JavaScript - Fire Javascript From <a Href>
Hello
I am trying to display an image (url stored in a variable) in an iframe, and write some text (which is also stored in a variable) to a div when the user clicks on another image. (hope that makes sense!) The image display part works fine, but I cant find out how to make the part of my javascript which writes the text work. My code is below, I think the problem is to do with the OnClick event but I'm not sure. Any help you can offer might save what little hair I have left! [CODE] ******************************************** This script displays the image in the iframe <script type="text/javascript"> function fitTable(Jvar) { var swidth1= window.innerWidth-230; var sheight1= window.innerHeight-170; var swidth2= document.body.clientWidth-200; var sheight2= document.documentElement.clientHeight-170; if(window.innerWidth) { //checking for browsers that support window.innerWidth document.getElementById("divone").style.width = swidth1 + "px" document.getElementById("divone").style.height = sheight1 + "px" } else if (document.body.clientWidth) { //checking for browsers that support document.body.clientWidth document.getElementById("divone").style.width = swidth2 + "px" document.getElementById("divone").style.height = sheight2 + "px" } var txt=document.getElementById("divdescr") txt.innerHTML="Some Content"; } window.onload=fitTable; window.onresize=fitTable; </script> **************************************** This script writes the text in the div <script language=javascript> function swDescrip(Jvar) { document.getElementById('divdescr').innerHTML = Jvar;} </script> ****************************************** This is the ASP code: <% RS.MoveFirst For d = 1 to recs %> <div ID=d> <% ***************************************************** What I really want is for this bit to display the image in the iframe AND write the text into the div when I click the image in RS(2) desc(d) = "<p>" & RS(1) & "</p>" Response.Write "<A HREF=" & RS(3) & " target='iframe'><img src=" & RS(2) & " width=200 height=120 border=0 onClick = javascript:swDescrip(" & desc(d)) & ") alt='click to display photo' /></a><br>" ****************************************************** %> This bit works OK if I click it but its not what I want <a href="javascript:swDescrip('<%= desc(d)%>')">click</a> ***************************************************** </div/> <% d = d+1 RS.MoveNext Next %> Similar TutorialsI've built a site which involves some cool scrolling effects via javascript. I tested it in Chrome, Firefox, Safari, Opera and IE8. Worked Perfectly. Then, I try IE7, and its a dud. Tried from multiple computers, so it is an IE7 issue. Here's the issue. When the page loads normally, a flash intro plays and then the menu shows up. When you click on a menu option (only products and services work), it scrolls the image/layer inside of the div to the proper layerID. (so far, I only have products and services working.. ) When you click on the menu option in IE7, or earlier I'm guessing, It just scrolls to the menu image slice, not the proper layerID it calls for. Heres the link: www.designbyryanboog.com/spa Sorry about not posting code, but there is a lot. I appreciate ANY help, thanks! Hi all, Please keep in mind: this is the first code I have ever written -- much of it with help from this forum and the skeleton from other corners of the JS community. Thanks! But now for the problem... I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax. I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income. Any ideas? Thanks in advance. Code: <script language="javascript" type="text/javascript">

Hi, I am trying to write some code (not my main function in my job) to have a variable be inserted in the middle of a "<a href>" tag. I created an XML file and I am parsing it with XSL and that is working well. In my XSL code I have the following (and it is working): Code: <xsl:for-each select="documents/data[frequency='Daily']"> <script>var meetingIndicator = <xsl:value-of select="meetingIndicator"/>; </script> <tr> <td class="tableLink"><a href="" onMouseover="showmenu(event,linkset[0], '450px')" onMouseout="delayhidemenu()"><xsl:value-of select="meetingCategory"/></a><script>document.write(meetingIndicator);</script> </td> <td><xsl:value-of select="meetingCategory"/></td> <td> <xsl:value-of select="duration"/> </td> <td> <xsl:value-of select="purpose"/> </td> <td> <xsl:value-of select="idealFor"/> </td> <td> <xsl:value-of select="instructions"/> </td> <td class="tableLink"> <a><xsl:attribute name="href"> <xsl:value-of select="documentURL"/></xsl:attribute> <xsl:value-of select="supportingDocuments"/></a> </td> </tr> </xsl:for-each> </table> In this part of the code: Code: <td class="tableLink"><a href="" onMouseover="showmenu(event,linkset[0], '450px')" onMouseout="delayhidemenu()"><xsl:value-of select="meetingCategory"/></a><script>document.write(meetingIndicator);</script> I want to replace the 0 in (event,linkset[0], '450px') with the "meetingIndicator" variable (or even the "<xsl:value-of select="meetingIndicator"/>;") but I don't know how to. I can call the "<xsl:value-of select="meetingIndicator"/>;" and it displays the correct value from the XML file. i just need to know how to place that in the "event,linkset[0]" part of the "a href" tag. I guess it is going to be pretty easy but I have been googling and playing it since yesterday and i am not having any luck. Thank you. is it possible to link to a page and then run a javascript all in the same href? for example, i want to redirect back to the home page after a user makes a comment and show the hidden comment div this is my javascript command: Code: <a href="javascript:InsertContent('competitiveevents'); RemoveContent('stories'); InsertContent('blog-comments');">
but can i do something like this..? Code: <a href="../index.php:javascript:InsertContent('competitiveevents'); RemoveContent('stories'); InsertContent('blog-comments');">
Hi, I am trying to add one image in footer of my application. Code: <div class="rightLinks"> <a href="#"><script src=https://seal.somesign.com/getseal?host_name=www.validsite.com&size=S&use_flash=NO&use_transparent=NO&lang=en></script></a> </div> But this is not working. Please let me know, what is wrong in it. And how can we correct it. Thanks!! Regards, Neha Hi, I am making a link to the current url and adding ?XXXX to the end of the URL. I have done this like so: Code: <UrlAction Url="javascript:q=(document.location.href);void(open((q)+'?XXXX,'_self','resizable,location,menubar,toolbar,scrollbars,status'))"/> This works perfectly. However I need to add an If statement in this code which does the following: If (there is a ? already in the current url) add &XXXX instead. Can anyone help me add this in? Thanks I have a page that loads various "applications" into an iframe inside the main page. One of the applications loaded calls a javascript function that is loaded with the "application" page. It works great in Safari, Chrome & Firefox but error's out in IE8 - "Object doesn't support this action". Anyone know why ? Have other calls that work but this one is the only one that uses href Thanks, JerryB [CODE] <div id = 'trainingsubmitbutton' style='display:none;'><a href='javascript: submitdata(0)'>Submit This Record</a></div> [CODE] Hi, I'm using the following Javascript code to show a div layer depending on the URL Code: <script type="text/javascript">
if (location.href.match(/folder/)) {
document.getElementById("div-layer").style.display="block";
}
</script>
This works perfectly when I visit http://www.domain.com/folder but I do not want it to match any subfolders beneath /folder, for example: http://www.domain.com/folder/sub-folder http://www.domain.com/folder/sub-folder2 etc. Does anyone know how I can modify the code to only match /folder or /folder/ and no subfolders beneath it? Thank you in advance. I'm using <base href> to set my HTML path for links, and chdir() to set PHP's base path. (Entering site at www.mysite.com/account then resetting my paths back to root for simplicity). Both of these are working fine, however I've found Javascript ignores <base href> so it's working directory is still a subfolder of root. OK - so I could add '../' to all Javascript links (which is what I was trying to get away from!) but I've read that it's only IE that ignores <base href> and other browsers accept it. This will mean my links break unless I either stop using <base href> entirely and go back to using '../' in ALL links, or I can find a way to set Javascript's base link pointer... This is driving me crazy! Any ideas of how to do it? I'm trying to get a select box to populate onload but can't get it to go. It works fine onchange. This populates the city select box from my db depending on what state is selected. Here are the functions: Code: function handleOnChange(dd1)
{
var idx = dd1.selectedIndex;
var val = dd1[idx].text;
var par = document.forms["cbcheckedadminForm", "adminForm"];
var parelmts = par.elements;
var cb_citysel = parelmts["cb_city"];
var state = val;
var directory = ""+document.location;
directory = directory.substr(0, directory.lastIndexOf('/'));
Http.get({
url: "./components/com_helloworld/js/regvalues/" + state + ".php",
callback: fillcb_city,
cache: Http.Cache.Get
}, [cb_citysel]);
}
function fillcb_city(xmlreply, cb_cityelmt)
{
if (xmlreply.status == Http.Status.OK)
{
var cb_cityresponse = xmlreply.responseText;
var cb_cityar = cb_cityresponse.split("|");
cb_cityelmt.length = 1;
cb_cityelmt.length = cb_cityar.length;
for (o=1; o < cb_cityar.length; o++)
{
cb_cityelmt[o].text = cb_cityar[o];
}
}
else
{
alert("Cannot handle the Ajax call.");
}
}
And here's how I'm trying to do the onload: Code: function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
ajaxFunction(document.getElementById('country').value);
});
addLoadEvent(function() {
setupDependencies('cbcheckedadminForm', 'adminForm', 'locationsearch');
});
addLoadEvent(function() {
handleOnChange(dd1);
});
addLoadEvent(function() {
fillcb_city(xmlreply, cb_cityelmt);
});
I've tried variations of handleOnChange(cb_state), handleOnChange(document.getElementById('cb_state'), handleOnChange(ydntuwrkupceofcrp), I've tried chaining the 2 functions together, but nothing I do seems to get this to work. What am I missing here? I have created a Blackjack program. I have noticed that clicking on the vertical part of the 'D' on the "Deal" button doesn't always fire the onclick event. I use JS to change the div's style when clicking on it to give the appearance of a normal button. Here's the link: http://www.myfsjournal.com/blackjack/index.php username: test password: test Here's relevant code: HTML: Code: <div id="dealButton" style="position:relative;float:left;width:100%;z-index:10;">
<div id="deal" title="Deal" style="cursor:pointer;background:#CCC;padding:3px;width:75px;height:auto;border-top:1px solid;border-left:1px solid;border-bottom:3px solid;border-right:3px solid;" onclick="window.location = 'index.php?a=deal'" onmousedown="javascript:buttonDown('deal');" onmouseup="javascript:buttonUp('deal');" onmouseout="javascript:buttonUp('deal');">
Deal
</div>
</div>
And my JS code: Code: function buttonDown(id)
{
document.getElementById(id).style.borderBottom = "1px solid";
document.getElementById(id).style.borderRight = "1px solid";
document.getElementById(id).style.borderTop = "3px solid";
document.getElementById(id).style.borderLeft = "3px solid";
}
function buttonUp(id)
{
document.getElementById(id).style.borderBottom = "3px solid";
document.getElementById(id).style.borderRight = "3px solid";
document.getElementById(id).style.borderTop = "1px solid";
document.getElementById(id).style.borderLeft = "1px solid";
}
How can we fire/invoke ondragstart diagrammatically in Mozilla?
I am registering the ondrag event handler on mousedown event as follows: td.addEventListener("drag", MyMethodName, false); But the drag event fires only if I select the entrie Td with mouse and not when right click over td and try to drag. My browser is mozila. Any ideas on this one? Greetings. I am using an image galery script written by another person - frogjs (http://www.puidokas.com/portfolio/frogjs/) This script is showing current pic in the middle of the screen and next/previous little tumbnails on right/left sides of the current. When you click the next pic, current pic is zoomed out to the left and next pic is zoomed in to the middle, then replaced by a full-size pic. Then a new tumbnail appears on the place of the next pic you clicked. Zooming and stuff is done with another thirdparty script "effects" (script.aculo.us effects.js v1.7.0) My problem is, the actual next tumbnail is not being shown until the big image is preloaded for this thumbnail. This is done to make it look smooth. So, when i click "next" picture, the next picture is shown, but switching to the following one is delayed until that following one is actually loaded. It is done by making an imgpreloader=Image() object and setting imgpreloader.onload to a function, then setting imgpreloader.src to the big image path. The big image then is supposed to be automatically loaded by browser. When its done, an onload event should fire and that should execute the function that shows the thumbnail for the big picure. Problem is, sometimes the onload event won't happen! And since it wont happen, my gallery will "stall" - it will never show next thumbnail and never allow to continue viewing. And if i show next thumbnail immediately, the next picture would be shown partially and that does not look good. Moreover, i've seen numerous image galeries on numerous sites and all of them seem to work with onload because i only see the image when its loaded, until that i see some "wait" or "grey screen" thing. Never had a problem with those stalling. Problem happens mostly with Opera and Chrome and happens seldom with IE. So, question is, do you probably know what can prevent browsers from firing and OnLoad event or from loading a picture when its suppied as an src for an Image() object? Do you know a workaround that can "poke" the browser to remind it to get the damn picture again and not to stall. I have an aspx with javascript, and I used to call a script func whenever the page was loaded. Suddenly it doesn't work. I then tried to simplify things to <body onload="alert('hello');" and no alert is shown, nor do I get any error. How come the onload event doesn't fire? How do I fix it? thanks in advance I am creating a popup for an online store so that when prospective customers put something in their shopping cart and then try to leave the site, they are offered a coupon in a popup. I am using the following code (FYI, uses prototype.js) Code: Event.observe(document.body, 'click', function(event) {
if (Event.element(event).tagName == 'A' || Event.element(event).tagName == 'INPUT' || Event.element(event).tagName == 'IMG') {
staying_in_site = true;
}
});
window.onbeforeunload = popup;
function popup() {
if (staying_in_site) {
return;
}
if (popup_displayed) {
return;
}
popup_displayed = true;
//popup displayed here
}
The popup is not displayed when the user clicks on a link or submits a form (correct behavior) and it is displayed when the user types in a URL or tries to close the browser (also correct behavior). The problem is when the user clicks the back or forward buttons, the popup is displayed which is not the desired behavior. Anyone here have a solution for this? Hi I have a problem where I have a drop down menu above a flash banner. The drop down is being hidden by the banner when you hover over it. I added the following to stop that <param name='wmode' value='transparent'>. Its working fine in IE 6 where the drop down options are over the banner but it wont work with IE7/8 or firefox. Any suggestions for code that will work for all browsers? Code: document.write("<object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0' width='381' height='130'><param name='allowScriptAccess' value='sameDomain' /><param name='movie' value='/content/images/flash/abc.swf'><param name='quality' value='high'><param name='wmode' value='transparent'><embed src='/content/images/flash/abc.swf' wmode='transparent' quality='high' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' width='381' height='130'></embed></object>");
Hi, I'm having some problems with some javascript events firing in the wrong order under certain workflows. Here's the gist of it: I have a form with many fields, mostly input type = text. Each field as an OnBlur and OnFocus event tied to javascript functions. IE's website (http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx) states that "The onblur event fires on the original object before the onfocus or onclick event fires on the object that is receiving focus." and that is exactly what happens when tabbing through the fields. The tricky part is that it doesn't perform this way when CLICKING to another field. When clicking to another field it performs the new field's OnFocus first, and then the first field's OnBlur event after. This is bad because the OnFocus sets a global variable's value to whatever value is in that box at the time it gets focus and if the onblur validation fails, that value is inserted back into the box. So what's happening is the validation for field 1 fails and the value from field 2 is then written into field 1. This also seems to only happen when the page is opened as a modal window as opposed to just opening the page on it's own. It doesn't happen in FireFox, I've only been able to get it to happen on IE 8 + (haven't tried any other browsers.) Anyone else have this happen to them? Does it sound like an IE bug? Thanks **just realised I have put this in the wrong section
