I am unable to get the href link of anchor. I created elements dynamically in loop in jquery. Please help me out how to get the link address.
function setGrid(){
// get List of all Avatars...
var arr = ['MMA','MMB','MMC','MMD','MME','MMF','MMG','MWA','MWB','MWC','MWD','MWE','MWF','MWG'];
for(var i=0;i<arr.length;i++)
{
var d = "<a class='testClick' href='../../images/avatars/"+arr[i]+".png'>"+
"<img src='../../images/avatars/"+
arr[i]+".png' id='"+arr[i]+"' alt='avatar' style='height:120px;width:120px; margin-left:10px'></a>";
$( "div.modal-body" ).append( d );
}
}
Below is how I'm trying to access the link with onclick listener:
$(document).ready(function(){
$(".testClick").click(function () {
var value = $(this).attr('href');
alert(value );
});
});`
I'm unable to get the href. Please help me out.
Your above code works fine; it correctly alerts out the href attribute.
The only thing you're missing is to prevent the click actually taking you to that link. This can be done by passing e into your .click() function for .testClick, and then calling e.preventDefault() to prevent the default click behaviour:
function setGrid() {
// get List of all Avatars...
var arr = ['MMA', 'MMB', 'MMC', 'MMD', 'MME', 'MMF', 'MMG', 'MWA', 'MWB', 'MWC', 'MWD', 'MWE', 'MWF', 'MWG'];
for (var i = 0; i < arr.length; i++) {
var d = "<a class='testClick' href='../../images/avatars/" + arr[i] + ".png'>" +
"<img src='../../images/avatars/" +
arr[i] + ".png' id='" + arr[i] + "' alt='avatar' style='height:120px;width:120px; margin-left:10px'></a>";
$("body").append(d);
}
}
setGrid();
$(document).ready(function() {
$(".testClick").click(function(e) {
e.preventDefault();
var value = $(this).attr('href');
alert(value);
});
});

I have this array:
var names = [
"Name1",
"Name2",
"Name3"
];
I converted this to Unorder List for HTML:
for(i = 0; i < names.Length; i++){
text += "<li>" + names[i] + "</li>";
}
text += "</ul>";
document.getElementById("choices").innerHTML = text;
Now, I got this:
Name1
Name2
Name3
And I am happy with the result. But now I want if someone click on Name2 so it alert me the index of the value. What I want is it should in Mobile App (Cordova) so that when user click on List Item it will show details on other activity (Some other page).
PS:
I checked:
var index = $( "li" ).index( this );
and
var index = $("ul li.active").index();
But seems like these are not made for me.
May be I should Dynamically assign ID's to each <li> item? What should I do now?
You can directly get index using index method.
$("li").click(function () {
alert($(this).index());
});
If you have multiple ul elements on page and you want to bind click event to some specific element you can do this.
To bind click on element by id
$("#YourUlId li").click(function () {
alert($(this).index());
});
To bind click event by class
$(".YourUlClass li").click(function () {
alert($(this).index());
});
$( "li" ).index will return elements index with respect to all li elements in DOM.
You need to use .index() with jquery object of clicked element. It will return the elements index in its parent container:
var index = $(this).index();
Pass the id dynamically in for loop
for(i = 0; i < names.Length; i++){
text += "<li id="+i+">" + names[i] + "</li>";
}
assign the click event, u will get the id by below code
$(li).click(function(){
alert($(this).attr("id"));
});
use this for getting the current element
<ul>
<li>Male</li>
<li>Female</li>
</ul>
<script>
$("li").click(function(){
alert($(this).index())
})
</script>
See below working snippet
var names = [
"Name1",
"Name2",
"Name3"
];
var text='<ul>';
for(i = 0; i < names.length; i++){
text += "<li>" + names[i] + "</li>";
}
text += "</ul>";
document.getElementById("choices").innerHTML = text;
$('li').on('click',function(){
alert($(this).index())
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="choices"></div>
Using native javascript, you can just create a function that will alert the index of the array value corresponding the li element value/id
First you attach the function on the choices
document.getElementById('Name2').setAttribute('onclick','checkIndex(this)');
then loop through the array and hunt for the matching array value
function checkIndex(item){
for(i=0;i<names.length;i++){
if(names[i] == item.innerHTML){ //or item.id
alert(names.indexOf(names[i]));
}
}
}
I would handle it in a declarative way, using html data-attributes, handled by jquery. see here
Here's an example.
var names = ["jack", "mary", "lou", "andrew"];
var text = "<ul>";
for (var i = 0; i < names.length; i++) {
text += "<li data-id='" + i + "'>" + names[i] + "</li>";
}
text += "</ul>";
document.getElementById("choices").innerHTML = text;
$("li").click(function(e){
alert($(this).data("id"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<body>
My Choice
<div id="choices"></div>
</body>
</html>
Of course you can change data-id with whatever you want, or either add other attributes (data-page ? data-txt ? ) and handle all this in a proper way.
Also, dynamically assign ids to your list is a possibility, but I prefer this because I find it more flexible.
I don't have many knowlege in javascript so I don't know what is the problem here,
I create divs dynamically in js and each div call a function when is clicked but the function is not recongized. This is part of the code
for (......) {
var listatema = document.createElement("div");
listatema.innerHTML += "<a href='javascript: void(0)' onClick='functest(" + pag + ")'>" + temat + "</a>";
document.getElementById('menu').appendChild(listatema);}
}
"tema" is a text, the function "functest" has an argument "pag[aux]", this is a number.
The function is:
function functest(arg){
console.log(arg)
}
other alternative that i tried is change that: onClick='"+ functest(pag) +"':
i change the position of Quotation marks "" and the function work good but it is executed when the page is loaded, it don't wait to do click.
Your code should work if you're doing something like:
function functest(arg) {
console.log(arg);
}
for (var i = 0; i < 10; i++) {
var listatema = document.createElement("div");
listatema.innerHTML += "<a href='javascript: void(0)' onClick='functest(" + i + ")'>" + i + "</a>";
document.getElementById('menu').appendChild(listatema);
}
<div id="menu"></div>
I would, however, recommend using addEventListener or setting the onClick handler on the document element object rather than setting the innerHTML. Note that setting innerHTML is not advised, especially when rendering user input. See https://developer.mozilla.org/en-US/docs/Web/API/Element/innerHTML#Security_considerations. In your case, it probably isn't really an issue, but it's good practice to avoid it if you can :)
for (var i = 0; i < 5; i++) {
var wrapper = document.createElement("div");
var listatema = document.createElement("a");
listatema.textContent = i;
listatema.href = "javascript:void(0)";
listatema.addEventListener('click', function(e) {
console.log(this.i);
}.bind({ i : i }));
wrapper.appendChild(listatema);
document.getElementById('menu').appendChild(wrapper);
}
<div id="menu"></div>
onClick='functest(\""+ pag +"\")'
you forgot to quote the parameter.
I am using Select2 for dropdown styling from http://ivaynberg.github.io/select2/ .
I have several dropdowns on the page which are styled correctly using the following:
<script>
$(document).ready(function() {
$("#dropdown1").select2();
$("#dropdown2").select2();
});
</script>
Now, I have another option on the page where it allows the user to add as many dropdowns as they want for additional options, the following way:
<img src="images/add.png" title="Add Row" border="0" onclick="addRowToCountryPrice('',''); return false;">
<input type="hidden" name="TotalLinesCountry" id="TotalLinesCountry">
<script>
var arr = new Array();
var ind=0;
function showCountryDrop(name1,sel, param){
var dval="";
dval = "<select name=\"" + name1 + "\" id=\"" + name1 + "\" class=\"countriesclass\">";
dval += "<option value=\"\">Select Country</option>\r\n";
selVal = (sel==0001) ? "selected=\"selected\"" : " " ;
dval += "<option value=\"0001\" " + selVal + ">United Kingdom</option>";
selVal = (sel==0002) ? "selected=\"selected\"" : " " ;
dval += "<option value=\"0002\" " + selVal + ">United States</option>";
selVal = (sel==0003) ? "selected=\"selected\"" : " " ;
dval += "<option value=\"0003\" " + selVal + ">Albania</option>";
selVal = (sel==0004) ? "selected=\"selected\"" : " " ;
dval += "<option value=\"0004\" " + selVal + ">Algeria</option>";
dval +="</select>";
return dval;
}
function addRowToCountryPrice(country,price) {
var tbl = document.getElementById("tblCountryCurrency");
var lastRow = tbl.rows.length;
var iteration = lastRow;
var row = tbl.insertRow(lastRow);
var cellVal = "";
var cellLeft;
var i=0;
arr[ind] = (iteration+1);
cellLeft = row.insertCell(i++);
cellLeft.innerHTML = showCountryDrop("countryDrop_" + ind,country);
cellLeft = row.insertCell(i++);
var price = (price!=0) ? price : "0.00";
cellLeft.innerHTML = "<input type=\"text\" name=\"countryPrice_" + ind + "\" id=\"countryPrice_" + iteration + "\" value = \"" + price + "\" size=\"8\">";
cellLeft = row.insertCell(i++);
cellLeft.innerHTML = "<img src=\"images/delete.png\" title=\"Delete Row\" border=\"0\" onclick=\" removeRowFromTable(" + ind + "); return false;\">";
document.getElementById("TotalLinesCountry").value = (parseInt(ind)+1);
ind++;
}
function removeRowFromTable(src)
{
var tbl = document.getElementById("tblCountryCurrency");
var lastRow = tbl.rows.length;
if (arr[src]!="") tbl.deleteRow((arr[src]-1));
arr[src]="";
var counter = 1;
for( i=0; i<arr.length; i++) {
if (arr[i]!="") {
arr[i]= counter;
counter++;
}
}
return false;
}
</script>
While it generates the dropdowns correctly, they are not styled through the class "countriesclass", even if I do a:
$(".countriesclass").select2();
I also tried
dval +="</select>";
$(".countriesclass").select2();
return dval;
And that seems to be PARTIALLY working in a strange way. When I create the first dropdown, it doesn't get styled. When I create another second dropdown, then the first one gets styled but the second one doesn't. It then doesn't let me create further ones and shows an error.
Any ideas how I could get this working?
UPDATE: jsFiddle http://jsfiddle.net/y6af098z/2/
Your call to $('.countriesclass') goes off when the document is ready. But the select has not been added to the document yet, then. So no elements are found.
You should look up the added select after the user has clicked on the plus and you've added the select to the dom.
$('#plus').on('click', function () {
$tr = addRowToCountryPrice('Algeria', 0);
$('.countriesclass', $tr).select2();
});
The second argument $tr tells jquery only to look in the recently added table row, so that you only select the newly added select which is a child of the newly added tr. Not the selects in the other rows.
Like #dreamweiver already noted, you should make better use of jquery when creating the dom elements. That's what jquery is good at. I've updated the jsfiddle to show how you can create the select and table row the jquery way.
DEMO
Instead of using getelementbyId use getelementbyClass and give each dropdown a class, you can only have one getelementbyid.
Hope this helps. if you want i could send you the code for what you require?
The select2 when called was not able to find the dropdown list boxes,because they were added dynamically and hence the those were not visible for the jQuery class selector $(".countriesclass").select2();.
This type of behaviour can be overcome by referencing the selector from the document element, rather than referring the element directly like above. so the new selector should be like this
$(document).find("select.countriesclass").select2();
Also I have done few tunings in your code.

Note: one more thing, when using jQuery lib make sure you make the most of it, don't use raw JS code instead use the jQuery equivalent syntax for the same, which would be simple and easy to use.
I have created a html like this:
<body onload = callAlert();loaded()>
<ul id="thelist">
<div id = "lst"></div>
</ul>
</div>
</body>
The callAlert() is here:
function callAlert()
{
listRows = prompt("how many list row you want??");
var listText = "List Number";
for(var i = 0;i < listRows; i++)
{
if(i%2==0)
{
listText = listText +i+'<p style="background-color:#EEEEEE" id = "listNum' + i + '" onclick = itemclicked(id)>';
}
else
{
listText = listText + i+ '<p id = "listNum' + i + '" onclick = itemclicked(id)>';
}
listText = listText + i;
//document.getElementById("lst").innerHTML = listText+i+'5';
}
document.getElementById("lst").innerHTML = listText+i;
}
Inside callAlert(), I have created id runtime inside the <p> tag and at last of for loop, I have set the paragraph like this. document.getElementById("lst").innerHTML = listText+i;
Now I am confuse when listItem is clicked then how to access the value of the selected item.
I am using this:
function itemclicked(id)
{
alert("clicked at :"+id);
var pElement = document.getElementById(id).value;
alert("value of this is: "+pElement);
}
But getting value as undefined.
Any help would be grateful.
try onclick = itemclicked(this.id) instead of onclick = 'itemclicked(id)'
Dude, you should really work on you CodingStyle. Also, write simple, clean code.
First, the html-code should simply look like this:
<body onload="callAlert();loaded();">
<ul id="thelist"></ul>
</body>
No div or anything like this. ul and ol shall be used in combination with li only.
Also, you should always close the html-tags in the right order. Otherwise, like in your examle, you have different nubers of opening and closing-tags. (the closing div in the 5th line of your html-example doesn't refer to a opening div-tag)...
And here comes the fixed code:
<script type="text/javascript">
function callAlert() {
var rows = prompt('Please type in the number of required rows');
var listCode = '';
for (var i = 0; i < rows; i++) {
var listID = 'list_' + i.toString();
if (i % 2 === 0) {
listCode += '<li style="background-color:#EEEEEE" id="' + listID + '" onclick="itemClicked(this.id);">listItem# ' + i + '</li>';
}
else {
listCode += '<li id="' + listID + '" onclick="itemClicked(this.id);">listItem# ' + i + '</li>';
}
}
document.getElementById('thelist').innerHTML = listCode;
}
function itemClicked(id) {
var pElement = document.getElementById(id).innerHTML;
alert("Clicked: " + id + '\nValue: ' + pElement);
}
</script>
You can watch a working sample in this fiddle.
The problems were:
You have to commit the id of the clicked item using this.id like #Varada already mentioned.
Before that, you have to build a working id, parsing numbers to strings using .toString()
You really did write kind of messy code. What was supposed to result wasn't a list, it was various div-containers wrapped inside a ul-tag. Oh my.
BTW: Never ever check if sth. is 0 using the ==-operator. Better always use the ===-operator. Read about the problem here
BTW++: I don't know what value you wanted to read in your itemClicked()-function. I didn't test if it would read the innerHTML but generally, you can only read information from where information was written to before. In this sample, value should be empty i guess..
Hope i didn't forget about anything. The Code works right now as you can see. If you've got any further questions, just ask.
Cheers!
You can pass only the var i and search the id after like this:
Your p constructor dymanic with passing only i
<p id = "listNum' + i + '" onclick = itemclicked(' + i + ')>
function
function itemclicked(id)
{
id='listNum'+i;
alert("clicked at :"+id);
var pElement = document.getElementById(id).value;
alert("value of this is: "+pElement);
}
is what you want?
I am not sure but shouldn't the onclick function be wrapped with double quotes like so:
You have this
onclick = itemclicked(id)>'
And it should be this
onclick = "itemclicked(id)">'
You have to modify your itemclicked function to retrieve the "value" of your p element.
function itemclicked( id ) {
alert( "clicked at :" + id );
var el = document.getElementById( id );
// depending on the browser one of these will work
var pElement = el.contentText || el.innerText;
alert( "value of this is: " + pElement );
}

feel like im coming here way too often to ask questions but yet again I am stuck. I am attempting to select a textarea and allow myself to edit the text in another textarea, which works fine using textboxs but not with textareas. Every time I click on the div container I am getting an undefined result when looking for the textarea. Below is the code.
jQuery
$(".textAreaContainer").live('click','div', function(){
var divID = this.id;
if ( divID !== "" ){
var lastChar = divID.substr(divID.length - 1);
var t = $('#' + divID ).find(':input');
alert(t.attr('id'));
t = t.clone(false);
t.attr('data-related-field-id', t.attr('id'));
t.attr('id', t.attr('id') + '_Add');
t.attr('data-add-field', 'true');
var text = document.getElementById(divID).innerHTML;
//var textboxId = $('div.textAreaContainer').find('input[type="textArea"]')[lastChar].id;
$('div#placeholder input[type="button"]').hide();
var text = "<p>Please fill out what " + t.attr('id') +" Textarea shall contain</p>";
if ( $('#' + t.attr('id')).length == 0 ) {
$('div#placeholder').html(t);
$('div#placeholder').prepend(text);
}
}
else{
}
});
t.attr('id') should be returning textbox1(or similar) but instead just returns undefined.
I have tried .find(':textarea'),.find('textarea'),.find(text,textArea),.find(':input') and quite a few others that I have found through google but all of them return undefined and I have no idea why. A demo can be found here, http://jsfiddle.net/xYwaw/. Thanks in advance for any help guys, it is appreciated.
EDIT: Below is the code for a very similar example I am using. This does what I want to do but with textboxs instead of textareas.
$('#textAdd').live('click',function() {
var newdiv = document.createElement('div');
newdiv.innerHTML = "Textbox " + textBoxCounter + " <br><div id='container" + counter + "' class='container'><li><input type='text' id='textBox" + textBoxCounter +"' name='textBox" + textBoxCounter + "'></li></div></br>";
document.getElementById("identifier").appendChild(newdiv);
textBoxCounter++
counter++;
});
$(".container").live('click','div', function(){
var divID = this.id;
if ( divID !== "" ){
var lastChar = divID.substr(divID.length - 1);
var t = $('#' + divID).find('input');
alert(divID);
t = t.clone(false);
t.attr('data-related-field-id', t.attr('id'));
alert(t.attr('id'));
t.attr('id', t.attr('id') + '_Add');
t.attr('data-add-field', 'true');
var text = document.getElementById(divID).innerHTML;
// var textboxId = $('div.container').find('input[type="text"]')[lastChar].id;
$('div#placeholder input[type="button"]').hide();
var text = "<p>Please fill out what " + t.attr('id') +" textbox shall contain</p>";
if ( $('#' + t.attr('id')).length == 0 ) {
$('div#placeholder').html(t);
$('div#placeholder').prepend(text);
}
}
else{
}
});
First up remove the second parameter, 'div', from the first line:
$(".textAreaContainer").live('click','div', function(){
...to make it:
$(".textAreaContainer").live('click', function(){
Then change:
var t = $('#' + divID ).find(':input');
...to:
var t = $(this).find(':input');
Because you already know that this is the container so there's no need to select it again by id. Also the id attributes that you're assigning to your textarea containers have a space in them, which is invalid and results in your original code trying to select the element with '#textAreaContainer 0' which actually looks for a 0 tag that is a descendant of #textAreaContainer. So fixing the code that creates the elements to remove that space in the id is both a good idea in general and an alternative way of fixing this problem.
