I've gut a simple function in my page for hiding/showing panes when some tabs are clicked. Simplest thing in the world, right?
Works perfectly in Firefox and Chrome, but in IE it only half works. It will hide all the sopMonthContainers, but fails to find the container with a matching ID and display it.
$('.sopTab').click(function(e){
if ($(this).hasClass("activeTab") === false){
$(".sopTab").removeClass("activeTab");
$(this).addClass("activeTab");
};
var selectionID = $(this).attr("id");
$(".sopMonthContainer").css("display", "none");
$(".sopMonthContainer#the"+selectionID).css("display", "block");
});
I'm hoping it isn't some stupid typo that I've overlooked, but I've been staring at this thing for nearly an hour trying different variations on the theme. I've tried reworking the selector IDs to make sure they're unique (hence the "the" in the selector on the last line), I've tried selecting using only ID, I've tried using different methods to hide/show... same result no matter what.
EDIT: the relevant markup. It's got some coldfusion elements, anything between ##'s is a coldfusion variable.
<div class="sopTab" id="sopContainer#DateFormat(pubdate,'mmmm')#" style="">
#DateFormat(pubdate,"mmmm")#: <span id="sum#DateFormat(pubdate,"mmmm")#">0</span>
</div>
<cfoutput query="GetProductBasicInfo">
<div class="sopMonthContainer" style="display:none;"
id="theSopContainer#DateFormat(pubdate,'mmmm')#">
[div content goes here]
</div>
</cfoutput>
Note for example this:
<div class="sopTab" id="sopContainerNovember" style="">November: <span id="sumNovember">0</span></div>
<div class="sopMonthContainer" style="display:none;" id="theSopContainerNovember">
when you click on sopTab, the selector you build is
#thesopContainerNovember
// ^
but the ID of the target is
#theSopContainerNovember
// ^
the IDs did not match(it's the uppercase and lowercase s )
I think that the last line should be
$(".sopMonthContainer #the"+selectionID).css("display", "block");
There should be a space here. But I might be wrong. It would help if you would post a link to a jsFiddle or working example.
You have an error in your page. I noticed there's some code that looks like someone has attemped to comment it out but done it incorrectly.
In your sopQuery.cfm file, change the code here:
<script language="javascript">
<!--
cfform_submit_status["productSelections"]=null;
function check_TF_productSelections( theForm ){
cfform_isvalid = true;
cfform_error_message = "";
cfform_invalid_fields = new Object();
if ( cfform_isvalid ){
return true;
}else{
alert( cfform_error_message );
return false;
}
}
//-->
</script>
To this:
<!--
<script language="javascript">
cfform_submit_status["productSelections"]=null;
function check_TF_productSelections( theForm ){
cfform_isvalid = true;
cfform_error_message = "";
cfform_invalid_fields = new Object();
if ( cfform_isvalid ){
return true;
}else{
alert( cfform_error_message );
return false;
}
}
</script>
-->
OR... If the code is supposed to be uncommented, change it to this, but note that the error will persist as the variable cfform_submit_status is not defined anywhere:
<script language="javascript">
cfform_submit_status["productSelections"]=null;
function check_TF_productSelections( theForm ){
cfform_isvalid = true;
cfform_error_message = "";
cfform_invalid_fields = new Object();
if ( cfform_isvalid ){
return true;
}else{
alert( cfform_error_message );
return false;
}
}
</script>
Presumably it's supposed to be defined here:
<script type="text/javascript" src="/bluedragon/scripts/cfform.js"></script>
But I looked and that file is empty.

i'm trying to work the following code of script. but its not working. i don't know what is the problem. the x variable i created contains nothing. but still the if condition is not working. i have tried printing the x variable in an alert box and it prints nothing, which means that it contains nothing. But in its not picking up the condition don't know why. And there are no console errors.
<div id="test">
</div>
<script>
var x = document.getElementById("test").innerHTML;
if(x == '') {
document.getElementById("test").innerHTML = 'There are No friends posts yet my love!!';
}
</script>
Your variable x contains not empty string but some spaces. Try to use trim() function to remove these symbols:
if(x.trim() == ''){
...
}
This will work!
<script>
var x=document.getElementById("test").innerHTML;
if(x.trim() == ''){
document.getElementById("test").innerHTML='There are No friends posts yet my love!!';
}
</script>
use innerText
if(x.innerText === ''){
https://jsfiddle.net/s4aLcfm5/
The issue is that your 'x' variable is not empty. It contains two return characters. Try removing all the white-space between your open and close div statement. Here is the corrected code:
<div id="test"></div>
<script>
var x=document.getElementById("test").innerHTML;
debugger;
if(x == ''){
document.getElementById("test").innerHTML='There are No friends posts yet my love!!';
}
</script>`
Simply add or remove returns within the div statement to see this work or not work.
Your code works. It all comes down to the way that your html is written:
<div id="test">
// This is an unnecessary space that's what is making your condition fail
</div>
<script>
var x=document.getElementById("test").innerHTML;
if(x == ''){
document.getElementById("test").innerHTML='There are No friends posts yet my
love!!';
}
</script>
Clean up your html: <div id="test"></div>
And you don't need anything else
I wanted an if statement to show an image or html code depending on the webpage. I got this far and the html table doesn't appear at all (appears blank):
<script type="text/javascript">
<!--
var url = document.location.pathname;
if( document.location.pathname == '/tagged/photos' ){
document.innerHTML('<table><tr> hello </tr> </table>');
}
if( document.location.pathname == '/tagged/news' ){
document.write("<b>This is my news page</b>");
}
//-->
</script>
I'd do it slightly differently
Add both markup to the page, and show/hide as approproate:
<table id="table"><tr> hello </tr></table>
<span id="title"><b>This is my news page</b></span>
<script type="text/javascript">
$(function(){
var url = document.location.pathname;
if( url == '/tagged/photos' ){
$('#title').hide();
$('#table').show();
}
if( url == '/tagged/news' )
{
$('#title').show();
$('#table').hide();
}
})
</script>
I have assumed you have JQuery since it is tagged
You're using document.innerHTML, which doesn't exist. At the very least, you need to get a proper element:
document.documentElement.innerHTML = 'some HTML';
Setting aside everything else that's wrong with this approach, I'm not sure, why would you use document.write() in one branch and someElement.innerHTML in the other.
I'd suggest the following approach:
function pagePopulate() {
// you're looking at the pathname, use a sensible (meaningful) variable-name:
var pagePath = document.location.pathname,
// this is a map, of the relationship between page and content:
pathToContent = {
// pagename : html
'photos': '<table><tbody><tr><td>photos page</td></tr></tbody></table>',
'news': '<b>This is the news page</b>'
},
// getting a reference to the <body> element:
body = document.querySelector('body');
// setting the innerHTML of the <body>,
// if pagePath = 'tagged/photos', splitting with '/' would return:
// ['tagged','photos'], calling 'pop()' returns the last element of the array
// 'photos', which returns that string to the square brackets, resulting in:
// pathToContent['photos'], which would yield the '<table>...</table>' HTML.
// if that call resulted in an undefined, or falsey, value, then the default
// (the string *after* the '||' would be used instead:
body.innerHTML = pathToContent[pagePath.split('/').pop()] || '<h2>Something went wrong</h2><img src="http://blog.stackoverflow.com/wp-content/uploads/error-lolcat-problemz.jpg" />';
}
// calling the function:
pagePopulate();
References:
|| (logical 'or' operator).
Array.prototype.pop().
document.querySelector().
String.prototype.split().
I know this is a silly question but i am not able to get the required result.I want to assign a javascript variable bck in document.getElementById(bck) .Everything is working fine i.e. alert displaying the correct value of variable bck but when i am using it inside the document.getElementbyID i am getting the following error:
document.getElementById(bck) is null
I googled it and looked in SO relevant topics also but got nothing helpful.
the value of backdropcontent[m][1] is Reden,also the value of selectedbg is Reden.
<script>
for ( var m=0;m<backdropcontent.length;m++) {
if(selectedbg==backdropcontent[m][1]){
var bck=backdropcontent[m][1]+'div1';
alert(bck);
document.getElementById(bck).style.display = "block";
document.getElementById(bck).style.top = "0px";
}
}
</script>
html part:
<div class="mcdropdown" id="Redendiv1" style="display:none;position:relative">
<a style="cursor: default !important">
<input type="text" name="reden1" id="reden1" style="background-image: url('<?php echo $mosConfig_live_site; ?>/templates/performitor/images/123.png');background-repeat: no-repeat;height:14px;width:130px !important;color:#BDBDBD;border: 1px solid #8e9daa;" disabled="disabled" value="Totaal" autocomplete="off"/>
</a>
</div>
please note that i dont want to alter the structure of my code so please dont suggest any major change.
Any help will be appreciated.Thanks.
The element with id backdropcontent[m][1]+'div1', does not exist
It's throwing error mostly because your element doesn't exist on the page yet. Move your <script> block below your code or use window.onload event.
window.onload = function(){
//your code
}
Or using jquery:
$(document).ready(function() {
// your code
});
you use the code in the following pattern
<script>
for ( var m=0;m<backdropcontent.length;m++) {
if(selectedbg==backdropcontent[m][1]){
var bck=backdropcontent[m][1]+'div1';
alert(bck);
document.getElementById("bck");.style.display = "block";
document.getElementById(bck).style.top = "0px";
}
}
</script>
May be this code helps you.
So I am having a problem with HTML5 and javascript.
I made a few .js files for the javascript part and I made the link to connect it with the HMTL code but it will not show the javascript part.
This is my HTML
<!doctype html>
<html lang="en">
<head>
<title>Gateway Tunes</title>
<meta charset="utf-8" />
<script src="playlist_store.js"></script>
<script src="playlist.js"></script>
</head>
<body>
<form>
<input type="text" id="songTextInput" size="40" placeholder="Song name">
<input type="button" id="addButton" value="Add Song">
</form>
<ul id="playlist">
</ul>
</body>
</html>
and here are my javascript files; the names of the files are at the top
playlist_store.js
function save(item) {
var playlistArray = getStoreArray("playlist");
playlistArray.push(item);
localStorage.setItem("playlist", JSON.stringify (playlistArray));
}
function loadPlaylist() {
var playlistArray = getSavedSongs();
var ul = document.getElementById('playlist");
if (playlistArray !Null) {
for (var i = 0; i < playlistArray.length; i++) {
li.innerHTML = playlistArrray[i];
ul.appenChild(li);
}
}
}
function getSavedSongs() {
return getStoreArray("playlist")
}
function getStoreArray (key);
var playlistArray = localStorage.getItem(key);
if(playlistArray == null || playlistArray == "") {
playlistArray = new Array();
}
else {
playlistArray = JSON.parse (playlistArray);
}
return playlistArray;
}
playlist.js
window.onload = init;
function init() {
var button = document.getElementById ("addButton");
button.onclick = handleButtonClick;
loadPlaylist();
}
function handleButtonClick () {
var textInput = document.getElementById("songTextInput");
var songName = textInput.value;
if (songName == "") {
alert("Button was clicked!");
}
else {
alert("Your track has been added!");
}
var li = document.createElement("li");
li.innerHTML = songName;
var ul = document.getElementById("playlist");
ul.appendChild(li);
save (songName);
}
You've got some syntax errors so your javascript isn't running.
In playlist_store.js
var ul = document.getElementById('playlist");
Opens a string with ' but tries to close it with ". It doesn't matter which you use as long as you're consistent, so you can either change it to 'playlist' or "playlist".
if (playlistArray !Null) {
If you're trying to make sure playlistArray isn't null you can do
if (playlistArray != null) {
notice != as the comparison and null needs to be lowercase. If you want to make sure it isn't just undefined or null you can simply do if (!playlistArray).
ul.appenChild(li); needs to be ul.appendChild(li);.
I'm sure there's more, check over your code.
The first line of your script (and the only one that isn't just a function definition) is window.onload = init;. This means that after the page has loaded, your init function is called.
This function looks up the element with id addbutton, and then calls a method on the returned result. Since you don't have an element with this ID, there won't be any object returned, and so an exception will be thrown (something like "button is null or not an object", depending on your browser). This exception stops the method from executing further - and in particular, loadPlaylist() will not be called.
The moral of the story here though is pay attention to the JavaScript error console, especially while you're doing development! You browser will almost certainly have displayed a red exclamation mark icon or similar, which you could double-click to give you the name, message and location of the exception.
You really don't need to post your code listing on Stack Overflow to ask us what's wrong with it, when your browser is already capable of telling you exactly where the problem is.
I'm about 1 day old in using jquery, and is currently having a nightmare with it. I alreadt spent half of my day trying to get rid of this error.
I did some reading after “googling” the error (sorry, Bing!) and discovered that most of these errors result from the jquery file not being properly loaded. Okay…that started to point me in the right direction but I still couldn’t figure out why it wasn’t pathing properly. I mean, I was doing as people said – I would drag the .js file into my designer and it would print out the proper path, but still the error shows.
Here's my exact code in my editor template (with the error):
#model bool
#{
string status = "Active";
string buttonValue = "Deactivate";
string hiddenValue = "true";
if (!ViewData.Model)
{
status = "Inactive";
buttonValue = "Activate";
hiddenValue = "false";
}
}
<div style="width:100px; float:left;">
<img id = "AD_Img" src = "/Content/themes/base/images/icon_#(status).png" alt = #(status) />
<label for = "AD_Img" id = "AD_Label" >#(status)</label>
</div>
<div style="width:100px; float:left;">
<input type="button" id = "AD_Button" value = #(buttonValue) style = "width:100px" onclick = "ChangeStatus()" />
<input id = "AcntStatus" type = "hidden" name = "AcntStatus" value = #(hiddenValue) />
</div>
and in the same cshtml file, the script goes this way:
<script type="text/javascript" src="/Scripts/jquery-1.5.1.min.js">
function ChangeStatus()
{
var ButtonVal = $("#AD_Button").val();
alert(ButtonVal);
if (ButtonVal == "Deactivate")
{
var stat = "Inactive";
var buttonVal = "Activate";
var HiddenValue = "false";
}
else if (ButtonVal == "Activate")
{
stat = "Active";
buttonVal = "Deactivate";
HiddenValue = "true";
}
$("#AD_Img").attr({src: "/Content/themes/base/images/icon_"+stat+".png", alt: stat});
$("#AD_Label").html(stat);
$("#AD_Button").val(buttonVal);
$("#AcntStatus").val(HiddenValue);
}
</script>
The debugger stops on the ChangeStatus function of the input element on the following line:
<input type="button" id = "AD_Button" value = #(buttonValue) style = "width:100px" onclick = "ChangeStatus()" />
i tried to debug it by using this in my function code:
function ChangeStatus()
{
var ButtonVal = document.getElementById("AD_Button").value;
alert(ButtonVal);
}
And it works properly, it returns the exact string that I'm looking for without that error, but why? What's wrong with my codes?
Please help me figure this out.
This:
$("#AD_Img").attr(src: "../../../Content/themes/base/images/icon_"+stat+".png", alt: stat);
forces an Syntax-error. It has to be:
$("#AD_Img").attr({src: "../../../Content/themes/base/images/icon_"+stat+".png", alt: stat});
Edit:
Also take a look at your <script>, you can't mix external JS and internal JS.
This:
<script type="text/javascript" src="../../../Scripts/jquery-1.5.1.min.js">
//your code
</script>
Has to be splitted into
<script type="text/javascript" src="../../../Scripts/jquery-1.5.1.min.js"></script>
<script type="text/javascript">
//your code
</script>
