I keep getting the above error an uncaught type error saying something isn't a function when I think it is. I'll post the code and point out where I am referencing the elements. I'm making a Todo list which generates a todo item, a checkbox, and a remove icon. When users click the checkbox, I want it to apply the text-decoration: line-through to the Todo item. I added an onclick="boxChecked"() to the input with the checkbox and referenced right away in my function. It keeps saying in my HTML that it isn't defined. Is this because it is all JavaScript being referenced to the HTML doc externally? Maybe I have the function in the wrong spot?
Here is the Console Log
function show() {
var todos = get_todos();
var html = "<ul>";
for (var i = 0; i < todos.length; i++) {
html +=
'<li class="todo-item">' +
'<span class="todo-label">' +
todos[i] +
"</span>" +
/*Here is the onclick--->*/ '<input onclick="boxChecked()" class="checkBox" type="checkbox">' +
'<button class="remove" id="' +
i +
'">' +
'<i class="fa fa-trash" aria-hidden="true"></i>' +
"</button>" +
"</li>";
}
html += "</ul>";
document.getElementById("todos").innerHTML = html;
var buttons = document.getElementsByClassName("remove");
for (var i = 0; i < buttons.length; i++) {
buttons[i].addEventListener("click", remove);
}
/*Here is the function for it---->*/ function boxChecked() {
var x = document.getElementByClassName("todo-item");
if (x.style.textDecoration === "none") {
x.style.textDecoration = "line-through";
} else {
x.style.textDecoration = "none";
}
}
}
document.getElementById("add").addEventListener("click", add);
show();
Below is an image from w3schools where I tried it all on one page (without referencing it through an external JavaScript file) and it works. I'm really not sure. Any help would be greatly appreciated!

I'm coding a wordpress theme and I want to increment a load more button.
I'm not using wordpress always and this is the first time I've this problem with a javascript variable. The variable pull_page in fact will not increment and every time the script will run it will fetch only two pages. Is there any error in the code, and how I can fix it?
$('#load-more').on('click', function(e){
e.preventDefault();
var pull_page = 1;
var jsonFlag = true;
if(jsonFlag){
pull_page++;
$.getJSON("/beta/wp-json/portfolio/all-posts?page=" + pull_page, function(data){
if(data.length){
$.each(data, function(i, item){
var html = '<div class="card">';
html += '<a href="'+ item.permalink +'">';
html += '<img class="card-img-top w-100" src="'+ item.featured_img_src +'" id="case-studies" />';
html += '<div class="overlay"><h4 class="text-center" id="client-name">'+ item.title +'</h4></div>';
html += '</a>';
html += '</div>';
$('body').find('.card-columns')
.append(html);
});
}
else{
jsonFlag = false;
}
}).done(function(data){
if(data.length >= 4){
jsonFlag = true;
}
else{
jsonFlag = false;
}
});
}
}); // end load more
You're resetting pull_page to 1 each and every time the load more button is clicked.
Move it outside.
var pull_page = 1;
$('#load-more').on('click', function(e) {
...
I am trying to call the delete button to remove the listed file. Can anyone help me to build the logic.
$(document).ready(function () {
$('input[type = "file"]').change(function (e) {
var input = document.getElementById('fileUploader');
var output = document.getElementById('divFiles');
var HTML = "<table>";
for (var i = 0; i < input.files.length; ++i) {
HTML += "<tr><td>" + input.files.item(i).name + "</td><td> <button ></button></td></tr>";
}
HTML += "</table>";
output.innerHTML = HTML;
});
});
You can remove the parent tr tag containing button delete like
$('.btnDelete').on('click', function () {
$(this).closest('tr').remove();
});
Stumped on another one. I'm using boostrapJS to create a Nav-List. Ideally the headers will remain collapsed by default, but will expand when clicked. Right now I have some javascript that will go and dynamically populate the List, but the click event seems to be doing nothing. (sort of - I click on the header and it jitters a bit, but it does not collapse).
I've looked at the code examples, and I'm pretty sure I'm using the same classes and div structure, but It still seems to be not working, and it's not throwing any errors.
Here is my Code:
$('#header').append('<ul class="nav nav-list">');
for (i = 0; i < len; i++) {
k = keys[i];
$('#header').append('<label class="tree-toggle nav-header">' + keys[i] + '</label>');
for (var j in groupedtemplates[k]) {
$('#header').append('<li data-value=' + groupedtemplates[k][j].id + '>' + groupedtemplates[k][j].attributes.im_name.value + '</li>');
}
}
$('#header').append('</ul>');
$(document).ready(function () {
$('.tree-toggle').click(function () {
$(this).parent().children('ul.tree').toggle(200);
});
});
The HTML that it's being inserted into is just a simple container.
<div class="well" style="width:100%; padding: 8px 0;" id="header">
</div>
Figured it out.
When you append a tag without a closing tag, the browser inserts one for you. Because of this the objects were not appearing as children.
This is my revised solution that puts all the data to be appended in a variable, then appends it afterwards.
for (i = 0; i < len; i++) {
k = keys[i];
var toAppend = "";
toAppend = toAppend + '<ul class="nav nav-list">' + '<li><label class="tree-toggle nav-header">' + keys[i] + '</label</li>' + '<ul class="nav nav-list tree">'
for (var j in groupedtemplates[k]) {
toAppend = toAppend + '<li data-value=' + groupedtemplates[k][j].id + '>' + groupedtemplates[k][j].attributes.im_name.value + '</li>'
}
toAppend = toAppend + "</ul></ul>";
$('#header').append(toAppend);
}
I need to ask for help.
Having this code:
$(".apprezzamenti").click(function()
{
var id = $(this).attr('id');
$.get("http://localhost/laravel/public/index.php/apprezzamenti_modal/"+id,
function(data)
{
data_parsed = JSON.parse(data);
// BELOW is the loop that I would like to generate multiple div using .append()
for(var i=0; i<data_parsed.length; i++)
{
var html = '<img src="images/provvisorie/immagine-profilo.png" width="30px" and height="30x" />';
html += ' ';
html += "<a href='http://localhost/laravel/public/index.php/utente/" + data_parsed[i].id_user + "' style='font-weight: bold;'>" + data_parsed[i].username + "</a>";
$(".modal-body-apprezzamenti>p").append(html).append('.modal-body-apprezzamenti>p').append($('<br/>'));
}
$(".chiudi-popup").click(function()
{
$(".modal-body-apprezzamenti>p").html('');
});
$('#main').click(function()
{
$(".modal-body-apprezzamenti>p").html('');
});
});
});
I'd like to create a div for each looping.
How could I do? Thanks for your help.
With jQuery it's very easy, look at this JSFiddle
http://jsfiddle.net/Ldh9beLn/
I use the function jQuery appendTo() to insert each div inside another div with id = "inserts" if you don't understand a section of this code or how to adapt to yours leave me a comment.
var things = ["apple", "house", "cloud"];
for (var i = 0; i < things.length; i++) {
$("<div>"+things[i]+"</div>").appendTo("#inserts");
}
Can you please tell me how to make list in jQuery mobile? I am trying to make this type list as given in fiddle on pop up screen dynamically .
Here is the fiddle
In this fiddle I make two rows.In first row there is only p tag. But in second row there is nested collapsible rows. I need to make same thing in pop up screen. I am able to make first row. But In my second row contend is null why? Can you suggest where I am wrong?
fiddle
$(function () {
$('#test').click(function(){
alert('d');
createCommandPopUpTabs();
$("#tabbedPopup").popup("open");
});
});
var tabsHeader = [ "InputParameter", "basic"];
var tabsHeader_basic = [ "XYZ", "Third Level",
];
function createCommandPopUpTabs(){
var header = "<h3 >dd</h3>";
var commmand = 'dd';
var button = '<button onclick="return submitCommand("'+
'")" style="" class="donebtn common-button1">Save</button>';
$("#commandInfo").append(button);
$("#commandInfoheader").html(header);
for ( var i = 0; i < tabsHeader.length; i++) {
var headerId = tabsHeader[i] + "_tab" + commmand;
var header = "<div data-role='collapsible' data-collapsed='false' id='"
+ headerId + "'><h3>InputParameter</h3></div>";
var content ;
if(tabsHeader[i]=="InputParameter"){
content = "<p>yes</p>";
}else if(tabsHeader[i]=="basic"){
for ( var i = 0; i < tabsHeader_basic.length; i++) {
headerId = tabsHeader_basic[i] + "_tab" + commmand;
header = "<div data-role='collapsible' data-collapsed='false' id='"
+ headerId + "'><h3>basic</h3></div>";
content += getcontend(tabsHeader_basic[i]);
}
}
$("#tabbedSet").append(header);
$("#tabbedSet").find("#" + headerId).append(content);
$("#tabbedSet").collapsibleset("refresh");
}
}
function getcontend(name){
if(name=="Third Level"){
return"<p>Third Level></p>";
} if(name=="XYZ"){
return"<p> second Level></p>";
}
}
There are errors in your code and logic. I will only go over a couple of them to hopefully get you on the right path:
In tabsHeader_basic array the Third Level has a space in it which you later use as an ID which makes it an invalid ID because you cannot have spaces in an ID.
From the HTML 5 Draft:
The value must not contain any space characters.
Also, the "basic" collapsible div needs to exist before you start adding the nested collapsible div.
So this line needs to come out of the for loop
header = "<div data-role='collapsible' data-collapsed='false' id='"+ headerId + "'><h3>basic</h3></div>";
Go through the JSFiddle and compare your code agaisnt my changes.
Hopefully that helps! Let me know if you have any other questions.
I have updated createCommandPopUpTabs() function.
Also removed space in Third Level on var tabsHeader_basic = ["XYZ", "ThirdLevel"];
Check the Updated Fiddle
function createCommandPopUpTabs() {
var header = "<h3 >dd</h3>";
var commmand = 'dd';
var button = '<button onclick="return submitCommand("' +
'")" style="" class="donebtn common-button1">Save</button>';
$("#commandInfo").html(button);
$("#commandInfoheader").html(header);
$("#tabbedSet").html('');
for (var i = 0; i < tabsHeader.length; i++) {
var headerId = tabsHeader[i] + "_tab" + commmand;
var header = "<div data-role='collapsible' data-collapsed='true' id='" + headerId + "'><h3>" + tabsHeader[i] + "</h3></div>";
$("#tabbedSet").append(header);
var content;
if (tabsHeader[i] == "InputParameter") {
content = "<p>yes</p>";
$("#tabbedSet").find("#" + headerId).append(content);
} else if (tabsHeader[i] == "basic") {
for (var j = 0; j < tabsHeader_basic.length; j++) {
var headerId1 = tabsHeader_basic[j] + "_tab" + commmand;
var header1 = "<div data-role='collapsible' data-collapsed='true' id='" + headerId1 + "'><h3>" + tabsHeader_basic[j] + "</h3></div>";
var content1 = getcontend(tabsHeader_basic[j]);
$("#tabbedSet").find("#" + headerId).append(header1);
$("#tabbedSet").find("#" + headerId1).append(content1);
}
}
$("#tabbedSet").collapsibleset("refresh");
}
}
