In the following code, I have some divs with <a> tags, each containing a href of /User.aspx?ID=[some ID]. I wish to click the Delete <a> tag under the parent of the parent of the parent of any divs with duplicate ID's in the href.
Here is my code:
var z = 0;
var info = {};
$("a:contains('Delete')").each(function() {
z++;
var x = $(this).parent().parent().parent().find("span.UserLink a").attr("href");
var id = x.replace("/User.aspx?ID=", "");
info[z] = id;
console.log(info[z]);
});
var uniqueIds = {};
$.each(info, function(i, el){
if($.inArray(el, uniqueIds) === -1) { uniqueIds.push(el) }
else { $("html").find("span.UserLink a[href='/User.aspx?ID='"+info[i]+"']").parent().parent().parent().find("a:contains('Delete')").click() }
});
Use arrays, not objects
Maybe just a typo, I think you wanted to use arrays for info and uniqueIds
var info = [];
var uniqueIds = [];
jQuery.each already provides an index
You don't need z
$("a:contains('Delete')").each(function(index) {
var x = $(this).parent().parent().parent().find("span.UserLink a").attr("href");
var id = x.replace("/User.aspx?ID=", "");
info[index] = id;
console.log(info[z]);
});
Use meaningful names
x and info aren't very good names, you could try (for example) userLinkHref and foundIds
You could store the delete button in the first loop and use it in the second loop
var foundDeleteLinks = [];
$("a:contains('Delete')").each(function() {
var $deleteLink = $(this);
var userLinkHref = $deleteLink.parent().parent().parent().find("span.UserLink a").attr("href");
var id = userLinkHref.replace("/User.aspx?ID=", "");
foundDeleteLinks.push({id:id,$deleteLink:$deleteLink});
console.log(id);
});
var uniqueIds = [];
$.each(foundDeleteLinks, function(i, deleteLink){
var id = deleteLink.id;
if($.inArray(id, uniqueIds) === -1) { uniqueIds.push(id) }
else {
deleteLink.$deleteLink.click();
}
});
You may be able to do it in one loop
var foundIds = [];
$("a:contains('Delete')").each(function() {
var $deleteLink = $(this);
var userLinkHref = $deleteLink.parent().parent().parent().find("span.UserLink a").attr("href");
var id = userLinkHref.replace("/User.aspx?ID=", "");
if($.inArray(id, foundIds) === -1) { foundIds.push(id) }
else { $deleteLink.click(); }
});
I hope that helps enough to find your problems.

I have a loop in which I am calling rec_append() recursively, apparently the first pass alone works, then the loop stops.
I have an array of 4 elements going into that $.each loop but I see only the first element going into the function recursively. Help!
I switched it for a element.forEach but that gives me only the second element and I am stuck, is there a better solution to process a tree of elements? My array is a part of a tree.
var data = JSON.parse(JSON.stringify(result))
var graph = $(".entry-point");
function rec_append(requestData, parentDiv) {
var temp_parent_details;
$.each(requestData, function (index, jsonElement) {
if (typeof jsonElement === 'string') {
//Element construction
//Name and other details in the form of a : delimited string
var splitString = jsonElement.split(':');
var details = document.createElement("details");
var summary = document.createElement("summary");
summary.innerText = splitString[0];
details.append(summary);
temp_parent_details = details;
parentDiv.append(details);
var kbd = document.createElement("kbd");
kbd.innerText = splitString[1];
summary.append(' ');
summary.append(kbd);
var div = document.createElement("div");
div.className = "col";
details.append(div);
var dl = document.createElement("dl");
div.append(dl);
var dt = document.createElement("dt");
dt.className = "col-sm-1";
dt.innerText = "Path";
div.append(dt);
var dd = document.createElement("dd");
dd.className = "col-sm-11";
dd.innerText = splitString[2];
div.append(dd);
var dt2 = document.createElement("dt");
dt2.className = "col-sm-1";
dt2.innerText = "Type";
div.append(dt2);
var dd2 = document.createElement("dd");
dd2.className = "col-sm-11";
dd2.innerText = splitString[1];
div.append(dd2);
} else {
$.each(jsonElement, function (jsonElementArrIndx, jsonChildElement) {
rec_append(jsonChildElement, temp_parent_details); //Only 1 pass works, rest skip
});
}
});
}
rec_append(data, graph);
Sample data:enter image description here
I developed the store locator using open street map and leaflet. The problem is when I want to type in searchbox it will become lagging to finish the word. That store locator read from the CSV file that has 300++ data. Below is the code for the searchbox:
var locationLat = [];
var locationLng = [];
var locMarker;
var infoDiv = document.getElementById('storeinfo');
var infoDivInner = document.getElementById('infoDivInner');
var toggleSearch = document.getElementById('searchIcon');
var hasCircle = 0;
var circle = [];
//close store infor when x is clicked
var userLocation;
$("#infoClose").click(function() {
$("#storeinfo").hide();
if (map.hasLayer(circle)) {
map.removeLayer(circle);
}
});
var listings = document.getElementById('listingDiv');
var stores = L.geoJson().addTo(map);
var storesData = omnivore.csv('assets/data/table_1.csv');
function setActive(el) {
var siblings = listings.getElementsByTagName('div');
for (var i = 0; i < siblings.length; i++) {
siblings[i].className = siblings[i].className
.replace(/active/, '').replace(/\s\s*$/, '');
}
el.className += ' active';
}
function sortGeojson(a,b,prop) {
return (a.properties.name.toUpperCase() < b.properties.name.toUpperCase()) ? -1 : ((a.properties.name.toUpperCase() > b.properties.name.toUpperCase()) ? 1 : 0);
}
storesData.on('ready', function() {
var storesSorted = storesData.toGeoJSON();
//console.log(storesSorted);
var sorted = (storesSorted.features).sort(sortGeojson)
//console.log(sorted);
storesSorted.features = sorted;
//console.log(storesSorted)
stores.addData(storesSorted);
map.fitBounds(stores.getBounds());
toggleSearch.onclick = function() {
//var s = document.getElementById('searchbox');
//if (s.style.display != 'none') {
//s.style.display = 'yes';
//toggleSearch.innerHTML = '<i class="fa fa-search"></i>';
//$("#search-input").val("");
//search.collapse();
//document.getElementById('storeinfo').style.display = 'none';
//$('.item').show();
//} else {
//toggleSearch.innerHTML = '<i class="fa fa-times"></i>';
//s.style.display = 'block';
//attempt to autofocus search input field when opened
//$('#search-input').focus();
//}
};
stores.eachLayer(function(layer) {
//New jquery search
$('#searchbox').on('change paste keyup', function() {
var txt = $('#search-input').val();
$('.item').each(function() {
if ($(this).text().toUpperCase().indexOf(txt.toUpperCase()) != -1) {
$(this).show();
} else {
$(this).hide();
}
});
});
I dont know what is the cause of the lag in the search box. It is something wrong in code or the csv file? Thank you
Every iteration of $('.item').each is causing a layout change because $(this).hide() or $(this).show() causes the item to removed/added to the DOM as the style is set to display:none back and forth. DOM manipulations and the corresponding layout changes are expensive.
You can consider accumulating the changes and doing one batch update to the DOM using a function like appendChild
I have a ToDo list, using localStorage... I need to be able to remove the item from the ToDo list... I try to use "dataArray.splice();" But the problem is I don't know how i can remove the object when the position is unknown...
function getTodoItems() {
for (var i = 0; i < dataArray.length; i++) {
if (!dataArray[i].listItem.length) return;
var itemList = document.getElementById("my-todo-list");
var list = document.createElement("li");
itemList.appendChild(list);
list.innerHTML = dataArray[i].listItem;
var spanItem = document.createElement('span');
spanItem.style.float = 'right';
var myCloseSymbol = document.createTextNode('\u00D7');
spanItem.classList.add("closeBtn");
spanItem.appendChild(myCloseSymbol);
listItems[i].appendChild(spanItem);
close[i].onclick = function() {
var div = this.parentElement;
div.style.display = "none";
console.log(dataArray);
}
var list = document.getElementsByTagName('li');
list[i].onclick = function() {
this.classList.toggle("checked");
}
}
}
Then probably get its position:
const position = dataArray.indexOf(/*whatever*/);
dataArray.splice(position, 1);
You can get the position of the element using 'indexOf'
let pos = dataArray.indexOf(element);
dataArray.splice(pos,1)
IndexOf() wont work if you are trying to find the index of an entire object or array inside the array.
If you need to find the index of an entire object inside your array, you test each one's value to find out if it is the correct one. I would use findIndex();
Try this in your console:
var array = [];
for (var i = 0; i < 10; i++ ){ array.push({item: i}) }
console.log('Current Array: ', array);
var indexOfResult = array.indexOf({item: 3});
console.log('indexOf result: ',indexOfResult);
var findIndexResult = array.findIndex(object => object.item === 3);
console.log('findIndex result: ',findIndexResult)
I have a textarea where I paste a block of HTML code. When I hit submit, I want to extract all CSS classes and ID's from that block and throw them into an array.
So far I have the submit working as well as the regular expression, but i don't know how to filter through the whole block and extract all instances where text matches my regular expression.
index.html
<body>
<textarea id="codeInput"></textarea>
<button id="submitCode">submit</button>
<script src="functions.js"></script>
</body>
function.js
$(function() {
$('#submitCode').click(function() {
var codeInput = $('textarea#codeInput').val();
console.log(codeInput);
});
});
$('#submitCode').click(function() {
var codeInput = $('textarea#codeInput').val();
var codeHTML = $('<div>', { html: codeInput }); // Parse the input as HTML
var allIds = [];
var allClasses = [];
codeHTML.find('[id]').each(function() {
allIds.push(this.id);
});
codeHTML.find('[class]').each(function() {
allClasses = allClasses.concat(this.className.split(' '));
});
console.log("IDs: " + allIds.join(', '));
console.log("Classes: " + allClasses.join(', '));
});
Make your function.js something like this:
$(function() {
$('#submitCode').click(function() {
var codeInput = $('textarea#codeInput').val();
var $input = $(codeInput);
var attrs: {
'class': [],
'id': []
};
$input.find('*').each(function() {
attrs.class.push($(this).attr('class'));
attrs.id.push($(this).attr('id'));
});
attrs.class.push($input.attr('class'));
attrs.id.push($input.attr('id'));
});
});
That goes through each element in the input code, and removes their class and id attributes, by first going through all the children of the container element in the input, and then afterwards doing the same for the container element in the input.
Personally I like Barmar's solution the best, but this works (jsfiddle):
$('#submitCode').click(function() {
var codeInput = $('#codeInput').val();
var ids = codeInput.match(/id="(.*?)"/);
var classes = codeInput.match(/class="(.*?)"/);
var output = classes[1].split(" ");
output.push( ids[1] );
console.log(output);
});
$(function() {
$('#submitCode').click(function() {
var ids = [], classes = [];
$("[id],[class]").each(function(i, el) {
var id, c;
if (id = $(this).attr('id')) {
ids.push(id);
}
if (c = $(el).attr('class')) {
classes.push(c);
}
});
console.log(ids, classes);
});
});
<textarea id="codeInput">
<div id="hello"><div class="w"></div></div>
<div id="world"></div>
<div class="my-class"></div>
</textarea>
<button id="submitCode">submit</button>
$(function() {
$('#submitCode').click(function() {
var CSS_CLASSES = [];
var CSS_IDS = [];
var el = document.createElement( 'div' );
var text = $("#codeInput").val();
el.innerHTML = text;
var nodes = el.getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++) {
var node = nodes[i];
if(node.id.length > 0) {
CSS_IDS.push(node.id);
}
if(node.className.length > 0) {
CSS_CLASSES.push(node.className);
}
}
console.log(CSS_CLASSES);
console.log(CSS_IDS);
});
});

I had this very same challenge and modified the code by #Ryan to extract all (unique) classes and IDs, including when multiple classes are applied to the same element. It's very useful and works for any URL.
See http://jsfiddle.net/pixelfast/4uftwbm0/57/
Thank you.

i got an anchor in the DOM and the following code replaces it with a fancy button. This works well but if i want more buttons it crashes. Can I do it without a for-loop?
$(document).ready(buttonize);
function buttonize(){
//alert(buttonAmount);
//Lookup for the classes
var button = $('a.makeabutton');
var buttonContent = button.text();
var buttonStyle = button.attr('class');
var link = button.attr('href');
var linkTarget = button.attr('target');
var toSearchFor = 'makeabutton';
var toReplaceWith = 'buttonize';
var searchButtonStyle = buttonStyle.search(toSearchFor);
if (searchButtonStyle != -1) {
//When class 'makeabutton' is found in string, build the new classname
newButtonStyle = buttonStyle.replace(toSearchFor, toReplaceWith);
button.replaceWith('<span class="'+newButtonStyle
+'"><span class="left"></span><span class="body">'
+buttonContent+'</span><span class="right"></span></span>');
$('.buttonize').click(function(e){
if (linkTarget == '_blank') {
window.open(link);
}
else window.location = link;
});
}
}
Use the each method because you are fetching a collection of elements (even if its just one)
var button = $('a.makeabutton');
button.each(function () {
var btn = $(this);
var buttonContent = btn.text();
var buttonStyle = btn.attr('class');
var link = btn.attr('href');
var linkTarget = btn.attr('target');
var toSearchFor = 'makeabutton';
var toReplaceWith = 'buttonize';
var searchButtonStyle = buttonStyle.search(toSearchFor);
...
};
the each method loops through all the elements that were retrieved, and you can use the this keyword to refer to the current element in the loop
var button = $('a.makeabutton');
This code returns a jQuery object which contains all the matching anchors. You need to loop through them using .each:
$(document).ready(buttonize);
function buttonize() {
//alert(buttonAmount);
//Lookup for the classes
var $buttons = $('a.makeabutton');
$buttons.each(function() {
var button = $(this);
var buttonContent = button.text();
var buttonStyle = button.attr('class');
var link = button.attr('href');
var linkTarget = button.attr('target');
var toSearchFor = 'makeabutton';
var toReplaceWith = 'buttonize';
var searchButtonStyle = buttonStyle.search(toSearchFor);
if (searchButtonStyle != -1) {
newButtonStyle = buttonStyle.replace(toSearchFor, toReplaceWith);
button.replaceWith('<span class="'
+ newButtonStyle
+ '"><span class="left"></span><span class="body">'
+ buttonContent
+ '</span><span class="right"></span></span>');
$('.buttonize').click(function(e) {
if (linkTarget == '_blank') {
window.open(link);
} else window.location = link;
}); // end click
} // end if
}); // end each
}
