JavaScript - How To Stop Double Booting?
Hey I am almost done with my API boot system and with the way I am calling new files it seems to double boot how can I stop this from happening as the page fully loads and that but the loader shown in the IE tab doesn't stop and it says '1 item remaining' and that never goes, both stay until you click anywhere on the document, so I was wondering if there is a way to stop this.
My code to call the js document in the file 'boot.js'. Code: var o = 'http://www.example.com/file.js';
document.write("<script src=\""+o+"\" type=\"text\/javascript\"><\/scr"+"ipt>");
And in index.html I have this script tag Code: <script type="text/javascript" src="http://www.example.com/boot.js"></script> Similar Tutorialshere is where the code is. http://simplythebest.net/scripts/DHT...script_15.html I need this to be able to open in the parent window not in another window. Or if someone could precribe a double drop box that works in "moonfruit" that would be great. Thank you very much for your time. David the following javascript code is for a page that has to different login sections (username and password) hospital admin i want them to login in their part using normal IDs(numbers) and password, and normal users to login in the other login boxes (using email address and password) , each login boxes have their own submit button. the problem is i can't check each of them alone. what i want to do is that if (for user) email and password entered and pressed his login button, to be headed to another page, while if hospital admin entered his id and password in his section and pressed login button, to be headed for a different page. help please ! Code: window.onload = initForms;
function initForms() {
for (var i=0; i< document.forms.length; i++) {
document.forms[i].onsubmit = function() {return checkFields();}
}
}
function checkFields(){
if(document.getElementById("userLogin").onclick)
{
if(isEmail(document.getElementById("userUsername").value)==false)
{
alert("Please enter a valid e_mail address.");
document.getElementById("userUsername").focus();
return false;
}
if(document.getElementById("userUsername").value=="")
{
alert("Please enter your e_mail address.");
document.getElementById("userUsername").focus();
return false;
}
if(document.getElementById("userPassword").value=="")
{
alert("Please enter your password.");
document.getElementById("userPassword").focus();
return false;
}
}
if(document.getElementById("hospLogin").onclick)
{
if(document.getElementById("hospUsername").value=="")
{
alert("Please enter your ID.");
document.getElementById("hospUsername").focus();
return false;
}
if(document.getElementById("hospPassword").value=="")
{
alert("Please enter your password.");
document.getElementById("hospPassword").focus();
return false;
}
}
}
function isEmail(mail) {
var char1 = mail.split("@");
var y = mail.indexOf("@", 0);
var e = mail.indexOf(".", 0);
var w = mail.lastIndexOf(".", mail.length - 1);
var sp = mail.indexOf(" ", 0);
var pl = mail.indexOf("@.", 0);
for (i = 0; i < mail.length; i++) {
if (mail.charAt(i) == "/" || mail.charAt(i) == ":" || mail.charAt(i) == ";" || sp > 0 || pl > 0 ||
mail.charAt(i) == '"' || char1.length > 2 || y == -1 || y == 0 || e == 0 || w == mail.length - 1 || e == -1) {
return false;
}
}
}

For admins i just want to make sure their fields are not empty. For users i want to make sure their fields are not empty and their email field is valid. but when trying it, it's kinda only checks for the user fields. P.S: I apologize about not using codes, i didn't knew about this option. I want to detect the double-press of the space key. However, I want a single press of a space key to have a different function. The double-tap of space should only count if the taps of space are no more than, say, a half second apart. For example: The user hits space once, and javascript begins performing one action. 1/3rd of a second later, they hit the space bar again, and since that is within our threshold of 1/2 of a second, the action that began because the user hit the spacebar once should be cancelled, or undone (which I can write later) and the action when the user hits the spacebar twice should begin. Anyone have an idea how to do this? Thanks! Hi guys, I have written a double validation as below function validateDouble(ele){ // Custom trim funcation, i have written if(trim(ele.value) != ''){ var a = /^\d+(\.\d{0,2})?$/.test(trim(ele.value)); if(a){ return true; }else{ return false; } }else { ele.value = '0.00'; return true; } } I have copied from the net But this validation doesnt work when we enter the value as .65 (Means, it should accept this also, Please help me to change the regular expression) and in the same time when we enter this with out prefix, it should auto change to 0.65. Can some one help me to add in the above function. Hi, I have completed the necessary function and it does not need any changes however from the "alert" I need there has to be double quotes surrounding the search 'Lboro'. (I know I may be making a meal of the coding however the lecturer wants us to follow this due to everyone being at different levels of programming). I have used the '\' character however the double quotes do not end up in the position I require them?! My Coding function findAnyU (s){ var a = s , b , c , d , e = -1; for (var i = 0 ; i < pages.length && e == -1 ; i++){ b = pages[i].indexOf('['); c = pages[i].indexOf(']'); d = pages[i].substring(b+1, c).toLowerCase(); e = d.indexOf(s.toLowerCase()); } if(e >= 1) a += ' found' else a += ' not found' return (a) } alert (findAnyU('Lboro' , pages)); Current Alert = Lboro found Cheers George hi I wonder if someone out there can help me. I am very new to javascript and i have manged to understand a little of a double combo box with description however I would now like to be able to not only change the comment underneth but also add an image. This image (along with the comment) changes everytime the dropdownbox changes. I just cant seem to add the image. Please can anyone help I would really appreciate it and be extremely grateful. gr T hello I have a listbox full of names on a PHP website and was wondering if there was a way to grab the value during a double click to bring me to another form to display the name and information? I currently have a Drop-Down menu, which has headers you click on to show the links. This menu only allows one drop to be expanded at a time, and can be viewed here. I would like the headers to be able to have 'sub-headers' inside, which also drop-down,to reveal the links. I want them to have a different header colour, and to have the same rule where only one can be open at a time. while keeping the rule with the main headers. I have previously posted asking this, and got no reply, so I would really greatly appreciate any help and/support! Best Regards, Tim (P.S. I am still only learning JavaScript, and to make the current menu I have, took loads of help for a different project) Hi Can you please advise on this. When writing javascript what is best practice.... single or double quotes? I tried to research this and everyone contracdicts each other? thanks A I've been working with this script Code: function changeImage(layer_id, item_id, position) {
var theDiv = document.getElementById(layer_id);
var theImg = (theDiv != null) ? theDiv.firstChild : null;
if (theImg != null) {
// If the item id is 0, then just make the image empty lol
if (item_id == 0)
{
theDiv.parentNode.removeChild(theDiv)
} else {
theImg.setAttribute('src', 'images/' + layer_id + '-' + item_id + '.png');
}
} else {
var toAppend = '<div id="' + layer_id + '" style="position: absolute; z-index: ' + position + ';"><img src="images/' + layer_id + '-' + item_id + '.png" /></div>';
document.getElementById("item-images").innerHTML += toAppend;
}
}
where layer_id, item_id, and position are all defined elsewhere. I've been trying to get the images to append, and then run this line Code: theDiv.parentNode.removeChild(theDiv) when you click on them consecutively(click to append, click again to remove, so three consecutive clicks would have the image shown and four would not), but all I've succeeded at so far is breaking the script's functionality. Help? I have the double combo script working on another website for an auto parts dealer with only 1 make so the options are Choose Model and then Choose Years for that model, i.e., 1979-1987 for one model and 1988-1994 for option 2 of the same model, and similar options for the other models. The links go to the cart for that Model/Year and everything works fine. This time I'm trying to set up the same script where this auto parts dealer has 21 Makes with a span of years for each make: 2011 to 1969, i.e., about 40 years for every Make. This parts dealer wants the years listed first and then the makes and from there I'll link to the cart for the model. I have the code set up (with only 4 years set up for the first Make as a test, which is VW/Audi) just so I can get it working, however after picking the year it's not letting me pick a make. It appears to choose one randomly with no other options. I have posted the code below minus most of the makes and years to save space I have three questions: 1. Is this the right script for this search pattern? 2. Is there a way to fix this so I don't have to list 40 years for every make?this would cause massive code bloat. 3. Is there an error in my code? PS. I'm not a Javascript programmer but do understand some of what it is doing. <form name="doublecombo"> <select name="example" size="1" onChange="redirect(this.options.selectedIndex)"> <option value="">Choose Year</option> <option>2011</option> <option>2010</option> <option>2009</option> <option>2008</option> <option>2007</option> <option>2006</option> <option>2005</option> <option>2004</option> </select><br> <select name="stage2" size="1"> <option value="">Choose Make</option> </select> <input type="button" name="test" value="Go!" onClick="go()"> <script> <!-- /* Double Combo Script Credit By JavaScript Kit (www.javascriptkit.com) Over 200+ free JavaScripts here! */ var groups=document.doublecombo.example.options.length var group=new Array(groups) for (i=0; i<groups; i++) group[i]=new Array() group[0][0]=new Option("VW/Audi 2011","http://www.....") group[0][1]=new Option("VW/Audi 2010","http://www.....") group[0][2]=new Option("VW/Audi 2009","http://www.....") group[0][3]=new Option("VW/Audi 2008","http://www.....") group[1][0]=new Option("Acura","http://www.....") group[2][0]=new Option("BMW","http://www.....") group[3][0]=new Option("Geo","http://www.....") group[4][0]=new Option("Honda","http://www.....") group[5][0]=new Option("Hyundai","http://www.....") var temp=document.doublecombo.stage2 function redirect(x){ for (m=temp.options.length-1;m>0;m--) temp.options[m]=null for (i=0;i<group[x].length;i++){ temp.options[i]=new Option(group[x][i].text,group[x][i].value) } temp.options[0].selected=true } function go(){ location=temp.options[temp.selectedIndex].value } //--> </script> </form> Hi, I'm Sam and I'm new to this forum. I have a few question about double combo box. Before I get down on details I have to confess that my knowledge about javascript is almost zer0 so if you're posting any answer please elaborate. I've found this code somewhere online and I'd like to make some changes to this code. I've searched everywhere but couldn't find any answer yet. As you can see in this code, the javascript function can open a page in iframe once the user clicks on "Go". I'd like to know how to add links to the options in the first box so that it can open an iframe by itself, plus loads the next box , so when the user selects an option from the first box, the first box opens a page in iframe then loads the options for the second box. There should be two iframes side by side, the first iframe to open a page for the first box once the user selects the options in the box and the second ifram opens a page for second box once the user clicks on the "go". I just don't know how to add links to the options in the first box. Here's the code: Code: <html>

<body>
<form name="doublecombo">

I am working on my personal portfolio site, and am using a code that will make each portfolio piece appear in a new div when the name of the piece is clicked on. The problem is, JS does not seem to recognize double digits. I am not familiar with JS at all, I just got comfortable with CSS/HTML a few weeks ago! I am in over my head. It would really, really help if someone could show me how to change the code so that I could make about 15 to 20 divs instead of 9. Here is the code: Code: <script language="JavaScript">
numdivs=9
IE5=NN4=NN6=false
if(document.all)IE5=true
else if(document.layers)NN4=true
else if(document.getElementById)NN6=true
function init() {
showDiv(0)
}
function showDiv( which ) {
for(i=0;i<numdivs;i++) {
if(NN4) eval("document.div"+i+".visibility='hidden'")
if(IE5) eval("document.all.div"+i+".style.visibility='hidden'")
if(NN6) eval("document.getElementById('div"+i+"').style.visibility='hidden'")
}
if(NN4) eval("document.div"+which+".visibility='visible'")
if(IE5) eval("document.all.div"+which+".style.visibility='visible'")
if(NN6) eval("document.getElementById('div"+which+"').style.visibility='visible'")
}
</script>
Thank you for taking the time to read this! Hopefully someone can help. I'm finishing up an e-commerce website, and I can't quite figure out why the shopping cart feature is acting all screwy in Internet Explorer. It works fine in Firefox, but in IE, when you add a product to the cart it doesn't display the little pop-up notification, and when you click on the "my cart" at the top right the product quantities are incorrect about 70% of the time. For some reason IE keeps doubling the quantities; I think one of the scripts may be double refreshing the page I just can't figure out where. If anyone has any suggestions they would be much appreciated. The site I'm referring to is he www.tcatvs.com Thanks y'all! Also I'm using the jquery framework for much of the site. This is driving me nuts I need to replace all instances of "zz" with 'Z'. I can easily replace other strings such as a = a.replace(/mickeymouse/, "Z"); but a = a.replace(/zz/, "Z"); doesn't work. Must be a double characer thing? Hello, I'm trying to achieve what seems pretty simple, I have achieved both aspects successfully by themselves but together I have not I am trying to submit a form data via post, then I'm also trying to redirect I have got the window.location working I have the database writing working however I can't seem to get them to work sequentially I think the reason is that the post action redirects to itself, then the initial setinterval request is gone I try to do the sequential action this way Code: <a href=# onclick="document.forms['frm'].submit();redirect();">Submit</a> So, either the data posts and I'm stuck at the same page, or it redirects and the data doesn't post What am I missing? I read that to have multiple functions by one click, you separate them with a semi-colon as I have done I think as I mentioned that the key is the post to PHP_SELF which "nullifies" the redirect request eg. it never existed So what do I do? Also I'm not after the time interval, I was just trying to find a way for a user to be notified "Hey you're going to be redirected" by an alert (which I had this pop up working as well) then when they press okay, they are redirected. Ideally the user enters data, data is stored, pop-up, hit okay, redirect Thanks for any help I've got this bit of code that I've wrote and it was working absolutely fine like this: Code: function validatepostcode() {
var postcodevalue = document.getElementById("postcode").value;
if (postcodevalue.indexOf("S") == -1)
{
alert(postcodevalue + " is not a valid postcode.");
}
}
Until I tried to add double quotes: Code: function validatepostcode() {
var postcodevalue = document.getElementById("postcode").value;
if (postcodevalue.indexOf("S") == -1)
{
alert( \" postcodevalue \" + " is not a valid postcode.");
}
}
What I want to do is wrap the value of "postcodevalue" in double quotes, and since it's inside an alert, I used the escape sequence \", which is how it should be done as far as I know. But for some reason, Dreamweaver's giving me a syntax error warning and the code doesn't work. Am I using the double quotes wrong? Regards, Hashim. Hello, I am a hobbyist coder making a basic website for a friend, and I have a small problem. On an image slideshow, there is a counter at the bottom showing what image it is up to (ie 7/15), I'm not entirely sure how to change this into double digits (ie 07/15) I've found this thread (http://www.codingforums.com/showthread.php?t=212321) but am unsure how to integrate it into the slideshow I'm using, which is a different one. Here is the part from my JS I think that needs modifying: Code:
if (setting.displaymode.type=="manual" &&
!setting.displaymode.wraparound){
this.paginatecontrol()
}
if (setting.$status) //if status container defined
setting.$status.html(setting.curimage+1 + " / " + totalimages)
Is this the right bit of code? If more of the code is needed to solve this please let me know. Any help is greatly appreciated!
