I am using the selected images only is going to next page. If I have selected the image like(1,2,3), after this I unselected the image (3). On next page I was getting all the images(1,2,3). I don't want unselected image(3). I have tried localStroage.removeItem but all the images are getting removed. But I want to remove only the unselected image.
<script>
localStorage.clear();
$(document).ready(function () {
$('.blur').on('click', function(){
var $$ = $(this);
if( !$$.is('.checked'))
{
$$.addClass('checked');
$('#imgCheck').prop('checked', true);
documentid =''
var name=$(this).attr('id');
//alert(name);
var test = localStorage.getItem("test");
//alert(test);
var obj = [];
if(test)
{
obj= JSON.parse(test);
}
obj.push({"id": name});
localStorage.setItem("test",JSON.stringify(obj));
console.log(obj);
}
else
{
$$.removeClass('checked');
$('#imgCheck').prop('checked', false);
var name=$(this).attr('id');
//alert(name);
var test = localStorage.removeItem("test");
console.log(image);
}
})
});
please suggest me..

So, in plain terms I am creating a Chrome Extension that so far can only save links from the internet but not delete them. What I want to add is a "remove" button for deleting unwanted links. So far I haven't got that to work.
The buttons I want to remove are added using JavaScript. Each new block of HTML features a "remove" button but clicking that button does nothing. I have tried binding listeners to each element using a for loop but that doesn't seem to work.
The code runs without errors and I'm certain that the issue is a slight oversight but I have only just started using JavaScript so I'm lost for solutions at the moment.
I have included all the code because I don't want to leave out anything that might be imperative to finding a solution.
It starts with the code for adding a link, followed by removing a single link and then removing all links at once. Thank you all for any help, really want to get this working.
https://github.com/mmmamer/Drop Repository for the rest of the code. Mainly popup.html and popup.css.
var urlList = [];
var i = 0;
document.addEventListener('DOMContentLoaded', function() {
getUrlListAndRestoreInDom();
// event listener for the button inside popup window
document.getElementById('save').addEventListener('click', addLink);
});
function addLink() {
var url = document.getElementById("saveLink").value;
addUrlToListAndSave(url);
addUrlToDom(url);
}
function getUrlListAndRestoreInDom() {
chrome.storage.local.get({
urlList: []
}, function(data) {
urlList = data.urlList;
urlList.forEach(function(url) {
addUrlToDom(url);
});
});
}
function addUrlToDom(url) {
// change the text message
document.getElementById("saved-pages").innerHTML = "<h2>Saved pages</h2>";
var newEntry = document.createElement('li');
var newLink = document.createElement('a');
var removeButton = document.createElement('button');
removeButton.textContent = "Remove";
//removeButton.createElement('button');
removeButton.type = "button";
removeButton.className = "remove";
newLink.textContent = url;
newLink.setAttribute('href', url);
newLink.setAttribute('target', '_blank');
newEntry.appendChild(newLink)
newEntry.appendChild(removeButton);
newEntry.className = "listItem";
document.getElementById("list").appendChild(newEntry);
}
function addUrlToListAndSave(url) {
urlList.push(url);
saveUrlList();
//}
}
function saveUrlList(callback) {
chrome.storage.local.set({
urlList
}, function() {
if (typeof callback === 'function') {
//If there was no callback provided, don't try to call it.
callback();
}
});
}
// remove a single bookmark item
document.addEventListener('DOMContentLoaded', function() {
getUrlListAndRestoreInDom();
var allButtons = document.getElementsByClassName('remove');
function listenI(i) {
allButtons[i].addEventListener('click', () => removeMe(i));
}
for (var i = 0; i < allButtons.length; i++) {
listenI(i);
}
});
function removeMe(i) {
var fullList = documents.getElementsByClassName('listItem');
listItem[i].parentNode.removeChild(listItem[i]);
}
//remove all button
document.addEventListener('DOMContentLoaded', function() {
document.getElementById("remove-all").addEventListener('click', function() {
var removeList = document.getElementsByClassName("listItem");
while(removeList[0]) {
removeList[0].parentNode.removeChild(removeList[0]);
}
})
});
chrome.storage.local.get() is asynchronous. So when you try to add the event listeners to the Remove buttons, they're not in the DOM yet.
You can add the listener in the addUrlToDom() function instead. That way you'll also add the event listener when you create new buttons.
function addUrlToDom(url) {
// change the text message
document.getElementById("saved-pages").innerHTML = "<h2>Saved pages</h2>";
var newEntry = document.createElement('li');
var newLink = document.createElement('a');
var removeButton = document.createElement('button');
removeButton.textContent = "Remove";
//removeButton.createElement('button');
removeButton.type = "button";
removeButton.className = "remove";
newLink.textContent = url;
newLink.setAttribute('href', url);
newLink.setAttribute('target', '_blank');
newEntry.appendChild(newLink)
newEntry.appendChild(removeButton);
removeButton.addEventListener("click", function() {
var anchor = this.previousElementSibling;
var url = anchor.getAttribute("href");
removeUrlAndSave(url);
this.parentNode.remove();
});
newEntry.className = "listItem";
document.getElementById("list").appendChild(newEntry);
}
function removeUrlAndSave(url) {
var index = urlList.indexOf(url);
if (index != -1) {
urlList.splice(index, 1);
saveUrlList();
}
}
I have two codemirror editors on one page. A drop down list of items and radio group to target the correct editor.
What I want to do is on change of the drop down list insert the value of the item into the targeted editor (deleted by the radio group).
my code is as below: however the function isnt working. When I alert the item value and the target I get expected results, however the function to insert the text is failing:
<script type="text/javascript">
function editor(id) {
var editor = CodeMirror.fromTextArea(id, {
continuousScanning: 500,
lineNumbers: true
});
editor.setSize(null, 550);
}
var config_id = document.getElementById('id_config')
var config = editor(config_id);
var remote_config_id = document.getElementById('id_remote_config')
var remote_config = editor(remote_config_id);
function insertStringInTemplate(str, target) {
if (target== "id_config") {
var doc = config
} else {
var doc = remote_config
}
var cursor = doc.getCursor();
var pos = {
line: cursor.line,
ch: cursor.ch
}
doc.replaceRange(str, pos);
}
$(function(){
// bind change event to select
$('#template_vars').on('change', function () {
var var_data = $(this).val(); // get selected value
var var_target = $('input[name=target]:checked').val();
insertStringInTemplate(var_data, var_target)
return false;
});
});
$("#template_vars").chosen({no_results_text: "Oops, nothing found!"});
</script>
however the function to insert the text is failing
That function (i.e. insertStringInTemplate()) is working good/properly; however, the problem is with the editor() function, where you forgot to return the editor (i.e. the CodeMirror instance).
So a simple fix would be:
function editor(id) {
var editor = CodeMirror.fromTextArea(id, {
continuousScanning: 500,
lineNumbers: true
});
editor.setSize(null, 550);
return editor; // <- here's the fix
}
Demo on CodePen.
However in that demo, I added an if block to the insertStringInTemplate() function, as in the following code:
function insertStringInTemplate(str, target) {
if (target== "id_config") {
var doc = config
} else {
var doc = remote_config
}
// If there's a selection, replace the selection.
if ( doc.somethingSelected() ) {
doc.replaceSelection( str );
return;
}
// Otherwise, we insert at the cursor position.
var cursor = doc.getCursor();
var pos = {
line: cursor.line,
ch: cursor.ch
}
doc.replaceRange(str, pos);
}
Planning to get the specific ID values from the selection on the HTML page (selection here means checked boxes). Here is my code for a button click event(button will fetch the row numbers or ids):
$("a", button).click(function () {
$('#groups').find('tr').each(function () {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
console.log($(this));
}
});
});
This returns addtional information on rows + tr tag, however, I just want the ID part of it. Here is sample output I am getting out of above code:
[tr#row-12150.row.oddSelected, context: tr#row-12150.row.oddSelected]
[tr#row-12151.row.evenSelected, context: tr#row-12151.row.evenSelected]
This means I have selected 12150 and 12151 out of the #groups table. How do I just pull the row numbers 12150 and 12151 and not the entire detailed output and I want this to store in an array/(JS array) for multiple row numbers.
You have the row as per the .find('tr'), your should just be able to go:
console.log($(this).attr('id')); //this should show the id in your console.
so your code becomes:
$("a", button).click(function () {
$('#groups').find('tr').each(function () {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
console.log($(this).attr('id'));
}
});
});
Then to just get the number you can use:
var number = $(this).attr(id).split('-')[1] //assuming it's always row-<<some number>>
putting it all together:
$("a", button).click(function () {
$('#groups').find('tr').each(function () {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
var number = $(this).attr('id').split('-')[1] //assuming it's always row-<<some number>>;
console.log(number);
}
});
});
To store it in an array:
$("a", button).click(function () {
var checkedRows = []; //define empty array.
var count = 0; //keep a counter to use for the array.
$('#groups').find('tr').each(function () {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
var number = $(this).attr('id').split('-')[1];
checkedRows[count] = number; //add the number to our array.
count++; //increase the count
}
});
});
Make sure your form and your button have id's first then try this instead:
$('#buttonId').click(function(){
$('#formId input:checked').each(i, e){
console.log($(e).attr('id'));
}
});
I have a server that dynamically(asp.net ) generate webpages that I can't alter.
On all pages I would like to capture all buttons clicked.
In JSFiddle https://jsfiddle.net/forssux/aub2t6gn/2/ is an example..
$(".checkout-basket").click (function ()
The first alert shows the 3 possible values,
but not the chosen item..
$(".button.button-dl").click(function ()
In jsfiddle this part doesn't get executed
Strangely on my real webpage I get the button clicked...but when I put it in the If then construction it fails to console.log the chosen item..
I hope somebody can explain me how to get these..
Kind Regards
Guy Forssman
//$("div.detail-info,table.checkout-basket").click(function () {

// console.log(knopje + " knopje was clicked");

// capture click on download button in checkout-basket page
$(".checkout-basket").click (function () {
basket =[];
item="";
str = $(this).text();
str = str.replace(/\s\s+/g, ' ');
var str = str.match(/("[^"]+"|[^"\s]+)/g);
console.log("Array ",str);
for(var i=0;i<str.length;i++){
if(str[i] === "verwijder"){
console.log("Item= ",str[i+1]);
item = str[i+1];
basket.push(item);}
}
console.log("Basket contains ",basket);
//console.log("idValBasket ",idVal);
var test = idVal.replace(/\$/gi, "_").slice(0,-6);
console.log("test ",test);
var element = test.substr(test.length - 2)-1;
console.log("element ",element);
element=element-1;
item = basket[element];
console.log("Item finaal is ",item);
});
$(".button.button-dl").click(function () {
var addressValue = $(this).attr('href');
console.log("addresValue Basket",addressValue );
var re = /'(.*?)'/;
var m = addressValue.match(re);
console.log (" m basket is ",m);
if (m != null)
idVal = (m[0].replace(re, '$1'));
console.log("idVal Basket",idVal);
});
//This section captures the download in the detail page
$(".button").click(function () {
var downloadItem = document.getElementsByTagName("h1")[0].innerHTML
console.log("addresValue detail",downloadItem );
});
I never use click function, use on(*event*,...) instead:
$(".checkout-basket").on("click", function (){ /* CODE */ });
Check if visually there are a layout over the a layuot (a div, span, etc.)
Maybe a strange question and maybe i got it wrong, but why do you use push ?? if you want to delete an item ? btw also the example isn't working so maybe that is your problem
I am trying to code my own image gallery using html css jquery. I have a modal window to show the clicked in images. Inside my modal window I have a previous and next button.
My question is how can i show the previous images or next images when someone click that button.
Here's my jsFiddle
jquery code i am using to show clicked in images.
$(function(){
$('.gallery a').click(function(evt) {
evt.preventDefault( );
var imgPath = $(this).attr('href');
$('.gallery-overlay').show()
.find('.gallery-image').attr('src',imgPath);
return false;
});
});
Add this to your jQuery.
Declare a variable current image in your function and keep current image saved in that variable. Update the variable whenever current image is changed.
Updated jsfiddle
Click on the second image in the images and see the prev and next image then.
$('.gallery-control-previous').click(function(){
var imgPath = current_img.prev().attr('href');
current_img = current_img.prev();
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});
$('.gallery-control-next').click(function(){
var imgPath = current_img.next().attr('href');
current_img = current_img.next();
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});
If you have understood this answer, add checks to the code showing next, prev elemments only when they exist.
You can find how to do that,
here..
Updated.
Get the first child of next row, and pass that.
$('.gallery-control-next').click(function(){
if(current_img.next().length){
current_img = current_img.next();
}else{
current_img = current_img.parents(".row").next(".row").find("a:first");
}
var imgPath = current_img.attr('href');
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});
I have added img_no to each a tag to identify the current active image and get next or previous image
Working Demo
$(function () {
$('.gallery a').click(function (evt) {
evt.preventDefault();
var imgPath = $(this).attr('href');
var img_no = $(this).attr('img_no');
$('.gallery-overlay').show()
.find('.gallery-image').attr('src', imgPath).attr('img_no', img_no);
return false;
});
});
i = 1;
$('.row a img').each(function () {
$(this).attr('img_no', i);
$(this).parents('a').attr('img_no', i);
i++;
});
images_length = i - 1;
console.log(images_length);
$('.gallery-control-next').click(function () {
var img_no = $(this).parent().parent().find('.gallery-image').attr('img_no');
img_no++;
if (img_no > images_length) {
img_no = 1;
}
$('.row a').each(function () {
if ($(this).attr('img_no') == img_no) {
imgPath = $(this).attr('href');
}
});
$('.gallery-imagebox img').attr('src', imgPath).attr('img_no', img_no);
});
$('.gallery-control-previous').click(function(){
var img_no = $(this).parent().parent().find('.gallery-image').attr('img_no');
img_no--;
if (img_no <= 0) {
img_no = images_length;
}
$('.row a').each(function () {
if ($(this).attr('img_no') == img_no) {
imgPath = $(this).attr('href');
}
});
$('.gallery-imagebox img').attr('src', imgPath).attr('img_no', img_no);
});
