JavaScript - Focus And Jump
Hi,
I need your help guys. I've got a little problem. I have some smileys which I enter to a textarea when clicking on them. It works perfect, but once the user clicks on a smiley, the focus goes off of the textfield. I use document.getElementById('message').value += smileycode It works perfectly, it enters the smileycode to the textarea. My problem is... When I say document.getElementById('message').focus() it goes back to where the cursors has last been so before the smileycode. Instead of this, I want the focus to go back after the insertion of the code. I hope it's understandable. And thanks in advance! Similar TutorialsHi I'm banging my head against this problem and I'd really appreciate some help. I think the problem is cause by my lack of understanding of how the browser (firefox 3.6.3) handles focus. A simplified version of my problem is: I've defined the function Code: function two_focus()
{
document.getElementById("two").blur();
alert("hello");
}
then in the body I have the form with two text boxes Code: <input id="one" type="text"><input id="two" type="text" onfocus="two_focus();"> When the page is loaded and I click in the second textbox I get the alert, all well and good. I OK the alert box, but when I click on box 1, or anywhere on the page for that matter, the function is called and the alert comes up. I just don't understand why the focus is being returned to the second box when I click anywhere in the browser window. Any comments will be gratefully received. I am using a Jump Menu: Code: function MM_jumpMenu(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}
function MM_findObj(n, d) { //v3.0
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); return x;
}
function MM_jumpMenuGo(selName,targ,restore){ //v3.0
var selObj = MM_findObj(selName); if (selObj) MM_jumpMenu(targ,selObj,restore);
}
Code: <form name="FrontPage_Form1" language="JavaScript" onsubmit="return FrontPage_Form1_Validator(this)">
<!--webbot bot="Validation" b-disallow-first-item="TRUE" --><select name="menu" class="TextArea" onchange="MM_jumpMenu('self',this,0)">
<option value="javascript:myVoid()" selected>Choose One
</option>
<option value="1.html">One</option>
<option value="2.html">Two</option>
</select>
</form>
Is there some way to make such a jump menu observe the history, so that going back will go back to the page containing the form? Hello all, I needs some help. I currently have a script to jump to an anchor tag when the page loads: Code: <script type="text/javascript">
function goToAnchor() {
location.href = "myPage.html#myAnchor";
}
</script>
Now, I would like to take it a step further and would like to link from page A to page B that usually takes a while to load and once the page loads, run a script to jump to the specified anchor tag on the page after everything has loaded. I know I have to add some parameters at the end of the url link on page A, but that's where I get stuck. Can anyone please help? Right so I have a popup window that when opened in any browser expect of course IE will open perfectly in the centre of the screen. However with IE it decides to jump to the top of the page, then is pushed back down to just show the popup at the bottom of the window. Anyone got any idea how I can stop this? Using IE8. Code: function openPopup_JD(params){
var name = params.name;
var blanket = params.blanket || true;
var effect = params.effect || "fade"
var afterOpen = params.afterOpen || "";
var width = document.getElementById(name).style.width;
var height = document.getElementById(name).style.height;
width = width.slice(0, -2);
height = height.slice(0, -2);
width = width * 1;
height = height * 1;
document.getElementById(name).style.left = getLeft_JD(width) + "px";
document.getElementById(name).style.top = getTop_JD(height) + "px";
//Create blanket if it doesn't already exist.
if(!document.getElementById('blanket')){
var popupBlanket = document.createElement("div");
popupBlanket.id = 'blanket';
popupBlanket.style.display = "none";
popupBlanket.style.opacity = 0;
popupBlanket.style.filter = 'alpha(opacity = 0)';
popupBlanket.style.backgroundColor = "#000";
popupBlanket.style.position = "absolute";
popupBlanket.style.zIndex = 9998;
popupBlanket.style.top = "0px";
popupBlanket.style.left = "0px";
popupBlanket.style.width = "100%";
popupBlanket.style.height = getBlanketHeight()+"px";
document.body.appendChild(popupBlanket);
}
switch(effect){
//-----------------------------------
//FADE IN
//-----------------------------------
case "fade":
if(blanket == true){
animate_JD({
objects: 'blanket |'+name,
properties: "opacity |opacity",
start: "0",
end: "0.75 |1",
inerval: "20 |20",
frames: "15 |20",
effect: "SFS",
wait: "0 |-1",
onStart: "toggle('blanket') |toggle('"+name+"')",
onComplete: " |"+afterOpen
});
}else{
animate_JD({
objects: ''+name,
properties: "opacity",
start: "0",
end: "1",
interval: "20",
frames: "6",
effect: "SFS",
wait: "0",
onStart: "toggle('"+name+"')",
onComplete: ""+afterOpen
});
}
break;
Not all of the function is shown because below this are only other effects if i have a large script built multi-select-list-box, is there a way within javascript to onClick of a hyperlink, jump-to the line within the select box that corresponds to the value clicked?
Hi all, I am having trouble with the Form Validation I have on my wifes website...everything is working how it should it's just when you hit the submit button the screen jumps up about an inch or so putting the error message out of view....Is there anything that can be done to stop... Thanks all. Hello I need some help with Google Maps please. Im using Google Maps API V3. So I can create a simple map but what I need is to have two markers (which are quite far apart) on the map. For example these markers are called 'Marker 1' and 'Marker 2'. Below the map I would have 2 links called for example 'Marker 1 link' and 'Marker 2 link'. When the map loads, 'Marker 1' is visible and centered. Now to move to 'Marker 2' on the map, I would click the link under the map. And vice versa. A good example is http://arts.brighton.ac.uk/contact-u...aculty-of-arts I tried but failed when I tried this guys answer on this website: http://stackoverflow.com/questions/2...utside-the-map Any help to create this is greatly appreciated! Hi all, I'm having problems with a javascript jump menu that uses two select form elements, where the first one enables the second one if the right option is picked. I've not much knowledge of javascript so I've basically combined two separate functions, but at the moment only the second menu redirects the user - I need the first menu to do this as well if the second option is selected. Any ideas?! Here's the code - many thanks in advance if you can help: Code: <html>
<head>
<script type="text/javascript">
function chooseSelect(selectOption) {
document.getElementById('shape').disabled = (selectOption!=1);
}
function jumpMenu(select) {
var i = select.selectedIndex;
var selection = select.options[i].value;
var url;
if (i === 0) {
alert("Please select an option");
} else {
url = selection;
location.href = url;
}
}
</script>
</head>
<body>
<form action="" method="get">
<select name="color" id="color" onChange="chooseSelect(this.value);">
<option value="">- Choose Color -</option>
<option value="red.html">Red</option>
<option value="1">Shape</option>
</select><br />
<select name="shape" id="shape" disabled="disabled">
<option value="">- Choose Shape-</option>
<option value="square.html">Square</option>
<option value="circle.html">Circle</option>
<option value="rectangle.html">Rectangle</option>
</select><br />
<br />
<input type="button" value="GO" onclick="jumpMenu(this.form.shape);">

Hi, I want my page to jump to a different page based on data collected in the form input fields. I can jump to a new page alright, using the following javascript: 1. javascript code in form_a.html document.forms["form_A"].action = "page_x.html"l; document.forms["form_A"].submit(); 2. document.forms[0].action = "page_x.html"l; 3. window.locaton = "page_x.html"; 4. window.location.href = "page_x.html"; The problem is, I can see the new page was jumped to, but immediately it return back to the page that trigger the jump. Any idea? I need to finish the project before Christmas. Any help is greatly appreciated! Jeff I am displaying a webpage from external domain in an iframe on my site. The webpage being shown in iframe has a header image that I would like to not appear when someone visits my site. Is it possible using Javascript or otherwise to have the iframe scrolled down by a certain pixels by default?
Everything up until the focus line works, any ideas? Code: else {
alert ("Please enter your Postcode correctly, this includes:\n \n * Correct Spacing - AA1 1AA \n * Correct amount of letters and numbers. \n \n Sorry if this causes any inconvenience, but it is to your benefit.");
document.delAdd.postcode.value = "";
document.delAdd.postcode.focus();}
I've got a div named "iframe_container". Inside it are an iframe used to display floor maps and another div named "compass_rose". I have a function that moves compass_rose around the map based on an office number. Now iframe_container is scrollable, it's only big enough to display about 2/3 of the map at any one time. I designed it that way to properly fit in the sharepoint site it's going in. To help some of our less tech savvy users it would be nice if iframe_container would automatically shift its view to keep the compass_rose visible at all times. Can that be done? Thanks. <div id="iframe_container" style="width:1000px; height:635px; position: relative; overflow:hidden"> <div id="compass_rose" style="top: 10px; left: 10px; position: absolute; z-index: 2; visibility:hidden;"><img alt="Compass Rose" src="compass_rose_animated2.gif" width="80" height="80" /></div> <iframe id="viewer" width="1600" height="635" src="front_page2.jpg" marginwidth="1" marginheight="1" name="viewer" scrolling="no"></iframe> </div> I've got an older style frameset (3 frame within). Its a user browse/select set. Top frame is controls, middle is headings & sort control, bottom is the scrollable browse data. This needs a performance solution since it works fine when the browse data is low volume (or the network is blazing fast). The prob: Once the set is fully loaded the cursor is placed in a text box in the control frame allowing the user to be able to type a search term without having to click in the textbox. Problem is the cursor doesn't stick in the bottom frame after _all_ that data loads I tried: Code: window.parent.MCABrowseControl.document.getElementById('txtQuickFind').focus()
alert("after")
no errors of any kind and for a split second the cursor is visible -- and then is gone (the focus appears to revert to the bottom frames first input (a radio button) I messed with onreadystatechange but couldn't get my fx to fire when the state became "complete". It only fired once when "loading" Any methods/properties I can use to solve the issue of _waiting_ for all frames to finish before setting the focus(), and have it stay there? thanks (sorry for the noobiness) Is there a way to focus on the most recent input to a text area (say after 50 inputs) without having to manually scroll down?? Code: function console(msg){
document.console1.input.value = document.console1.input.value+=msg
document.console1.input.value.focus()
}

Hy ! I have this form: PHP Code: <form name = "myform" method = "POST" action = "proba1.php"> Name:<br /> <input type = "text" name = "name" size = "30" onBlur = "namecheck()" /><br /> Username:<br /> <input type = "text" name = "username" size = "30" onBlur = "usercheck()" /><br /> Password:<br /> <input type = "password" name = "password" size = "30" /><br /> Repeat password:<br /> <input type = "password" name = "password2" size = "30" onBlur = "passcheck()"/><br /> Email:<br /> <input type = "text" name = "email" size = "30" onBlur = "mailcheck()" /><br /><br /> <input type = "reset" name = "reset" value = "Reset" /> <input type = "submit" name = "submit" value = "Submit" /> </form> and a Js file to check it: PHP Code: function namecheck() { var name = document.myform.name.value; if(name.indexOf(" ") < 0) { document.myform.name.focus(); document.myform.name.select(); alert("Pleaase enter your full name!") return false; } return true; } function usercheck() { var username = document.myform.username.value; if(username.length < 6) { alert("Username must be at least 6 chars!"); document.myform.name.focus(); document.myform.name.select(); return false; } return true; } function passcheck() { var password = document.myform.password.value; var password2 = document.myform.password2.value; if(password != password2) { alert("The two passwords not identical!") } } function mailcheck() { var mail = document.myform.email.value; var diff = mail.lastIndexOf(".") - mail.indexOf("@"); var diff2 = mail.length - mail.lastIndexOf("."); if(mail.indexOf("@") < 0 || mail.indexOf(".") < 0 || diff < 2 || diff2 > 3) { alert("Not a valid email adress!") } } So when a value is not proper,there should be an alert message,then select and focus on the field.But only the alert works.I can set the select and the focus to any other field from the current one ,but not to the current.(For instance:if the name is not good:document.myform.username.select() works,but :document.myform.name.select() not.) Can somebody help me? Hello, I am researching an issue in a rather big app which displays pdf files in IE window. The issue is that inside javascript code we call 'window.setTimeout( win.focus() ...)' (for the child window), but it doesn't come into focus every time, seems a bit random when it does and does not come into focus. At present I wrote a much smaller app + javascript to reproduce the issue, but it does not manifest in same way. Specifically this is the confusing part: window.setTimeout( function() {win.focus(); win.moveTo( 200 , 200 ); } , 500 , "JavaScript" ); the 'win' does move, but never comes into focus. Any ideas about why the focus function does not accomplish what I'm trying to do? Here's the code of my simplified app + html + javascript: JAVASCRIPT: Code: var win;
function f(s) {
website="http://machine/apache/jsfnu/mytest" + s + ".txt";
if (!win)
win = window.open( website , "thetest" , "toolbar=yes,resizable=yes");
else
{
win.url = website;
}
win.navigate(website);
win.focus();
window.setTimeout( function() {win.focus(); win.moveTo( 200 , 200 ); } , 500 , "JavaScript" );
}

Hi I am opening a child window with the following href. If it is a completly new window, it is opened and the focus shifts to it, ... but ... if that href has been clicked on before and the window exists, the focus stays with the parent window and does NOT shift to the child How can I make the focus shift ? here is my href: PHP Code: echo "<a href='$Ad_detail' rel=\"external\" onclick=\"window.open (this.href, '$Ad_detail', 'height=800,width=960,scrollbars'); return false\" > I guess I need a "window. ??? focus();" in there somewhere - but I don't know what the ??? should be.
