Select html content from an element

Select html content from an element - javascript

I would like to select the content of this element
<div class="entry-content">
comment.body +
</div>
I want to get that comment.body in the function I call below, more precisely in
var body = parent.find('entry-content');
How can I select the content of a certain div? I tried val() and contents() and none of them worked.
Any suggestion?
$("body").on("click", ".show-textarea", function(){
var answerid = $(this).data('answer');
var type = $(this).data('type');
var questionid = $(this).data('question');
var $commentForm = $(this).parent().find('.comment-form').first();
console.log(answerid);
$.getJSON("/controller/api/comments/comment.php", {
answerid : answerid,
questionid : questionid,
type : type
}, function (data) {
$commentForm.find('article').remove();
console.log("AID " + answerid);
console.log("Data" + data.length);
$.each(data, function(i, comment) {
console.log("Comment:" + comment);
$commentForm.append('<article class="tweet-data">' +
'<div class="comment-items">' +
'<div class="qa-c-list-item hentry comment" id="c3574">' +
'<div class="asker-avatar">' +
'<a>' +
'<img width="40" height="40" src="' +

'<div class="qa-c-wrap">' +
'<div class="post-button">' +
'<button name="" onclick="" class="btn icon-flag" title="Flag this comment as spam or inappropriate" type="submit">flag</button>' +
'<button name="" class="btn icon-answers" title="Reply to this comment" type="submit">reply</button>' +
'</div>' +
'<span class="qa-c-item-meta">' +
'commented' +
' 1 day' +

'</span> ' +
'</span> ' +
'</span> ' +
'<div class="qa-c-item-content" style="color: #2d2727; font-size: 13px"> ' +
'<a name="3574"></a>' +
'<div class="entry-content">' +

'</div> ' +
'</div> ' +
'<div class="comment-edit-form">' +
'<form method="post" action="/controller/actions/comments/edit_comment.php">' +
'<button class = "edit-comment btn {if !$isMine}hidden{/if}" type="button">Edit</button>' +
'</form>' +
'</div> ' +
'</div> <!-- END qa-c-item --> ' +
'</div>' +
'</div></article>');
});
});
$commentForm.show();
});
$("body").on("click", ".textarea-ok, .textarea-cancel", function(){
commentsFetched = false;
$('.comment-form').hide();
});
$("body").on("click", ".edit-comment", function(){
console.log("Hello");
var parent = $("body").find('article').last();
var body = parent.find('entry-content');
console.log(body);
var parent_parent = $("body").find('article').parent().last();
parent.remove();
console.log(parent);
var button = $(this),
commentField = $('<div class="comment-form">' +
'<form method="post" action="/controller/actions/comments/edit_comment.php">' +
'<textarea name="comment" rows="4" cols="40" class="qa-form-tall-text">' +
body +
'</textarea>' +
'<input type="hidden" name="answerid" value="" />' +
'<input type="hidden" name="questionid" value="" />' +
'<button type="submit" class="textarea-ok">Edit Comment</button>' +
'</form>' +
'</div>'); // create a textarea element
commentField
// set the textarea's value to be the saved content, or a default if there is no saved content
.val(button.data('textContent') || 'This is my comment field\'s text')
// set up a keypress handler on the textarea
.keypress(function(e) {
if (e.which === 13) { // if it's the enter button
e.preventDefault(); // ignore the line break
button.data('textContent', this.value); // save the content to the button
$(this).remove(); // remove the textarea
}
}).appendTo(parent_parent); // add the textarea to the document
});

Since the binding is on '.edit-comment' which is a child of the '.tweet-data' encapsulating each individual entry (from the looks of your logic) I would suggest doing
$(this).closest('.tweet-data').find('.entry-content').text();
Your current logic is going to the last article for the 'parent' element. So if you tried to click the edit comment option on a tweet data other than the last one, your logic will most likely not work. Doing the lookup contextually by which element was clicked will fix this potential issue.

So when I click the add button, I clone the that contains tomselect input, but the tom-select input in the cloned tr doesnt work... How can I use tom-select input dynamically?? here's my code..

How can I use tomselect dynamically or initialize when I click the add button?? thanks

I tried to clone the wrong object... I made a temporary tr object and clone it... and It works

Dynamically created button gets automatically fired

I am creating a dynamic unordered custom List view. In each element, there is one button. I am creating the list elements in the following way:
for (i = 0; i < arrayID.length; i++) {
var listElement = '<li class="has-form">' +
'<div class="row collapse">' +
'<div class="small-1 columns" style="margin: 5px">' +
'<img src="image/twitter.png">' +
'</div>' +
'<div class="small-6 columns small-only-text-center">' +
'<p>' +
'<i>' + arrayText[i] + '</i>' +
'</p>' +
'</div>' +
'<div class="small-3 columns">' +
'<button type="button" class="large-10" onclick="' + onClickViewButton() + '">view</button>' +
'</div>' +
'<div class="small-1 columns">' +
'<input id="checkbox1" type="checkbox">' +
'</div>' +
'</div>' +
'</li>';
$("#myList").append(listElement);
}
The code for button click is:
function onClickViewButton() {
alert('hello');
}
But unfortunately the when the page is loading, the button click is fired and not working on actual button click.
Please help.

Where you have:
onclick="'+onClickViewButton()+'"
you need to have:
onclick="onClickViewButton()"
instead.
Your current code calls the onClickViewButton function in your declaration, when what you really want to do is to just use it as a function reference so it gets called later on onclick.

Try with this snippet:
If you concat function name with parenthesis then it will be treated as function execution hence function will get called.
for (i = 0; i < arrayID.length; i++) {
var listElement = '<li class="has-form">' +
'<div class="row collapse">' +
'<div class="small-1 columns" style="margin: 5px">' +
'<img src="image/twitter.png">' +
'</div>' +
'<div class="small-6 columns small-only-text-center">' +
'<p>' +
'<i>' + arrayText[i] + '</i>' +
'</p>' +
'</div>' +
'<div class="small-3 columns">' +
'<button type="button" class="large-10" onclick="onClickViewButton()">view</button>' +
'</div>' +
'<div class="small-1 columns">' +
'<input id="checkbox1" type="checkbox">' +
'</div>' +
'</div>' +
'</li>';
$("#myList").append(listElement);
}

Better way to use html templete with json response

I am getting json response from my server.
I am getting detail of user like school(name,id),major subject(name,id),start ,end etc.
I want to show this is appropriate text fields inside a form where user can edit this and after editing user should submit it again to server.
I am embadding fetched json code with html code inside the jquery.
I am finding it very difficult to manage html inside jquery is there any better way to this with following code.
$(document).on('click', '.edit-edu', function(event) {
event.preventDefault();
var id = $(this).parents('.row').attr('id');
var id1 = id.split('-');
$.post("SingleEdu", {id: id1[1]}, function(data) {
console.log(data);
$.each(data.educationList, function(key, value) {
$('#' + id).replaceWith('<div id="addNewEdu" class="addorEdit">'

+ '<input type="hidden" name="ed.pageBySchoolPid.id" value="' + value.pageBySchoolPid.id + '" id="schoolId2" label="School/College" cssClass="form-control">'

+ '<input type="text" name="ed.start" value="' + value.start + '" id="sstart1" label="From" placeholder="eg. Start: July 2007" cssClass="form-control">'
+ '</div>'
+ '</div>'
+ '<div class="form-group">'
+ '<div class="col-md-2">'
+ '<label>End</label>'
+ '</div>'
+ '<div class="col-md-6">'
+ '<input type="text" name="ed.end" value="' + value.end + '" id="send1" label="To" placeholder="eg. End : May 2011 or Till" cssClass="form-control">'
+ '</div>'
+ '</div>'
+ '<div class="form-group">'

+ ' </div>'
+ '<div class="col-md-6">'

<div>School</div>
<div>start end</div>
<i class="fa fa-edit edit-edu">edit</i>
<i class="fa fa-times delete-edu"></i>
</div>

You could store your code inside another .html file and pull it in using another AJAX call:
var FormHTML = '';
$.get('form.html', function(data) {
FormHTML = data;
});
Then to get your values in you can set up your input HTML with something that can be easily replaced out. I've just wrapped the object name in between some #:
<input type="hidden" name="ed.pageByMajorPid.id" value="##pageByMajorPid.id##" id="majorId1" label="Class" cssClass="form-control">
Then to replace out these values with your actual values, just do a loop:
for (var name in value) {
if (typeof value[name] != 'object') { // If not an object, replace the value
formHTML = formHTML.replace('##' + name + '##', value[name])
} else { // Else if it is an object, loop through it
for (var name2 in value[name]) {
formHTML = formHTML.replace('##' + name + '.' + name2 + '##', value[name][name2])
}
}
}
$('#' + id).replaceWith(formHTML);
Hope that works for you, let me know :)

You can use template engine like Mustache https://mustache.github.io/

Updating two dynamic text fields simultaneously

See below code. I am creating 2 text fields at a time. Now how could I type on one text field and make the other twin text field have the same values simultaneously?
<button type="button" id="tfButton">Add text</button>
<div id="InputsWrapper"></div>
<div id="OuterWrapper"></div>
<script>
$(document).ready(function() {
var tfCont = 0;
var InputsWrapper = $("#InputsWrapper");
var x = InputsWrapper.length;
var namefield = $("#tfButton");
$(namefield).click(function() {
tfCont++;
$(InputsWrapper).append('<div>' + '<div class="name" id="InputsWrapper_0' + tfCont + '">' + '<input type="textarea" id="field_' + tfCont + '" class="fTypex" placeholder="Thought of the day..."/>' + '<br>' + '</div>' + '</div>');
$(OuterWrapper).append('<div id="textLayer_' + tfCont + '">' + '<input type="textarea" id="tf_' + tfCont + '">' + '</div>');
x++;
return false;
});
});
</script>

I created a fiddle that I think does what you want: http://jsfiddle.net/3h1h5j7y/
Here is the code.
HTML
<button type="button" id="tfButton">Add text</button>
<div id="InputsWrapper"></div>
<div id="OuterWrapper"></div>
JavaScript
I added a data- attribute to the inputs with the tfCont id so that they can operate in pairs as they are added.
Also, I am using the on() method so that objects can be added dynamically. It is filtering on the fTypex class.
$(document).ready(function() {
var tfCont = 0;
var InputsWrapper = $("#InputsWrapper");
var x = InputsWrapper.length;
var namefield = $("#tfButton");
$(namefield).click(function() {
tfCont++;
$(InputsWrapper).append('<div>' + '<div class="name" id="InputsWrapper_0' + tfCont + '">' + '<input type="textarea" id="field_' + tfCont + '" class="fTypex" placeholder="Thought of the day..." data-tfcount="' + tfCont + '"/>' + '<br>' + '</div>' + '</div>');
$("#OuterWrapper").append('<div id="textLayer_' + tfCont + '">' + '<input type="textarea" id="tf_' + tfCont + '" data-tfcount="' + tfCont + '">' + '</div>');
x++;
return false;
});
$(document).on("click blur keyup", "input.fTypex", function() {
var tfc = $(this).data("tfcount");
$("#tf_" + tfc).val(this.value);
});
});
I had to change $(OuterWrapper) from your example to $("#OuterWrapper") because there was not a variable.

Try something like this :
use onkeyup to call a function which binds the values
HTML
<body>
<input id='ip1' onkeyup='updateOther(this);' type='text'>
<input id='ip2' type='text'>
<script src="script.js"></script>
</body>
JS:
function updateOther(obj){
$('#ip2').val($(obj).val()) ;
}

Dynamic Pictures are Not Showing up

I have list of restaurants and I have to append pictures of each restaurant, which is coming from a database. For this I made div's id dynamic but the pictures not append on that div. If I make the div's id static then it shows the picture coming from the server. The problem is with making the div id dynamic. Please help me. Here is my sample code:
$("#list").empty();
$.each(data, function (i, item) {
if (data[i].has_logo == 1) {
$('#pic' + i).css("background-image", "url('http://www.thefoodhive.com/web_root/provider_uploads/" + data[i].id + "/logo.jpg')");
}
if (data[i].has_menu == 0) {
status = 'Call Now';
} else {
status = 'Order Now';
}
if (data[i].from_time == '' || data[i].from_time == null) {
data[i].from_time = 'NA';
data[i].to_time = '';
}
content = '<div ><div class="container"><div id="pic' + i + '" class="left"></div><div class="right"><div class="rightno">' + data[i].name + '</div></h4></p><i>Address:' + data[i].address + ',Timing:' + data[i].from_time + '-' + data[i].to_time + '</i><br><center><div style="float: right;"></div></div> <div class="bottom"><div class="btnleft" style="float: left;"><input class="callbttn" value="CALL NOW"type="button"></input></div><div class="btnright" style="float: left;"><input class="callbttn" value="' + status + '" type="button" onclick="getdata(\'' + data[i].id + '\',\'' + data[i].has_menu + '\',\'' + data[i].phone_no + '\');"></input></div></div>';

You are applying style to a div that doesn't exists yet...
Try to apply the background inline, like this:
content = '<div ><div class="container"><div id="pic' + i + '"
class="left" style="background-image:url(http://www.thefoodhive.com/web_root/provider_uploads/' + data[i].id + '/logo.jpg">...
