I'm trying to add a function to my website so when the user clicks on a footnote the browser will display it inline. Here is how far I have gotten,
var locate= document.getElementById("footnote1");
var note= document.getElementById("footnotes2");
function footnote() {
locate.onclick= note.style.display="inline";
};
any help would really be appreciated.
Here is an example of what you want.
var locate = document.getElementById("footnote1");
var note = document.getElementById("footnotes2");
locate.onclick = function() {
note.style.display = "inline";
};
Working Example
http://jsfiddle.net/v8fHE/
you just had to wrap the onclick action in a function
trigger.onclick=function(){toChange.style.background="#FF0000"};

I got the basics of my javascript to function with help I got here on Stackoverflow. I see a bit of room for improvement on what I have now though. A lack of Javascript knowledge keeps me stuck unfortunately.
I'm trying to set arguments such as width, height, toolbar, status for a popup window in a variable. I tried every way I could find both here and via Google to get the syntax right but whatever I try it doesn't seem to work.
See below in Function1 what I ended up with (Function2 still has the hardcoded parameters that I'm trying to put in the variable called windowSpecs).
var windowSpecs = "\'toolbar=no,status=no,scrollbars=yes,resizable=yes,top=500,left=500,width=600,height=745\'";
var function1Name = "test_function_1";
var function1Url = "https://www.google.com";
var function1Class = ".test_function_class1";
var function2Name = "test_function_2";
var function2Url = "https://www.cnn.com";
var function2Class = ".test_function_class2";
// Function 1
window[function1Name] = function () {
window.open(function1Url, windowSpecs,"_blank",);
}
jQuery(function1Class).click(function() {
window[function1Name]();
});
// Function 2
window[function2Name] = function () {
window.open(function2Url, "_blank", "toolbar=no,status=no,scrollbars=yes,resizable=yes,top=500,left=500,width=600,height=745");
}
jQuery(function2Class).click(function() {
window[function2Name]();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Any pointers that could help me figure this out would be greatly appreciated!
I'm new to javascript & i want to do this simple thing.
I want to make a script which goes to coded url's & clicks on a button each time the script is executed.
Suppose,i have these links -
I want the javascript to to go on these links after running it & trigger another small js for both links after they are fully loaded.
Here's what i tried
var linkArray = ('https://facebook.com/user1','https://facebook.com/user2');
for (var i = 0; i < linkArray.length; i++) { window.open({
url: linkArray[i]
});
}
linkArray.onload="blabla();"
function blabla()
{
var inputs = document.getElementsByClassName('_42ft _4jy0 _63_s _4jy4 _517h _51sy');for(var i=1; i<inputs.length;i++) {inputs[i].click();}
}
Can anyone please help?
Thanks in advance! :-)
Please change to this, this would works
var linkarray = ('https://facebook.com/user1', 'https://facebook.com/user2');
var linkArray = [https://facebook.com/user1,https://facebook.com/user2];
isn't valid, please set your array like this:
var linkArray = ['https://facebook.com/user1', 'https://facebook.com/user2'];
var malediv = document.querySelector('.male');
var femalediv = document.querySelector('.female');
var male_sources = [
"/images/m1.png",
"/images/m2.png",
"/images/m3.png",
"/images/m4.png",
"/images/m5.png",

]
var female_sources = [

"/images/f5.png",
"/images/f6.png",

]
function displayRandMaleImage() {
malediv.innerHTML = "";
var malerandom_number = Math.floor(Math.random() *
male_sources.length);
var random_male_image_source = male_sources[malerandom_number];
maleimg = document.createElement('img');
maleimg.setAttribute('src', random_male_image_source);
malediv.append(maleimg);
alert('maleimagedisplayed');
}
function displayRandFemaleImage() {
femalediv.innerHTML = "";
var femrandom_number = Math.floor(Math.random() * female_sources.length);
var random_female_image_source = female_sources[femrandom_number];
femaleimg = document.createElement('img');
femaleimg.setAttribute('src', random_female_image_source);
div.append(femaleimg);
}
function displayRandImages(){
displayRandMaleImage();
displayRandFemaleImage();
alert('SKEEET');
}
none of my display random image fundtions are working in my html page that this is embedded in. I even added a test function "anAlert" that works perfectly. Please help me to understand what i can do to make this work.
There are two reasons why it isn't working.
1) You haven't defined the button. Which should've been done like:
var button = document.querySelector('.button_class');
or using the id:
var button = document.getElementById('button_id');
2) Your function to call the other two display functions is named displayRandImages()
function displayRandImages(){
displayRandMaleImage();
displayRandFemaleImage();
alert('SKEEET');
}
whereas, you've used the function displayRandomImage() in your click event:
button.addEventListener('click', displayRandomImage);
displayRandImages() != displayRandomImage()
button is not defined
button.addEventListener('click', displayRandomImage);
You should use it like
document.getElementById('buttonid').addEventListener('click', displayRandImages);
where 'buttonid' is id of your button, should be defined in html.
One more thing, as you are accessing button outside any other js function, So it'll be called on page load.
So you have to write this javascript after your html code so that it'll be called after button element rendered in HTML.
Currently I hide and show the content of a div like this:
var header = null;
var content = null;
var mainHolder = null;
var expandCollapseBtn = null;
var heightValue = 0;
header = document.getElementById("header");
content = document.getElementById("content");
mainHolder = document.getElementById("mainHolder");
expandCollapseBtn = header.getElementsByTagName('img')[0];
heightValue = mainHolder.offsetHeight;
header.addEventListener('click', handleClick, false);
mainHolder.addEventListener('webkitTransitionEnd',transitionEndHandler,false);
function handleClick() {
if(expandCollapseBtn.src.search('collapse') !=-1)
{
mainHolder.style.height = "26px";
content.style.display = "none";
}
else
{
mainHolder.style.height = heightValue + "px";
}
}
function transitionEndHandler() {
if(expandCollapseBtn.src.search('collapse') !=-1)
{
expandCollapseBtn.src = "expand1.png";
}
else{
expandCollapseBtn.src = "collapse1.png";
content.style.display = "block";
}
}
This is fine if the content is static, but I'm trying to populate my div dynamically like so.
This is called from an iphone application and populates the div with a string.
var method;
function myFunc(str)
{
method = str;
alert(method);
document.getElementById('method').innerHTML = method;
}
I store the string globally in the variable method. The problem I am having is now when I try expand the div I have just collapsed there is nothing there. Is there some way that I could use the information stored in var to repopulate the div before expanding it again? I've tried inserting it like I do in the function but it doesn't work.
Does anyone have any ideas?
to replicate:
Here is the jsfiddle. jsfiddle.net/6a9B3 If you type in text between
here it will work fine. I'm not sure
how I can call myfunc with a string only once in this jsfiddle, but if
you can work out how to do that you will see it loads ok the first
time, but when you collapse the section and attempt to re open it, it
wont work.
If the only way to fix this is using jquery I dont mind going down that route.
is it working in other browsers?
can you jsfiddle.net for present functionality because it is hard to understand context of problem in such code-shoot...
there are tonns of suggestions :) but I have strong feeling that
document.getElementById('method')
returns wrong element or this element not placed inside mainHolder
update: after review sample in jsfiddle
feeling about wrong element was correct :) change 'method' to 'info'
document.getElementById('method') -> document.getElementById('info')
I think you want to use document.getElementById('content') instead of document.getElementById('method') in myFunc.
I really see nothing wrong with this code. However, a guess you could explore is altering the line
content.style.display = "none";
It might be the case that whatever is displaying your html ( a webview or the browser itself) might be wiping the content of the elemtns, as the display is set to none
just a quick one, im using a oop style for my javascript game but for some reason when i add in a new class it kills any functions from other classes i have included.
Here is the script i am talking about which is my main file which i will include all my class files in:
$(document).ready(function(){
var canvas = document.getElementById("TBG");
var context = canvas.getContext("2d");
var ui = new Gui();
// var level = new Level();
//----------Login/Register Gui --------------
$('#TBG').hide();
$('#load-new').hide();
$('#reg').hide();
$('#login').hide();
//if login_but is clicked do ui.login function
$('#login_but').click(ui.login);
//if reg_but is clicked do ui.register function
$('#reg_but').click(ui.register);
$('#new_but').click(function(){
game_settings("new");
});
$('#load_but').click(function(){
game_settings("load");
});
//if login_sumbit button is clicked do ui.login_ajax function
$("#login_submit").click(ui.login_ajax);
$("#reg_submit").click(ui.register_ajax);
$("#welcome").on("click", "#logout_but", ui.logout);
//___________________________________________________________________
//Initialisation of game
function game_settings(state){
if(state == "load"){
ui.load_game();
//do ajax call to load user last save
level.level_init(0,1);
}
else{
//set beginning params
//Change screens
ui.new_game();
alert("new game");
}
}
});
in the context of the script above, my problem is when i just have the call to new Gui() without the call to new level underneath or commented like you can see, well then all of the functions below under the heading login/register gui works perfectly, but as soon as i put the call to new level in or uncomment it, it kills all of the functions under the login/ register gui heading.
Why is this?
EDIT: here is the level.js file in case you would like to see it and how i am constructing my classes:
function Level(){
this.level_init = function(level, location){
var saved_level = level;
var saved_location = location;
};
this.get_tileset = function(){
};
this.draw = function() {
}
}
Thanks
Tom
