JavaScript - How To Get Document.ready Using Javascript
In Jquery, there are following two concepts
1. Document.ready 2. Window.onload How can i get to know when document is ready to use using pure javascript? Similar TutorialsHi there. I want to slide in (jquery) a link in the bottom right when the page loads that offers the user to be pushed back to the top of the page. So far all is well. I have it appearing at width 1024 or bigger. With a media query set in order for it not to appear for smaller devices: #totop { position: fixed; bottom: 0; right: 10px; background: #FFF; color: #000; padding: 10px; -moz-border-radius: 5px 5px 0 0; border-radius: 5px 5px 0 0; display:block; -moz-box-shadow: 10px 10px 5px #000; -webkit-box-shadow: 10px 10px 5px #000; box-shadow: 10px 10px 5px #000; } @media screen and (max-width: 1023px) { #totop { display: none; /* Remove to top button */ } Now I understand I want an if statement checking whether the css is to display block or none. Or if this doesn't work have an if statement checking the screen width itself rather than media queries. So far I have this: $(document).ready(function() { if( $('#totop').is(':visible') ) { ("#totop").slideDown("slow"); } else { ("#totop").hide(); } }); Please help! All, I currently have this code to make a post to my database: Code: var $dataString = 'name='+ $name + '&black_white=' + $black_white + '&color=' + $color + '&color=' + $other + '&other_text=' + $text;
$.post("save_edits.php", {image_save_string: $dataString}, function(result) {
$("#multiple_images").hide();
$("#result_success").html("<font color='red'>We've successfully saved your photo edits!</font><br><br>");
$("#image_divs").html(result);
});
Within the result I'm actually recreating the form for them to use if they want. I have a decent amount of jQuery that got initialized when the original page was loaded. Once I get my new form it doesn't work because it wasn't originally included in the page initialization. Is there a way just to call the document.ready function again to have it reinitialize my form elements again? Thanks in advance. Hello all. I have fairly simple questions regarding modifying this script: http://papermashup.com/create-a-dynamic-form-preview/ to dynamically show different parts of a form on another part of the page. I am looking to use it on most parts of my form and would like a little clarification. First is the use of $(document).ready(function() or $(function(). It works using either, my question is which is preferred? As I understand it using $(document).ready(function() starts the DOM immediately on page load and is useful if you need something right away. I am also using this script: http://www.dynamicdrive.com/dynamici...formwizard.htm for the form. Since the preview script is being used with the form to wizard, I don't really need it until the rest of the form loads. Another question would be, is there a cleaner way to go about using the preview script on say 10 different form inputs independently? For example in a single function rather than 10 different function/updates? I have an example of what I am trying he http://jsfiddle.net/anhyG/1/ Thank you in advance for any help! I have am currently taking over as the developer for this web site, and the developer who left the project unfinished wrote a script. What it does is takes posts from vBulletin forums, for instance News posts, and then it grabs the posts by ID and Title and writes the title on the home page of the web site. The problem right now that I have is the test wraps, you can see what I mean here http://www.netcodeilluminati.com/v2 If you look on the left, I want to make the text cut off after a certain amount of characters with "..." at the end as if there is more to the title but you can't see it. Here is the script: for (x = 0; x < 5; x++) { document.write("<li><div class=\"li_icon\"><img src=\"images/icons/text.png\" alt=\"text\" /></div><div class=\"li_text\">"); document.write("<a href=\"../forums/showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a></div></li>"); } I was wondering how I could go about doing this. Thanks for any future help. -Kevin In my program there is table which is retrieved and then there radio buttons, after selecting any radio button other columns get exapanded into textboxes to edit info. Now for expansion I have used div<id = > tag for each textbox and In javascript I have a function for showing textbox after clicking a radio button.In that I have used , arr.length=Length of the rows in table function edit1(el) { for(var i=0;i<arr.length;i++) { if(el.value==arr[i].value) { //document.getElementById("test[" + i + "]").value Not workking //document.getElementById('dname['+ i + ']').style.display = block"; Not working document.getElementById('dname').style.display = "block"; document.getElementById('dmarks').style.display = "block"; break; } else { document.getElementById('dname').style.display = "none"; document.getElementById('dmarks').style.display = "none"; } }//end for }//end if } In HTML, while($row1=mysql_fetch_array($rs1)) { echo "<tr>"; /*<td>44:<div id=d4 style="display:none;"><input type=text name=t4 id=idtext></div></td></tr><br>*/ ?> <td><input type="radio" name="select" value="<?php echo $row1['rollNo'];?>" onClick='updateRec(this);'><?php echo $row1['rollNo']; ?> <input type="radio" name="select" value="<?php echo $row1['rollNo'];?>" onClick='hiding(this);'>hide</td> <td><?php echo $row1['name']; ?><div id="dname[]" style="display:none;"><input type=text name="tname[]"></div></td> <td><?php echo $row1['marks']; ?><div id="dmarks[]" style="display:none;"><input type=text name="tmarks[]"></div></td> </tr><br> <?php } // end while ?> </table><br><br> Here I have to take array of div id's = "dname[]" but don't know the syntax for document.getElementById('dname').style.display = "block"; in which dname is array Plz help. I'm currently working on an HTML executor and would like users to be able to put javascript in their code if they wish to do so. Currently I have their input sent to an iframe via document.body.innerHTML. The problem, though, is that user submitted javascript doesn't work (with the exception of anything placed in the onload attribute of an image). Any suggestions?
Without elaboration plz see my code: Code: <body>
<script>
var b="s";
</script>
<button target="_blank" onclick="window.open('http://......php?b="javascript:document.write(b);"&id=2&q=<?php print $_GET['q']; ?>','1','');return false;">xyz</button>
</body>
i don understand why this javascript:document.write(b); doesnt work in url... i know its simple yet it make my hair out of my head. plz count it.. New to this. This code works in IE but does not work in firefox. It just stays on the same page and does nothing. Please Help! Code: <table>
<CFFORM action="mypage.cfm METHOD="post" name="Login" rel="nofollow" target="_blank" id="go">
<cfinput type="hidden" name="decrypted" value="#decrypted#">
<tr>
<td>
<a class="K" HREF="javascript:document.go.submit();">My Page</a>

I've written the following html, <html> <head> <script type="text/javascript"> function createpage(){ var first = document.getElementById('first').value var second = document.getElementById('second').value var third = document.getElementById('third').value var j = window.open('random'); var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>'; j.document.write(new_page); j.document.close(); } </script> </head> <body> <form action=""> <p> First Link: <input type="text" id="first" name="first"/> Second Link: <input type="text" id="second" name="second"/> Third Link: <input type="text" id="third" name="third"/> <input type=BUTTON value="Submit" name="mySubmit" onClick="createpage();return false;"> </p> </form> </body> </html> With the intention to eventually implement it into a website that "mashes" several URLs together into a tinyurl that, upon being opened, creates several tabs of the content the creator wanted in the single URL. Does that make sense? In order to best do this I figured a page with a random character string (I haven't yet implemented this part, for now 'random' holds the place of the new page/link) would have to be created that would launch all the tabs and then close itself. Here's what it should do... 1) User enter 3 URLs into three forms: First Link: <input type="text" id="first" name="first"/> Second Link: <input type="text" id="second" name="second"/> Third Link: <input type="text" id="third" name="third"/> 2) User clicks Submit button that calls "createpage()" function that's declared in the <head>er. The first part of this function declares the links that were inputted as variables first, second, and, third. <script type="text/javascript"> function createpage(){ var first = document.getElementById('first').value var second = document.getElementById('second').value var third = document.getElementById('third').value 3) "createpage()" function then declares a new window named 'random' to variable j (I have random.html stored in the same folder as this project. It is empty.) var j = window.open('random') 4) Next "createpage()" creates a variable that stores a full page's html code that includes a script that launches each link individually with window.open(). var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>'; 5) "createpage()" writes the code (stored in variable 'new_page') to document 'random' with j.document.write(new_page); 6) "createpage()" closes the document. Hello, I would like to know how to make a website (in this case, a parent div) viewable only if JavaScript is enabled? I tried to develop a code that can do this, but could not find the solution. Code: <html>
<head>
<script type="text/javascript">
window.onload=function()
var="true"
if(JavaScript.enabled)
{
document.getElementById('true')
}
OnClick()
{document.getElementById('toggle').onclick=function()
{document.getElementById('jahava').style.display=(document.getElementById('jahava').style.display!='none')?'none':'';}}
</script>
</head>
<body>
<noscript>You must have JavaScript enabled to view the website.</noscript>
<div id="jahava">Contents Here</div>
</body>
</html>
I'm trying to diagnose the javascript part of an ajax script: Code: <form>
<ul id='May120128AM' name='apt_time' value='May120128AM'>
<input type="hidden" id='May120128AMhidden' name="user_id" value='May120128AM'>
</form>
<script type="text/javascript">
<!--
var request;
request = new XMLHttpRequest();
function checkData()
{
alert(request.readyState);
}
var apt_time = encodeURIComponent(document.getElementById(May120128AM').value);
var userid = encodeURIComponent(document.getElementById(May120128AMhidden').value);
var parameters = "apt_time"+apt_time //+"&"+"user_id"+userid;
request.open("POST", "/cgi-bin/my_script.php", true);
request.onreadystatechange = checkData;
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.send(parameters);
//-->
</script>
The checkData script puts each readyState in an alert box, so I know the javascript is firing. If I change the red line of code to this, the alert boxes no longer pop up, so I assume the javascript is not firing: Code: var parameters = "apt_time"+apt_time+"&"+"user_id"+userid; I thought name/value pairs were written like this: Code: name1=value1&name2=value2 I though that was exactly what the red line of code was doing. Does anyone know why it isn't firing? UPDATE: This works: Code: var parameters = "apt_time=+apt_time+&user_id=+userid"; I don't know why the above works and the other doesn't. They both look like they do the same thing - this: Code: apt_time=value1&user_id=value2 Hi Guys, I've written the below code which submits to a servlet, does a bit of processing and returns a JSON object. I'm reaching the servlet, but I never reach the alert("ready()") in the JavaScript. It looks as though the readyState never actually reaches state 4. Any ideas what is wrong ?? Thanks Code: function fetchhits() {
var httpRequest = null;
var url = "http://localhost:8080/Json/FetchTopHit?amount=1";
try {
httpRequest = new XMLHttpRequest(); /* e.g. Firefox */
} catch(e) {
try {
httpRequest = new ActiveXObject("Msxml2.XMLHTTP"); /* some versions IE */
} catch (e) {
try {
httpRequest = new ActiveXObject("Microsoft.XMLHTTP"); /* some versions IE */
} catch (E) {
httpRequest = false;
}
}
}
httpRequest.open("GET", url, true);
httpRequest.onreadystatechange = handler;
httpRequest.send(null);
}
function handler() {
alert("hander() start");
if (httpRequest.readyState == 4) {
alert("ready...");
if (httpRequest.status == 200) {
processJson (httpRequest.responseText);
}
}
}
function processJson(jsonObjectString) {
alert ("Process the Json Object");
}
Hi, I used this link fader script on my website: http://www.javascriptkit.com/script/...inkfader.shtml. The browser activates this script when I move my mouse over the link - that's understood. But unlikely the browser needs 1 or 2 seconds to activated it (to read it) so the whole effect is delayed - it happens every first time I use the links after loading the page. Question: is there a way to make the browser "read and remember" the script before I use the link so no delays appear? Any onLoad formula? Thanks I have a website which includes stories with multiple chapters. These chapters have a set of clickable arrows at top and bottom to take you forwards and back through the chapters, including a "last chapter" arrow. When a story is in progress, the URL of the last chapter changes with each chapter added. Rather than having to go back into every previous chapter and change the URL of the last chapter by hand, I set them up so that the "last chapter" arrow is actually in an inline frame. That way, I only have to change the URL once, in the file go_end.htm which is the source for the frame. So both the picture of the arrow and its hyperlink are being accessed from outside. My web pages are also set up to run on all major browsers and to detect the window width and resize all the artwork to fit, regardless of the browser and whether or not it accepts percentage sizes. Go_end.htm is no exception - it contains Javascript code which resizes the arrow so it is the same size as the ones which are actually in the parent page, outside the frame. This setup works perfectly in IE and Netscape, but Google Chrome either fails to display the arrow or makes it huge so it doesn't fit the frame. This seems to be because their superfast new Javascript editor is *too* fast. If I bung an alert command into go_end.htm, asking it to say the value of picWidth (the variable which sets the width of the arrow) as it loadfs, what happens is this. Google Chrome displays an alert saying that picWidth is zero, then loads the first instance of the inline frame with no got-to-end arrow. Then it displays an alert giving a proper value for picWidth and loads the second inline frame with the arrow correctly displayed and sized. If I take out the alerts, it doesn't load the arrow in *either* frame. It's obvious that inserting the alert command somehow forces it to recognise the value of the variable which it then retains for long enough to load the arrow on the second pass. Any ideas for some command other than alert which would trick it into not loading the image until it's recognised the variable? If I put a time delay on loading the frame I can't see that that would help - the problem is that from the point at which it starts actually loading the frame it needs to wait for the variable to be set. My code is here and it works ... However, I would like my dynamic table to show on the same page as my body and not on a new blank page. I have created a DIV and try playing around with the document.getElementById('monTab').innerHTML but it's not working out for me ... What am i missing ?

I found this line in one of the scripts on javascript.kit <code> if(document.layers|| document.getElementById|| document.all) </code> Could someone give me an idea on why this line would be used in a code? Thank you very much I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed. So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write. Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script. Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script. Any suggestions, I'd greatly appreciate it. Or even if you've encountered a similar problem, and know that it just isn't possible in IE or Opera, that would be fine too. Thanks in advance! Hello everyone. I'm having a little problem with creating a element in internet explorer. The element that I'm creating is a div with a few style attributes to to it. The div is suppose to cover the whole page almost like a black transparent window on the page. However it is not. The messed up part about this is that it works fine in Firefox, google chrome and I'm sure other browsers (though haven't tested) and when I go to apply the div in my actual code as javascript is suppose to when you tell it create it, it works fine. No problems whatsoever... I'm not to sure what I'm doing wrong here and it would be great if I could get some help with this. Thanks Code: function showPhotoUpload() {
var overlay = document.createElement("div");
overlay.setAttribute("style","z-index:3; background:#111111; width:100%; height:100%; position:absolute; top:0; opacity:0.5; filter:alpha(opacity:50);");
document.body.appendChild(overlay).lastChild;
}
