JavaScript - Div Tag- Save Edited Value
Hello,
Is it possible to store the edited value in the div tag in the original file, such that next time i open the HTML file the new edited value appears. Thanks in advance. Have a Good day. Similar TutorialsHello All, I found this awesome upload script and it works perfectly for what I need so far. The one problem is I can't get it to work for multiple (individual files). The script works like a user will click the browse button, select the file, and it auto submits uploading the file. Now the script is setup to handle multiple files selected all at once, but I need separate buttons for each file. So here is the main page Code: <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>HTML5 File API</title>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div id="main">
<h1>Upload Your Images</h1>
<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="images" id="images"/>
<input type="file" name="images" id="images"/>
<input type="file" name="images" id="images"/>
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script src="upload.js"></script>
</body>
</html>
Here is the upload.php file Code: <?php
foreach ($_FILES["images"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "uploads/" . $_FILES['images']['name'][$key]);
}
}
echo $_FILES['images']['name'][$key];
?>
And the upload.js file Code: (function () {
var input = document.getElementById("images"),
formdata = false;
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
if (formdata) {
$.ajax({
url: "upload.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;
}
});
}
}, false);
}());
I'm good with php, but don't know much with javascript and jquery so I don't really know how this works. Is there a way to adjust this so the multiple file inputs will upload. Right now it will only upload the first one. Here is it working. http://www.skafreaks.com/new2/upload/ Thanks for any help SkaFreaks Hey, I'm trying to make a game, I learned how to do so by reading tutorials but the problem is that I do not know how to implement the save/load function into the game, the tutorial surrounding that area was very unclear to me, and here I am... Any tips on how to make this work is greatly appreciated, I wouldn't asked if I hadn't tried my best and every way I could think of. I'm still quite new to coding so... The first piece of code is the game, the second one is what I'm trying to make the game work with. I tried for a while and got the game to reset back to values, but only the values I set in the code so it never actually worked. The tutorial doesn't give any live examples and I really am... not that bright when it comes to coding Sorry and thanks, all inputs are appreciated.

I have an image switcher script setup. Its very basic and changes the image displayed on click of a link. Here is what I currently have: Javascript: Code: <script type="text/javascript">
function changeIt(imageName,objName)
{
var obj = document.getElementById(objName);
var imgTag = "<img src='"+imageName+"' border='0' />";
obj.innerHTML = imgTag;
return;
}

Its very basic but does what I want. What I'm attempting to do is store the image selected as a cookie so that when users refresh/navigate to other pages the image stays to the one they selected. Is anyone able to help me out with this? Any help is greatly appreciated. Thanks, Chris Hi all, I found this script online that lets users on an iPhone drag boxes around the screen. The problem is that when you reload the page, the boxes are in different positions than what they were before the reload. Like, you would drag the boxes around and then reload the page, but the boxes would be in the default locations. I want the boxes to stay in the same spot that they were the previous time they moved them. Does that make sense? Anyways, here's the example I found online: http://www.manifestinteractive.com/iphone/touch/ Only works on iPad/iPhone/iPod Touch. It uses jQuery too so if you know of any way to do this, that would be excellent. Thanks. Hey Guys, I'm working on a Gameserver for a Game, written in JavaScript. I want to save all console.log()'s with Timestamp into a txt-file but I don't know how :/ Could you help me with it and tell me how I can do this? for example, I want to save User-Logins into the logs. This is the code I'm using right now. Code: case "LOGIN":
var data = PacketModels.login.parse(datapacket);
User.login(data.username, data.password, data.is_banned, data.is_online, function(result, user){
if(result){
if(user.is_banned == 1){
console.log("[WARNING] ".red + data.username + " tried to login. It failed because the User is banned!");
c.socket.write(packet.build(["LOGIN", "ISBANNED"]));
}else if(user.is_banned == 0){
if(user.is_online == 1){
console.log("[WARNING] ".red + data.username + " tried to login. It failed because the User is already online!");
c.socket.write(packet.build(["LOGIN", "ALREADYLOGGEDIN"]));
}else if(user.is_online == 0){
c.user = user;
c.enterroom(c.user.current_room);
c.user.is_online = 1;
c.user.save();
c.socket.write(packet.build(["LOGIN", "TRUE", c.user.current_room, c.user.pos_x, c.user.pos_y, c.user.username]));
console.log("[INFO] ".blue + data.username + " has logged in on Map:[" + (c.user.current_room_name).blue + "] X:[" + String(c.user.pos_x).blue + "] Y:[" + String(c.user.pos_y).blue + "]");
}

You need to do this with a server side language like PHP and if your going to all of that trouble you might want to study a database at the same time or soon after. Hi.. I have checkbox and I need to get his value. I create function for checkbox if checkbox is clicked it is true then the checkbox value is H else W. Code: function chk(){
if(document.getElementById('H').checked==true){
var H = document.getElementById('H'). value = H;
}
else if(document.getElementById('H').checked==false){
var H = document.getElementById('H'). value = W;
}
}
and I have function for save : Code: function ApproveLeaveOP(){
var H = document.getElementById('H').value;
document.sampleform.action="AddLeave.php?H="+H;
document.sampleform.submit();
}
<input type="checkbox" name="H" id="H" value="" onclick="chk()">
I don't know how can I add value to the checkbox if I click the value will be H if not the value is W. I am new in using checkbox. Thank you so much.. Hello all, i am a newbie here. I am starting to programme with javascript. I am designing a website. in This website there is an input with type = text and beside this input, there is another input with type = submit. If i open this website: The default value on the search text is "Enter a text", and if I click submit button, this button can recognize the value of the search text which is "Enter a text". <input id="searchText" type="submit" value="Enter a text"/> <input id="searchSubmit" type="submit" value="Submit"/> And then i modified a little bit. I have this javascript: var searchInput = $('#searchText'); searchInput.focus( function() { searchInput.attr('value', ''); }); The goal is, when I click on the search text, the default text is gone. And it worked. But if i write a new text on the search text, the submit button still recognized the value of search text as empty string. Can anyone please help me?? Thank you I am trying to do this and have some code im working with. I can load the file through a browse button then save it using the existing code. However, I want instead of the browse option to just preload the file into the textarea and then be able to save it. Code: <script language="javascript">
<!--//
var oFileSystem;
oFileSystem = new ActiveXObject("Scripting.FileSystemObject");
function ShowFile(sFilePath){
frmEditHTML.tarHTMLText.value = oFileSystem.OpenTextFile(sFilePath).ReadAll();
}

var oFile;
oFile = oFileSystem.CreateTextFile(frmEditHTML.filPath.value,1);
oFile.WriteLine(frmEditHTML.tarHTMLText.value);
oFile.Close();
}

Hi , i have got this img src html.. how do i write a javascript to auto save this image in C:\ without right click on the image? <img src="/user_images/V/VI/VIR/Virgo001/1135356474_ylittlekid.jpg" alt="1135356474_ylittlekid.jpg"></img> thanks for help! I have a long survey form and once its submitted it gets recorded into a database. I would love to be able to save a PDF version of the HTML form with all their radio buttons and textfields filled out at the same time its submitted. It would need a unique name that matches their record in the database (maybe it pulls the data that was entered into one of the form fields for the name). Whether it gets uploaded to an ftp or just emailed to a mailbox doesn't really matter. The purpose of this is to basically have a visual interpretation of the data by a single user. Is something like this even possible? This is code use to save XML file using Javascipt but it can't not save full Processing Instruction, example we have PI is <?xml version="1.0" encoding="utf8"> when run the code then PI is saved with <?xml version="1.0"> and sometime it doesn't word. Please help me fix, thanks PHP Code: function SaveXML(xmlDoc,filename) { var outputXML = xmlDoc.xml; var mfObj = new ActiveXObject("Scripting.FileSystemObject"); var absPath = getPath(); var file = mfObj.CreateTextFile(absPath + filename, true); file.Write(outputXML); file.Close(); } function getPath() { var path = document.location; var str = new String(path); var end = str.lastIndexOf("/"); var absolutePath = str.substring(8, end) + "/"; absolutePath = absolutePath.replace(/%20/g, " "); return absolutePath; } Hello. I am new to the forums (I just started my Javascript journey last week), and was hoping to get help with something. I am currently developing a page which allows access to music on a server. This music is being streamed, but users are also able to download this music (assuming they have the license to do so). All of the music uploaded is of the .mp3 format, however they have no filetype extensions, and were not named using any particular naming convention. Because of this, I was hoping to change the filename (when a downloaded is initiated) to variables I have stored based on the current song. I am currently simply opening a new page, in Chrome is looks like this: Code: chrome.tabs.create({ "url": song.url })
Hit presents the user with a prompt to save the file, however, its default name is a random alphanumeric string with no extension, as per their file name on my server. Is there an easy way to do this without renaming all the music server side? I do have the variables song.title and song.artist setup! All help is appreciated! Edit: Since this page is only for Chrome users, I listed the code I am using. I understand window.open and was originally using this. It functions the same, and if I need to revert back to using is instead, I shall. I'm trying to find the best approach for saving the checked value of a checkbox in SQL With this script the FieldName "Active" toggles yes/no onClick... That we can post to the database no problem... What I am having trouble with is saving the checked value. I want to make the FieldName Active =hidden, and only display the checkbox with correct value checked yes/no. Code: <script type="text/javascript">
var YesOrNo = (function() {
if(document.select.checkbox.checked) {
document.select.Active.value = 'yes';
} else {
document.select.Active.value = 'no';
}
});
</script>
<form name="select">
<input type="hidden" name="Active" size="10" />
<input type="checkbox" name="checkbox" onclick="YesOrNo();" value="on" />
</form>
I am doing a website project and I am currently designing product page. I have created the text boxes dynamically(as many boxes as the user wants) and he can drag and drop the text boxes in the page. I need to create a dynamic line from one text boxes to other text boxes and delete the test boxes which the user does not want. I have created the dynamic graphic line. I know the values of the text boxes can be saved using php in the backend. But is there any way the values with the dynamically created boxes(with <div></div> elements, not with the text boxes) with values and graphics line can be saved online and the user when log-in again can retrieve the work that he saved? Can we code this either in javascript/php? hi i in my project use of CKeditor i need Access to event save it namely i want user on click on button save i do a action please help me how to it do thanks Hi all, I have been checking out this web audio api app Beat Petite The thing that really interests me about it is that as the user alters the interface settings the URL changes, and all the settings can be recalled just by saving the URL (so if you make a cool drum beat you can share it with your friends by giving them the URL). I would love to be able to implement this feature on my own site but I have no idea where to start! Can anyone shed any light on how this can be done? I am not even sure if this is JavaScript that is controlling this or some other technology. Any ideas would be much appreciated. Thanks, Hulk Afternoon guys, wonder if I can get some assistance with some JavaScript I need, unfortunately my worst language. I have a large form that needs to prompt the user to save before leaving the page, if they have edited any of the fields inside it. Here is what I have thus far, and would like to keep it in the same format if possible: Code: function do_unload(){
if() {
confirm('Changes have been made to this page. Do you wish to save them?');
document.forms.frmlog.pAction.value='SAVE';
document.forms.frmlog.submit();
}
}
Code: <body onUnload="do_unload()"> </body> Basically, I just want to determine what inputs and selects have been changed since the page loaded, and have the logic for this in the IF statement, if that makes sense. Thanks in advance. Hi, In Google Chrome the 'chrome.tabs.captureVisibleTab(integer windowId, function callback)' method will return a data URL of the JPEG encoding of the visible area of the captured tab. We want to save that content as image to hard disk without opening/passing the contents into new html page. Does anybody know how it can be done by javascript. Please provide help. Thanks. Hello, i m new Javascript but knows basics of functions etc. ive created a website, which also has field to Submit Email addresses for newsletters.. Now, i have a TextBox (for users to write email addresses) and a Submit button in which i want to call a Javascipt script function which OnClick takes the value(email address) from the textbox and saves it to a .txt file on server. i think i am just missing a single line, the function name which will store the value.. i searched ovr the net but didnt find it.. plz help mee. Thankyou! |
