So, I'm new to javascript.
My code is the following, it is based on a xaml file with a canvas and a couple of borders in it:
var defaultPage = null;
var aantalKliks;
var correcteBorders;
var incorrecteBorders;
var geenAntwBorders;
function onLoaded() {
defaultPage = document.getElementById('DefaultPage');
alert('In onloaded van Default.xaml.');
aantalKliks = 0;
aantalBorderKliks = 0;
correcteBorders = new Array();
for (var i = 0; i < 3; i++) {
correcteBorders[i] = defaultPage.content.findName('CorrecteBorder' + i);
}
incorrecteBorders = new Array();
for (var i = 0; i < 3; i++) {
incorrecteBorders[i] = defaultPage.content.findName('IncorrecteBorder' + i);
}
geenAntwBorders = new Array();
for (var i = 0; i < 3; i++) {
geenAntwBorders[i] = defaultPage.content.findName('GeenAntwBorder' + i);
}
}
function OnCanvasClicked() {
if (aantalKliks == 2) {
aantalKliks = 0;
}
if (aantalKliks == 0) {
for (var i = 0; i < correcteBorders.length; i++) {
correcteBorders[i].Visibility = 'Visible';
}
for (var i = 0; i < incorrecteBorders.length; i++) {
incorrecteBorders[i].Visibility = 'Visible';
}
for (var i = 0; i < geenAntwBorders.length; i++) {
geenAntwBorders[i].Visibility = 'Visible';
}
} else if (aantalKliks == 1) {
for (var i = 0; i < correcteBorders.length; i++) {
correcteBorders[i].Visibility = 'Collapsed';
}
for (var i = 0; i < incorrecteBorders.length; i++) {
incorrecteBorders[i].Visibility = 'Collapsed';
}
for (var i = 0; i < geenAntwBorders.length; i++) {
geenAntwBorders[i].Visibility = 'Collapsed';
}
aantalKliks++;
}
function borderClicked(sender) {
for (var i = 0; i < correcteBorders.length; i++) {
correcteBorders[i].Visibility = 'Collapsed';
}
for (var i = 0; i < incorrecteBorders.length; i++) {
incorrecteBorders[i].Visibility = 'Collapsed';
}
for (var i = 0; i < geenAntwBorders.length; i++) {
geenAntwBorders[i].Visibility = 'Collapsed';
}
sender['Visibility'] = 'Visible';
}
The function OnCanvasClicked is triggered when I click anywhere in the canvas and makes all borders disappear/reappear. The function borderClicked is triggered when I click a specific border. The function borderClicked does trigger when I click a specific border, however the OnCanvasClicked function also gets executed right after, which causes an unwanted result.I think I need some way to ignore the OnCanvasClicked function if I click on a border, I did google this but to be honest I didn't really understand what they meant in most of the solutions, so I was hoping someone could explain it to me in a simple way what I need to do (and what I'm doing).
You need to set event.stopPropagation() when borderClicked function is fire
Try this which will prevent Javascript to further execution
event.preventDefault()
#Harshit is correct
You need to set event.stopPropagation() when borderClicked function is fire
I just wanted to add this link/sample which I found very usefull to understand bubbling

i want to write a short code i have multi contenteditable divs and i use a function to put the value of the div to a textarea please check with me
var myContentArr = ["myContent1", "myContent2", "myContent3", "myContent4", "myContent5", "myContent6"];
var hiddenArr = ["hidden1", "hidden2", "hidden3", "hidden4", "hidden5", "hidden6"];
function myFunction(){
for (var i = 0; i < hiddenArr.length; i++) {
document.getElementById(hiddenArr[i]).value =
for (var i = 0; i < myContentArr.length; i++) {
document.getElementById(myContentArr[i]).innerHTML
}
}
return true;
}
I wrote some JS that involves targeting the DOM, specifically a text input form. It only changes the display for the last element of the array when the user types in 95827. If the user types in 95828 or 95604, the display isn't filtered properly.
Here's a link to the full code.
I was told it may have to do with the removeDisplay function and how it's iterating through display (divs), but still can't manage to fix it.
Still new to DOM Manipulation.
var display = document.querySelectorAll(".display");
var zipCodeSearch = document.querySelector("#site-search");
var ants = document.querySelector("#ants");
const antZipCodes = [95828, 95604, 95827];
zipCodeSearch.addEventListener('change', function(e) {
// for(var i = 0; i < antZipCode.length; i++) {
// if(antZipCode[i] === Number(e.target.value)) {
// removeDisplay(displayNone);
// addDisplay(ants);
// }
// }
pestDisplay(antZipCodes, ants, display, e);
});
function removeDisplay(items) {
for(var i = 0; i < items.length; i++) {
items[i].style.display = "none";
}
}
function addDisplay(item) {
item.style.display = "block";
}
function displayAll(items) {
for(var i = 0; i < items.length; i++) {
items[i].style.display = "block";
}
}
function pestDisplay(arr, id, display, e) {
for(var i = 0; i < arr.length; i++) {
if(arr[i] === Number(e.target.value)) {
removeDisplay(display);
addDisplay(id);
} else {
displayAll(display);
}
}
}
function albumCoverDisplay() {
var i = 0;
for (i = 0; i < albumCover.length; i++) {
albumCover[i].addEventListener("click", function() {
for (var i = 0; i < albumCover.length; i++) {
albumInfo[i].style.display = "none";
}
albumInfo[i].style.display = "block";
});
}
}
Looks like you want to be able to hide other albumCover elements on clicking one of them.
There are a couple of mistakes
Your inner for-loop re-localize the scope of i, use different variable
i's value (assuming another variable is used in inner for-loop) will not remain same when the click will happen.
Make it
function albumCoverDisplay()
{
for (let i = 0; i < albumCover.length; i++) //use let instead of var
{
albumCover[i].addEventListener("click", function() {
for (var j = 0; j < albumCover.length; j++)
{
albumInfo[j].style.display = "none";
}
albumInfo[i].style.display = "block";
});
}
}
How to rewrite this code from jQuery to vanilla JavaScript? I need to see how many checkboxes are checked. The problem is I do not know how to remove unchecked checkboxes from the total score.
$(function () {
var countChecked = function () {
var n = $("input:checked").length;
$(".output").text(n);
};
countChecked();
$("input[type=checkbox]").on("click", countChecked);
});
What should I do next?
var box = document.querySelectorAll('form input');
var par = document.querySelector('.output');
var great = 0;
for (var i = 0; i < box.length; i++) {
box[i].addEventListener('click', countIt);
function countIt() {
for (var i = 0; i < box.length; i++) {
if ( box[i].checked ) {
great++
par.innerHTML = great;
return
}
}
}
}
You need to reset the great variable each time you count (for example by moving it inside the countIt function).
var box = document.querySelectorAll('form input');
var par = document.querySelector('.output');
function countIt() {
var great = 0;
for (var i = 0; i < box.length; i++) {
if (box[i].checked) {
great++;
}
}
par.innerHTML = great;
}
for (var i = 0; i < box.length; i++) {
box[i].addEventListener('click', countIt);
}
You can also move the countIt function definition out of the loop and the same with innerHTML setting.
I am using this code and data in variable is also changing how to avoid changes done in variable. For each loop I am using is cause. Or need to do any changes.
var str='',
b=gv_chartDataModel,a=[];
if(selkeyword!=="IF"){
a=gv_contextData;
}else{
for (var j = 0; j < 2; j++) {
var source = b.children[j];
for (var i = 0; i < source.children.length; i++) {
a.push(source.children[i])
}
}
}
var val = this.value;
for(var i=0;i<a.length;i++){
var temp_array=[];
a[i].children.forEach(function(d){
if(d.description.indexOf(val) !==-1){
temp_array.push(d);
}else{
a[i].children.push(d);
}
});
a[i].children=temp_array;
}
