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. 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">
function TotalGrossPerYear() {

It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi room, Hey, I opened up the source code for this page in google chrome and since i'm learning javascript, i wanted see if i could "read" it and figure out what was going on. I'm am having the hardest time understanding "return false" and "return true". Could someone step me through this via interpreting this code (in bold typeface): Code: var DefaultValue = 'Search';
function clearSearch() {
if (document.searchForm.q.value == DefaultValue) {
document.searchForm.q.value = '';
}
}
function validateSearchHeader() {
if ( document.searchForm.q.value == '' || document.searchForm.q.value.toLocaleLowerCase() == DefaultValue.toLocaleLowerCase() ) {
alert('Please enter at least one keyword in the Search box.');
document.searchForm.q.focus();
return false;
}
return true;
}
Thanks! 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();}
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" );
}
function emitApplet() {
document.write("<APPLET CODE=\"mytest.class\" archive=\"mytest.jar,netscape.jar\" NAME=\"myApplet\" MAYSCRIPT HEIGHT=1000 WIDTH=1000> </APPLET>");

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! (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()
}
~read that focus() should do it . . . but it doesn't Thanks! 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? 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 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> 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. If you can help - many thanks Hello, I have a search textbox field which populates the results in a dropdown after searched.

Hey Guys, I am currently building a web app that uses Google Maps V3 api. You select a check box which then shows a marker on the map. My issue is, when you select and the marker is placed, I need the map to focus to that point, it currently embeds but doesn't focus. Is there a particular function I could use to achieve this? My current code is shown below: Code: var locations = [
// Longitude, Latitue, Content, Country Code, City Name
[51.481383, -3.114967, holidayOverlay, 'UK', 'Cardiff'],
[52.362393, 4.893379, holidayOverlay, 'NL', 'Amsterdam'],
[48.852314, 2.350089, holidayOverlay, 'FR', 'Paris'],
[40.18884, -3.716812, holidayOverlay, 'SP', 'Madrid'],
[53.800651, -4.064941, holidayOverlay, 'IT', 'Rome'],
[42.041134, 1.889648, holidayOverlay, 'SP', 'Costa Brava'],
[36.79334, 27.234421, holidayOverlay, 'GR', 'Kos'],
[37.014581, -7.933888, holidayOverlay, 'PT', 'Algarve'],
[28.358776, -14.05426, holidayOverlay, 'PT', 'Fuerteventura'],
[29.046854, -13.589973, holidayOverlay, 'SP', 'Lanzarote'],
];
// Only create marker when checked
for (i = 0; i < locations.length; i++) {
if (locations[i][4] == location) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][0], locations[i][1]),
map: map,
icon: plotImage
});
var title = locations[i][4];
var content = locations[i][2];
}
}
I have left a lot of the code out to save you a headache. Thanks. Let say I typed the word "Red", on input type text, is it possible with Ajax or Javascript to auto focus (highlight) the word "Red" on the select drop down list. I am looking at the net, but I can't find a code that does that. <input type="text" /> <select name=""> <option> Blue </option> <option> Red </option> <option> Green </option> </select> Is there a way to give an input or textarea field the focus and set the focus to begin right at the end of the current text in the field?
currently i have the script as below which open the link in new tab but also shifts the focus to it...how do i keep the focus on the parent window PHP Code: <script type="text/javascript"> function openlink(url) { window.open(url); return false; } </script> <div class="btn" onclick="openlink()">Open Link</div> |
