JavaScript - Can't Access Web Control From Javascript Function
This is a question more about an ASP.NET web application, but javascript is involved, so I'm hoping some javascript gurus can assist me.
I'm working with a web application that needs to get access to an ASP.NET web control (a button) in javascript. The problen is that since the control is run on the server, javascript can't access it in the standard way (i.e. document.getElementById(controlId); ). I've actually solved this problem before in a different application, but my solution there doesn't seem to work here for some reason. I have this in an aspx file: Code: <script...>
...
function myfun()
{
var b = document.getElementById("<%=SaveButton.ClientID%>");
alert(b);
}
</script>
...
<asp:Button ID="SaveButton" Text="save" OnClientClick="myfun()" ClientIDMode="Static" runat="server" UseSubmitBehavior="False" />
I have a designer class in which the button is declared (and therefore exists in the server-side codebehind): Code: protected global::System.Web.UI.WebControls.Button SaveButton; But when I click on my button, the alert box says "null". Why am I not able to get my button in the javascript function? Some things to note: *The button exists within a content tag: Code: <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> *I'm working within Visual Studios 2008. Similar TutorialsSup gents. Excuse my tenaciously novice questions, but dont disparage just yet, im beginning to grasp how the mechanism behind the code words, in due part to your helpful suggestions Im in the last stages of the code. In this section i have added three methods, whose function is to direct access control over the ciphers i will be adding shortly. I firstly need for the methods to be working. What they do is, categorize the set of values inside the first array and give a set of names privileges. The three methods that deal with the access control are link(), secondgroup() and third group. Ive assigned that the first three names( link() ) can access all the ciphers, ie administrators, the next three names ( secondgroup() ) can only access the shift, permutation and vigenere ciphers and the rest ( thirdgroup() ) can access the other remaining ciphers. But ive added so much code at once that i overwhelmed myself and i now i cant figure out where ive gone wrong, be it in the syntax or the logic Code: <html>

Hi, Is is possible to access a global variable for use inside a function? Thanks for help in advance Mike Code: <html>

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic. Now for the problem: When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page". I don't know if there is a better way to go about this, but as for this route, I am stuck. Any help is greatly appreciated! -Shane Hi Guys, I have a Javascript function that toggles a 'show/hide' table row: //CONTROL Code: <a href="#" onclick="toggle('ROW 1, this)"><img src="../../Images/plus.gif" border="0" /></a>
//JAVASCRIPT Code: function toggle(id, obj) {
var matchingElements = new Array();
if (document.getElementsByClassName) {
matchingElements = document.getElementsByClassName(id);
} else {
var elements = document.getElementsByTagName("tr");
for (i = 0; i < elements.length; i++) {
if (elements[i].className == id) {
matchingElements[matchingElements.length] = elements[i];
}
}
}
for (i = 0; i < matchingElements.length; i++) {
toggleDisplay(matchingElements[i], obj);
}
}
function toggleDisplay(element, obj) {
if (element.style.display == "none") {
element.style.display = "block";
obj.innerHTML = "<img src=\"../../Images/minus.gif\" border=\"0\">";
} else {
element.style.display = "none";
obj.innerHTML = "<img src=\"../../Images/plus.gif\" border=\"0\">";
}
}
Which works fine, but what I need is something like this: Control 1: Toggle - ROW 1 (+ Close ROW 2 (if visible)) Control 2: Toggle - ROW 2 Is this a Javascript or PHP issue? Hey guys I am having trouble loading a drop down menu list script that I got from Dynamic Drive. Here's the original test page. (Works Fine) <html> <head> <script language="javascript" src="http://www.modbargains.com/images/Javascript/ChainSel/chainedmenu.js"> </script> <script language="javascript" src="http://www.modbargains.com/images/Javascript/ChainSel/MBVehicleChainSelect.js"></script> </head> <body onLoad="initListGroup('Vehicles', document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel, 'savestate')"> <form name="listmenu0"> <table align="center"> <tr> <td><select name="firstlevel" style="width:160px;"></select></td> </tr> <tr> <td><select name="secondlevel" style="width:160px;"></select></td> </tr> <tr> <td><select name="thirdlevel" style="width:160px;"></select></td> </tr> <tr> <td><input type="button" value="Go" onClick="goListGroup(document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel)"> <input type="button" value="Reset" onClick="resetListGroup('Vehicles')"> </tr> </table> </form> </body> </html> HOWEVER! The site I am working on (which is on a different server) does not allow me to alternate the body tag. Is there an alternative way of doing a body onLoad without actually alternating the body tag? I read that you could do a function onload using javascript, so I tried using this: <script language="javascript" > window.onload = initListGroup('Vehicles', document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel, 'savestate'); </script> I am not sure if the function is correct but it does not work. Any ideas how I can make this work???? I have HTML page which use js function and worked fine b4 I pull out the javascripts function from that page. Then later, I created .js file for the js functions and test again, the function doesn't work anymore. In .js file, <script type="text/javascript"> var upload_number = 2; function addFileInput() { var d = document.createElement("div"); var file = document.createElement("input"); file.setAttribute("type", "file"); //file.setAttribute("name", "attachment"+upload_number); file.setAttribute("name", "ufile[]"); file.setAttribute("size", "40"); d.appendChild(file); document.getElementById("moreUploads").appendChild(d); upload_number++; } </script> ************* Then in html page, I put <script language="javascript" src="jsfile/test.js"></script> in the <head> tag and call the function in <body> tag, <div id="moreUploads"></div> <div id="moreUploadsLink" style="display:none;"> <a href="javascript:addFileInput();">Upload another File</a> </div> ******************** When I click on the Upload another file link, nothing appear. It worked b4 I create separate js file. Pls help me solving this problem and gimme suggestions. Thanks in advance! PY Hi, Ok i want to do the following... I am using blogger and I have thousands of posts and each post topic has a specific image assigned to it but every now and then I like to change the image that is being displayed but then I have to go through thousands of posts to change the image URL and this takes super long to complete. I thought of an idea of using Javascript to control this so I need your help please.. I want to be able to have a JS that I can insert the URL's of each image required for the posts and assign an ID like a number or a name to them, then have a seperate JS script that I can insert in ALL my posts and assign the same number to each related post relating to the image ID... So if I need to change images then all I need to do is change the URL in the Javascript and it affects all the posts that contain this image... hope this makes sense.. Please help Thank you. I have seen code like this but it only randomizes the images but is the same concept, perhaps someone can just alter this code for me please...

Hello Friends... I am working on the healthcare project.So in that project there are different html pages for the user interaction & Events,such as user registration,patient profiles,doctor registration. So in the patient registration page i want to add the calendar control the requirement is whenever i click on the calendar control the user selected date is displayed in the textbox in the ddmmyyyy format.. So please tell me the answer... Thanking you..... Umesh I have an ASP.Net page that uses functions in a .js file. I'm trying to reset the values in the controls on the form. The script I'm using works for Text boxes, TextArea boxes, and Check boxes, but, doesn't work for Select-One (DropDownList) or Select-Multi (List) controls. Included is the code. I use the alert() call as troubleshooting to insure the code segment is entered and the control is identified. The SelectIndex of the control is not being set. When this code is hard coded on the page it works. Code: function ClearAllControls() {
for (i = 0; i <= document.forms[0].length; i++) {
doc = document.forms[0].elements[i];
switch (doc.type) {
case 'text':doc.value = ''; break;
case 'textarea':doc.value = ''; break;
case 'checkbox':doc.checked = false; break;
case 'select-one':
doc.selectedindex = 0;
alert(doc.name + " - " + doc.type)
break;
default:break;}
}
}
All, I have some code on my page which changes images in a div without reloading the page. This works great, however my problem comes with I go through a couple images and the actual URL is still on the original image. Is there any way to change the URL when I click the image as well??

I can now work the plugin with javascript to make it stop play pause and fast forward to a song, thing is i cant make it to play another song. in all sources i looked at , this piece of code should be what i am looking for : document.getElementById('movie2').SetQTNEXTUrl(2,'music/myparty.mp3'); well, that in any case wont work for me, then there was another piece of code wich should go in the embed part wich is this: QTNEXT1=myparty.mp3 in firefox it has the effect of opening the myparty.mp3 on another page in wich the quicktime plugin will show but cant find the song, in internet explorer it just simply give's the error "page is ready but with errors". can anyone help me to understand what goes wrong, what would fix it or a simpler way to embed a large amount of songs onto a website? hoping to hear something soon this is the code /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <SCRIPT LANGUAGE = "JavaScript"> function PlayIt(movname) { movname.Play(); } function StopIt(movname) { movname.Stop(); } function rewindIt(movname) { movname.rewind(); } function SetRate(movname,rate) { movname.SetRate(rate); } function SetTime(movname,time) { movname.SetTime(time); } function VolumeIt(movname,v) { movname.SetVolume(v); } document.getElementById('movie2').SetQTNEXTUrl(2,'music/myparty.mp3'); document.getElementByName('movie2').SetQTNEXTUrl(2,'music/myparty.mp3'); document.getElementById('movie2').SetQTNEXTUrl(1,'music/myparty.mp3'); document.getElementByName('movie2').SetQTNEXTUrl(1,'music/myparty.mp3'); </SCRIPT> </head> <body> <embed hidden="false" autostart="true" loop="-1" controls="largeconsole" height="25" width="100"></embed> <body> <br><br> <a href="#" onClick="StartVideo()" ;>startvideo</a><br> <a href="#" onClick="PlayIt(movie2)";>functie</a><br> <a href="javascript:document.movie2.Stop()">Stop</a><br> <a href="javascript:document.movie2.Play()">Play</a><br> <a href="javascript:document.movie2.SetRate(1.0);">SetRate(1.0)</a><br> <a href="javascript:document.movie2.SetRate(2.0);">SetRate(2.0)</a><br> <a href="javascript:document.movie2.SetVolume(100);"> SetVolume(100) </a><br> <a href="javascript:document.movie2.SetVolume(255);"> SetVolume(255) </a><br> <br> <object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" codebase="http://www.apple.com/qtactivex/qtplugin.cab" width="180" height="160" id="movie2"> <param name="src" value="music/camaro.mp3"> <param name="Autoplay" value="false"> <embed width="180" height="160" src="music/camaro.mp3" QTNEXT1=myparty.mp3 name="movie2" enablejavascript="true" autostart="false"> </object> <br> <SCRIPT LANGUAGE = "JavaScript"> document.getElementById('movie1').SetQTNEXTUrl(2,'music/myparty.mp3'); document.getElementByName('movie1').SetQTNEXTUrl(2,'music/myparty.mp3'); document.getElementById('movie2').SetQTNEXTUrl(2,'music/myparty.mp3'); document.getElementByName('movie2').SetQTNEXTUrl(2,'music/myparty.mp3'); </SCRIPT> <br> <br> http://userwww.sfsu.edu/~infoarts/te...avascript.html </body> </html> /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Hi All, I have a select html control as below ; <SELECT > <OPTION VALUE="1"> This is option 1 </OPTION> <OPTION VALUE="2" >This is option 2 </OPTION> <OPTION VALUE="3" >This is option 3 </OPTION> </SELECT> My requirement is that when user moves pointer over the items the value of the item should be shown in a hint box. How could I show the value of the item in a hint box as user moves pointer over an item using javascript? Thanks, Dev Firstly let me say, im relatively new to Javascript so im still picking things up.. I have a website that i want to add several mp3's onto. When a user clicks a link i wanted to make javascript change the streaming audio to the one that was selected. My HTML is as follows.. Code: <table style="background-color:Black; color:gold; font-weight:700; font-size:16px">
<tr onClick="Click('http://www.m-hops.co.uk/Music/Motown Flavours.mp3')"><td>
1. Motown Flavours
</td></tr>
<tr onClick="Click('http://www.m-hops.co.uk/Music/All_Around_The_World.mp3')"><td>
2. All Around The World
</td></tr>
<tr><td>
<OBJECT ID="MediaPlayer" WIDTH="290" HEIGHT="50"
CLASSID="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95"
STANDBY="Loading Windows Media Player components..."
TYPE="application/x-oleobject">
<PARAM id="TRACK" name="FileName" value="http://www.m-hops.co.uk/Music/Motown Flavours.mp3">
<PARAM name="autostart" value="true">
<PARAM name="ShowControls" value="true">
<param name="ShowStatusBar" value="true">
<EMBED id="sound" TYPE="application/x-mplayer2" src=""
NAME="MediaPlayer" WIDTH="290" HEIGHT="50" ShowControls="1" ShowStatusBar="1" autostart="1">
</EMBED>
</OBJECT>
</td></tr>
</table>
and my Javascript is.. Code: <script language="javascript" type="text/javascript">
function Click(track)
{
document.getElementById('TRACK').value = track;
window.alert(document.getElementById('TRACK').value);
}
</script>
It appears that the right track is being parsed to the javascript but its not changing the audio thats being played. Any ideas?? Hi, Is it possible that when a webpage loads I can have javascript change the class of a div from: .up { transform: translate(0px,-500px) transition: all 5s ease-in; } to .down { transform: translate(0px,0px) transition: all 5s ease-in; } Essentially I would like a div to move down into place from the top of screen to the middle of screen after the page has loaded. Some thing like this?: Code: <script type="text/javascript">
function transform()
{
document.getElementById("content").className = "down";
</script>
<div id="content" class "up" onload="transform()">
</div>
</html>
would this work or is there a better way? Adrian. Hello, i am doing a test right now. What i have done is 1. A Counter/Timer That Counts until Zero 2. A Button that appears when the counter is Zero When I Click the Button it executes this code in the address bar (Navigates): javascript:gonow(); The id of the Timer: count What i want? When the Button appears, it will be clicked automatically... i started doing a different code, when the timer = 0 to navigate at javascript:gonow(); but it didnt worked.... See my code he Code: function AutoClick(){
var timer = document.getElementById(count);
if(timer.value=0)
unsafewindow.gonow();
}
Tried to explain as more as i could, now im waiting for an answe, dont dissapoint me please. Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. Help will be greatly appreciated! Situation: I have a very long page divided into many sections vertical-wise marked by bookmarks, say pageX.html#s1 to s10. I need to show the section inside an iframe (iFrame1) on the mainpage (mainpage.html). I am thinking of having 4 buttons, sitting on the mainpage, to help navigate between these sections on pageX, namely NEXT, PREVIOUS, TOP, END. condition of the frame, fixed width/height, no scroll, no border. Very new to javascript but need this code to make a page work for BIZ. Thank you in advance for anyone kind enough to point the right direction! |
