I'm developing a Question&Answer website in php and I want to print the answer comments when I press the button. Everything works like a charm but only on the first button. I have an idea why this does't work, I guess it only takes into account the first id that it finds.
So , my question is, is there any way to name the element I want to call based on its id? For example:
<button class="btn icon-chat" title="Add a comment on this answer"
type="button" id="showarea . {answer['answerid']"} name="showarea" value="Show Textarea">
Comment</button>
<div id="textarea">
{include file="comment_form.tpl"}
</div>
But how would I call this PHP variable on my JS function?
$("#textarea, #textarea-ok").hide(); // or you can have hidden w/ CSS
$("#showarea").click(function(){
$("#textarea").show();
});
$("#textarea-ok, #cancel").click(function(){
$("#textarea").hide();
});
Is this the best approach? Any advise regarding to the JS code you can give?
Kind Regards
Live method should be ok
$("body").on("click", ".myClass", function(){
// do it again // or #myId
});
Don't forget about an event with an Id selector can be only on one element, and class on every one...
Edit with example
<div class="post-button clearfix">
// i changed this button as well
<button class="btn icon-chat show-textarea" title="Add a comment on this answer" type="button" data-answer="{$answer['publicationid']}">Comment</button>
<div class="textarea">
{include file="comment_form.tpl"}
</div>
</div>
// comment_form.tpl
// i added a master container
<div class="comment-form">
<form method="post" action="{$BASE_URL}controller/actions/comments/create_comment.php">
<textarea name="comment" rows="4" cols="40" class="qa-form-tall-text"></textarea>
// i deleted the wrong input here
<input type="hidden" name="answerid" value="{$answer['answerid']}" />
<input type="hidden" name="questionid" value="{$question['publicationid']}" />
// i changed these 2 buttons as well
<button type="button" class="textarea-cancel qa-form-tall-button qa-form-tall-button-comment">Cancel</button>
<button type="submit" class="textarea-ok">Ok</button>
</form>
</div>
Then you change the script with class in selector like :
...
$('.comment-form').hide();
$("body").on("click", ".show-textarea", function(){
$('.comment-form').show();
});
$("body").on("click", ".textarea-ok, .textarea-cancel", function(){
$('.comment-form').hide();
});
....

I'm new to coding and need to create HTML text in an HTML form on a page and open up the text in a Javascript alert box. I've tried various code to no success. Here is what I've come up with so far which does not create a pop up alert box:
Here is the HTML and the JS:
Function myfunction1()
{
Let myfun1 = document.getElementById('sec1-input').value;
Alert(myfun1);
}
<div class="form-group">
<label for="sec1-input"><strong>Enter Alert Text: </strong></label>
<input type="text" class="form-control" id="sec1-input">
</div>
<button id="sec1-btn1" type="button" class="btn btn-primary">Alert Me!</button>
I'm not sure what do you want, but I'll show you how to make an alert window exactly as you're asking.
First of all you must consider several mistakes that you are making. JavaScript does not recognize the word Function because it is capitalized. The function keyword must be lowercase.
Here I leave you a referring link with JavaScript reserved words: https://www.w3schools.com/js/js_reserved.asp
On the other hand, I see that you are not using the form tag, which leads to two problems: technical and semantic. Here I leave you another link with reference to forms: https://www.w3schools.com/html/html_forms.asp
Finally, to achieve what you want you need to work with events, especially with the click event. Here I will leave you a reference link and the solution you want:
let button = document.querySelector('#sec1-btn1');
button.addEventListener('click', function(e) {
let val = document.querySelector('#sec1-input').value;
alert(val);
});
<form>
<div class="form-group">
<label for="sec1-input"><strong>Enter Alert Text: </strong></label>
<input type="text" class="form-control" id="sec1-input" />
</div>
<button id="sec1-btn1" type="button" class="btn btn-primary">
Alert Me!
</button>
</form>
You have not called the function anywhere. For it to work you need to use a listener.
<div class="form-group">
<label for="sec1-input"><strong>Enter Alert Text: </strong></label>
<input type="text" class="form-control" id="sec1-input">
</div>
<button onclick="myfunction1()" id="sec1-btn1" type="button" class="btn btn-primary">Alert Me!</button>
<script>
function myfunction1() {
let myfun1 = document.getElementById('sec1-input').value;
alert(myfun1)
}
</script>
I added the onClick listener to button and now it works.
javaScript is case sensitive
function myfunction1()
{
let myfun1 = document.getElementById('sec1-input').value;
alert(myfun1);
}
<div class="form-group">
<label for="sec1-label"><strong>Enter Alert Text: </strong></label>
<input type="text" class="form-control" id="sec1-input">
</div>
<button id="sec1-btn1" type="button" onClick="myfunction1()" class="btn btn-primary">Alert Me!</button>
also IDs of elements should not be the same , to assign same selector , use class and you also need to give your function to your element's event listener
You should not start javascript functions like alert with capital letters.
Put this piece of code instead of your button:
<button id="sec1-btn1" type="button" class="btn btn-primary" onclick="myfunction1()">Alert Me!</button>
I'm working on a form with 5 divs and to keep the form as clean and tidy as possible, I kept 4 of them hidden with "display: none".
When the button (ex. Add Client) is clicked, I want the next div (up to 4 more) to be displayed with a js, and when the other button (ex. Remove Client) is clicked, I want the last displayed div to be hidden again.
JS:
<script>
$(document).ready(function addClient() {/*mycode*/});
$(document).ready(function removeClient() {/*mycode*/});
</script>
HTML:
<input id="kkBtnNewClient" type="button" value="New Client" class="kkButton" onclick="addClient()"/>
<input id="kkBtnRemoveClient" type="button" value="Remove Client" class="kkButton" onclick="removeClient()"/>
I tried to put a simple alert in the /mycode/ part, but I don't even get to that part.
The value you pass to ready() is called when the ready event fires.
It does not create a global variable from which to call the function.
Use a function declaration to do that. Better yet, bind the event handler with JavaScript and don't use onclick attributes at all.
$("#kkBtnNewClient").on("click", function addClient() {
alert("add client");
});
$("#kkBtnRemoveClient").on("click", function removeClient() {
alert("remove client");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="kkBtnNewClient" type="button" value="New Client" class="kkButton" />
<input id="kkBtnRemoveClient" type="button" value="Remove Client" class="kkButton" />
You may try like as below:
$(".group_1").hide();
$(".group_2").hide();
$(document).on('click','#kkBtnNewClient', function(){
console.log("kkBtnNewClient clicked");
$(".group_1").show();
$(".group_2").hide();
});
$(document).on('click','#kkBtnRemoveClient', function(){
$(".group_2").show();
$(".group_1").hide();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="group_1">
div 1
</div>
<div class="group_1">
div 2
</div>
<div class="group_1">
div 3
</div>
<div class="group_1">
div 4
</div>
<div class="group_2">
div 5
</div>
<input id="kkBtnNewClient" type="button" value="New Client" class="kkButton" />
<input id="kkBtnRemoveClient" type="button" value="Remove Client" class="kkButton" />
I have created a popup which allows users to edit a value then they can submit it again
Html:
<body>
<input id="submit" type="submit" value="Submit" data-theme="b" data-icon="check" data-rel="popup"/>
<div id="success" data-role="popup">
</div>
<div id="fail" data-role="popup">
<p>Fail</p>
</div>
</body>
jQuery:
$('#submit').click(function(){
var doStuff = true;
if(doStuff === true){
$("#success").empty();
$("#success").append('<p> <input type="text" value="' + doStuff + '" /> <input type="submit" id="popupConfirm" value="Submit" /> </p>');
$("#success").popup("open");
}else{
$("#fail").popup("open");
}
});
$('#popupConfirm').click(function(){
console.log("jhasgd");
});
Currently the click is not working at all that's why I have gibberish in the console.log and also I am not sure how to get the value of the entered input.
So my question is first how can I get the submit click to work and then output what they wrote?
fiddle of the code
$(document).on('click', '#popupConfirm', function(){
console.log("jhasgd");
});
Where are you adding the jQuery code at? If you are adding it all above the HTML, it might be trying to bind the #submit input before it exists in the DOM. Can you try to wrap the code in a document ready so it won't do the click binding before the DOM gets filled up.
$( document ).ready(function()
{
$('#submit').click(function(){
console.log("clicked the button");
});
});
Edit: I just saw the comment where you figured this out above. You didn't really have a code solution provided, so I will just leave this as is.
i have this html form
<form action="" method="post" name="login_form">
Email : <input type="text" id="email2" name="email" /><br />
<span id="passwordT" >Password : </span>
<input type="password" name="password" id="password2"/><br />
<input type="button" id="submit_botton" value="Login" />
<div><input id="forgot" type="button" value="Forgot your Password?" /></div>
</form>
and the javascript here
var forgot = $('#forgot');
var forgot2 = $('#forgot2');
forgot.click(function() {
$('#password2').hide();
$('span#passwordT').hide();
$('input#submit_botton').prop('value', 'Reset Passowrd');
$('input#forgot').replaceWith('<input id="forgot2" type="button" value="Login here" />');
});
$('input#forgot2').click(function() { // this function didnt want to work
$('input#forgot2').prop('value', 'Forgot your Password?');
$('#password2').show();
$('span#passwordT').show();
$('input#submit_botton').prop('value', 'Login');
});
HERE JS-DEMO
what i want is :
when i click on second function i will get back the buttons as they were in first time.
I tried to make this second function inside the first but what i got is the function works but only one time , i mean if i click again to reset password will not work.
thanks for the help.
Your problem is that you're trying to attach an event handler to an element that doesn't exist yet. That's not possible with direct event handlers. Use delegated events instead.
$(document).on('click','#forgot2', function(){ ... });
document can be replaced with any #forgot2 container that exists at binding time.
As a side note, take into account that when you use selectors by id (e.g #forgot2) it's not necessary to add anything else since an id identify one and just one element (repeated ids are not allowed). So this selector input#forgot2 is not wrong but more complex than necessary.
<script type="text/javascript">
$('#did').html('<input type="submit" name="mybtn" value="Save" onClick="saveContent('+valA+')">');
function saveContent(con){
alert (con);
}
</script>
I am using this code to display a submit button and it comes to the page body. but when clicked on the button it is not alerting the value. Please help me...
Thanks
Why type="submit"?
assuming #did is the id of your div or some container
$("#did").html($("<input type='button' value='save' />").click(function(){
alert(valA);
}));
This will append a button in your div with click event attached to it. Remember type should be button for this case.
Escape insert variable
Your result is:
<input type="submit" name="mybtn" value="Save" onClick="saveContent(sometext)">
Error : sometext is not defined
$('#did').html('<input type="submit" name="mybtn" value="Save" onClick="saveContent(\''+valA+'\')">');
function saveContent(con){
alert (con);
}
Result of this:
<input type="submit" name="mybtn" value="Save" onClick="saveContent('sometext')">
