/ridefinder/images/mm_20_red.png'
});

Hi there, Im looking for a general function which would work for most browsers when using the xmlhttprequest() I am just trying to send input data to the server store it and send back a response. I have one that works for both ie and ff, however when using ff the function does not return the text from the request to the server, but does with ie no problems. Any help would be much appreciated. Thanks Code: /* get response http request */
function getData(cURL) {
var xmlHttp = null;
xmlHttp = new XMLHttpRequest();
/* branch logic for ff or ie */
if (navigator.appName=='Netscape')
lSynch = true;
else
lSynch = false;
xmlHttp.open( "POST", cURL, lSynch );
xmlHttp.send( null );
var info = xmlHttp.responseText;
return info;
}
This question hovers between PHP and JavaScript, but I think it fits here a little better. I've got a web app that does a lot of asynchronous calls to various PHP pages. I'm familiar with using an iFrame or div to hold a controller, then making forms post to that controller so you can see the output. However, I'm not doing a lot of submitting forms. Typically, I utilize the onclick event of various elements to initiate an XmlHttpRequest that jumps over to a PHP page and back. I'm looking for a way to easily debug my PHP code. Right now I'm using Firebug (on Firefox) to look at the HTTP requests. I can see the post data and response and all that, which is good. However, it requires a good amount of clicking and time to get to that data. Is there an easier way to do this? Ideally I'd love to include some sort of debug window that displays all of the PHP controller errors and things that I echo out. Hi, because i need to get rid off Code: <iframe src="my.php"> in my html page, i have decided to replace it with javascript function which will get data from the server and will insert it into div section.But i dont know how can i obtain html page from my.php script... I know there is function XMLHttpRequest, but does it use current session from the browser ( my.php is protected - it does check the $_SESSION variable ) ? And does work this function in Mozilla ? hello all, I am trying to see if the w3schools example works on my site with a collapsible panel. here is what I have: Code: <script type="text/javascript">
function getXMLcontent() {
if (window.XMLHttpRequest)
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
document.getElementById('CollapsiblePanel1').style.visibility = 'visible';
document.getElementById("CollapsiblePanelContent").innerHTML=xmlhttp.responseText;
xmlhttp.open("GET","showfunction.php?fname=" + document.getElementById('functions').value, true);
xmlhttp.send();
alert("showfunction.php?fname=" + document.getElementById('functions').value);
}
</script>
the panel shows up as a thin grey line because no text is being thrown into it from the 'responsetext' property. I don't really know anything about what I'm doing. Just trying to copy and paste what the website example is. is there anything else I should know about what I'm doing, that would at least tell me why I'm not getting the data back out of the server like I should be? the 'functions' element on the page is a dropdown box, but it is not inside of a form tag. does that make a difference since I am using 'GET'?? thanks! |
