I have the following php while loop code:
while (...($...)){
$convid = $row['ID'];
echo"
<button onclick='getconvo($convid)'>open</button>
<div class="convowrap"></div>
";
}
and the javascript code
<script type='text/javascript'>
$(document).ready(function(){
$(".convowrap").hide(0)
})
</script>
script type='text/javascript'>
function getconvo(id){
$(".convowrap").hide(0).delay(200).slideDown(500)
var convid = id;
$('.convowrap').load('fetch_info.php', {id : convid}, function () {
// do something when success
});
}
</script>
When i click on the button above that says 'open,' all of the div that says convowrap slides, but i only want the current div to slide based on the button that was clicked that was generated from the php while loop.
If the php loop executed three times, when i click on the first button generated by the first loop, the convowrap div slides on all three entries generated by the loop.
What do I do? Please help?
Thanks in advance.
The problem is that all the divs have the same class so its functioning as you it is supposed to ...
As you have the div after the button you can replace
$(".convowrap")
With
$(this).next()
Inside the function for both .load and .hide
(Whichever you want)
more generic
It may be more usefull to assign another class to each div like
<div class='convowrap dummyclass$convid'></div>
And on button click change the selector to match that class like
$('dummyclass'+id)
Hope this helps
As you are using inline onlclick function inside HTML, you have to pass this explicitly like onclick='getconvo(this)'.
Anyway, see the following fiddle and hope you wanted this workaround -
https://jsfiddle.net/nuhil/4scas2gh/
Code:
<button onclick='getconvo(this)' id="1">Button 1</button>
<div class="convowrap">Content First</div>
<br/>
<button onclick='getconvo(this)' id="2">Button 2</button>
<div class="convowrap">Content Second</div>
<!-- More pairs of (button and div) go here -->
<script>
$(document).ready(function(){
$(".convowrap").hide();
})
function getconvo(button){
$(button).next().delay(200).slideDown(500);
// You could use toggle here like following for better UX
// $(button).next().toggle("slow");
// Anyway,
// Get the id from button attribute but make sure you already set it by PHP
var convid = $(button).attr("id");
console.log(convid);
// $(button).next().load('fetch_info.php', {id : convid}, function () {
// do something when success
// });
}
</script>

I have a script that gets data from a Google Sheet and displays it as a webpage - using JS and Tabletop.js.
There are multiple entries in the Sheet thus multiple entries in the webpage. To organise the Data I have a hide/show button. When the button is clicked on the first entry it works. However when the any of the other buttons are clicked it hides or shows the first entries data, not its own!
How do I hide/show each individual entries data? Below is the code I am working with!
I am new to JavaScript - Thanks in advance!
P.S - I struggled writing the Title to the questions!

Are all the entries on your page filled from the given template, meaning they are divs with the class entry? If so, I think your issue is the following: Your entry div has a child div with the id="add-info". And when you click the button, your handler function (myFunction()) tries to get a reference to that div via document.getElementById("add-info"); Now, if you have multiple such entries on a page, you will have multiple divs with id="add-info". But the id attribute of an element must be unique in your whole document. See the description of id or that of getElementById().
So the root cause of your problem is that the same id is used multiple times in the document when it shouldn't be. You get the behavior you're seeing because getElementById() just happens to be returning a reference to the first element it finds on the page, regardless of which button you click. But I believe you're in undefined behavior territory at that point.
One way to solve the problem is to somehow give myFunction() information about which button was clicked, while making each div you'd like to manipulate unique so they can be found easier. For instance, you can use the order of the restaurant on your page as its "index", and use that as the id of the div you'd like to hide/show. And you can also pass this index as an argument when you call your click handler:
...
<button id="btn" class="button-primary" onclick="myFunction('{{index}}')">Hide</button>
<div id="{{index}}">
<!-- The rest of the code here... -->
...
... add the index into your template context, so Handlebars can fill in the {{index}} placeholder:
...
$.each( tabletop.sheets("food").all(), function(i, food) {
food.index = i // Give your context its 'index'
var html = template(food);
$("#content").append(html);
});
...
... and then alter your function slightly to use the given argument instead of always looking for the div with id="add-info":
function myFunction(indexToToggle) {
var x = document.getElementById(indexToToggle);
// rest of the code is same
With this approach, I expect your DOM to end up with divs that have ids that are just numbers ("3", "4", etc.) and your click handler should get called with those as arguments as well.
Also note that your <button> element has id="btn". If you repeat that template on your page, you will have multiple <button>s with the same id. If you start trying to get references to your buttons via id you will have similar issues with them too since the ids won't be unique.
I'm trying to make a text editable on clicking it. Below is the code I'm trying. When the title is clicked it shows an input box and button to save it.
<div class="block">
<div class="title">Title</div>
<div class="title-edit">
<input type="text" name="title" value="Title">
<button>Save</button>
</div>
</div>
I have changed other properties like color or changing the text of the elements and its working, but it is not applying the display property or .show()/.hide() function on the title or edit elements.
Below is my jQuery
$(function(){
$('.block').on('click', editTitle);
$('.title-edit button').on('click', saveTitle);
});
function saveTitle(){
var parent = $(this).closest('.block');
var title = $('.title', parent);
var edit = $('.title-edit', parent);
$(title).show();
$(edit).hide();
}
function editTitle(){
$('.title-edit', this).show();
$('.title', this).hide();
}
Here's the jsfiddle
https://jsfiddle.net/ywezpag7/
I've added
$(title).html('abcd');
to the end to show that other properties/functions are working, but just not the display.
For checking the html change on title element you will have to check the source through developer tools cause the title element is hidden.
Where am I going wrong?
Your problem is in the function saveTitle. The first line must stop the event propagation otherwise after this function the editTitle function is called.
The snippet:
$(function(){
$('.block').on('click', editTitle);
$('.title-edit button').on('click', saveTitle);
});
function saveTitle(e){
// this line
e.stopPropagation();
var parent = $(this).closest('.block');
var title = $('.title', parent);
var edit = $('.title-edit', parent);
title.show();
edit.hide();
title.text($('.title-edit input').val());
}
function editTitle(e){
$('.title-edit', this).show();
$('.title', this).hide();
}
.title-edit{
display:none
}
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<div class="block">
<div class="title">Title</div>
<div class="title-edit">
<input type="text" name="title" value="Title">
<button>Save</button>
</div>
</div>
The issue as mentioned already is that your click events are fighting. In your code, the title-edit class is within the block, so when you click on the save button it triggers events for both clicks.
The easiest and, imho, cleanest way to resolve this is to switch your click event to be called on .title, and .title-edit button. You can also simplify the code beyond what you've got there.
$(function(){
$('.title').click(editTitle);
$('.title-edit button').click(saveTitle);
});
function saveTitle(){
$('.title').show();
$('.title-edit').hide();
$(title).html('abcd');
}
function editTitle(){
$('.title-edit').show();
$('.title').hide();
}

I tried debug your code, and I had seen, that then you click to "Save" button, handled both functions, saveTitle() and editTitle(), and in that order. Therefore, the elements initially hidden, and then shown.
I've created a function that works great but it causes me to have a lot more messy html code where I have to initialize it. I would like to see if I can make it more generic where when an object is clicked, the javascript/jquery grabs the href and executes the rest of the function without the need for a unique ID on each object that's clicked.
code that works currently:
<script type="text/javascript">
function linkPrepend(element){
var divelement = document.getElementById(element);
var href=$(divelement).attr('href');
$.get(href,function (hdisplayed) {
$("#content").empty()
.prepend(hdisplayed);
});
}
</script>
html:
<button id="test1" href="page1.html" onclick="linkPrepend('test1')">testButton1</button>
<button id="test2" href="page2.html" onclick="linkPrepend('test2')">testButton1</button>
<!-- when clicking the button, it fills the div 'content' with the URL's html -->
<div id="content"></div>
I'd like to end up having html that looks something like this:
<button href="page1.html" onclick="linkPrepend()">testButton1</button>
<button href="page2.html" onclick="linkPrepend()">testButton1</button>
<!-- when clicking the button, it fills the div 'content' with the URL's html -->
<div id="content"></div>
If there is even a simpler way of doing it please do tell. Maybe there could be a more generic way where the javascript/jquery is using an event handler and listening for a click request? Then I wouldn't even need a onclick html markup?
I would prefer if we could use pure jquery if possible.
I would suggest setting up the click event in JavaScript (during onload or onready) instead of in your markup. Put a common class on the buttons you want to apply this click event to. For example:
<button class="prepend-btn" href="page2.html">testButton1</button>
<script>
$(document).ready(function() {
//Specify click event handler for every element containing the ".prepend-btn" class
$(".prepend-btn").click(function() {
var href = $(this).attr('href'); //this references the element that was clicked
$.get(href, function (hdisplayed) {
$("#content").empty().prepend(hdisplayed);
});
});
});
</script>
You can pass this instead of an ID.
<button data-href="page2.html" onclick="linkPrepend(this)">testButton1</button>
and then use
function linkPrepend(element) {
var href = $(this).data('href');
$.get(href, function (hdisplayed) {
$("#content").empty().prepend(hdisplayed);
});
}
NOTE: You might have noticed that I changed href to data-href. This is because href is an invalid attribute for button so you should be using the HTML 5 data-* attributes.
But if you are using jQuery you should leave aside inline click handlers and use the jQuery handlers
<button data-href="page2.html">testButton1</button>
$(function () {
$('#someparent button').click(function () {
var href = $(this).data('href');
$.get(href, function (hdisplayed) {
$("#content").empty().prepend(hdisplayed);
});
});
});
$('#someparent button') here you can use CSS selectors to find the right buttons, or you can append an extra class to them.
href is not a valid attribute for the button element. You can instead use the data attribute to store custom properties. Your markup could then look like this
<button data-href="page1.html">Test Button 1</button>
<button data-href="page2.html">Test Button 1</button>
<div id="content">
</div>
From there you can use the Has Attribute selector to get all the buttons that have the data-href attribute. jQuery has a function called .load() that will get content and load it into a target for you. So your script will look like
$('button[data-href]').on('click',function(){
$('#content').load($(this).data('href'));
});
looking over the other responses this kinda combines them.
<button data-href="page2.html" class="show">testButton1</button>
<li data-href="page1.html" class="show"></li>
class gives you ability to put this specific javascript function on whatever you choose.
$(".show").click( function(){
var href = $(this).attr("data-href");
$.get(href,function (hdisplayed) {
$("#content").html( hdisplayed );
});
});
This is easily accomplished with some jQuery:
$("button.prepend").click( function(){
var href = $(this).attr("href");
$.get(href,function (hdisplayed) {
$("#content").html( hdisplayed );
});
});
And small HTML modifications (adding prepend class):
<button href="page1.html" class="prepend">testButton1</button>
<button href="page2.html" class="prepend">testButton2</button>
<div id="content"></div>
HTML code
<button href="page1.html" class="showContent">testButton1</button>
<button href="page2.html"class="showContent">testButton1</button>
<!-- when clicking the button, it fills the div 'content' with the URL's html -->
<div id="content"></div>
JS code
<script type="text/javascript">
$('.showContent').click(function(){
var $this = $(this),
$href = $this.attr('href');
$.get($href,function (hdisplayed) {
$("#content").empty().prepend(hdisplayed);
});
}
});
</script>
Hope it helps.
I want to remove class of div id from other page anchor link.
firstPage.html
<div class="question show" id="a1">
Sample 1
</div>
<div class="question" id="a2">
Sample 2
</div>
list.html
$(function () {
$("a").click(function () {
$("#a2").addClass('question show');
});
});
</script>
</head>
<body>
Link 1
Link 2
</body>
I want to add class addClass('question show') to that div id which is clicked.
I tried here with Link1 for id=a1
But I'm failed to set class ('question show') help me to correct my code
Please check code here
http://plnkr.co/edit/fzdfjdrRbcWmir5wHcJW?p=preview
I'm taking a different approach. I'll not add the function to list.html. Let the page firstPage.html be called with the value. We will capture the anchor from firstPage.html.
Also, since your all divs have the class 'question'; I'm ignoring that class and targeting only 'show' class.
So, load this function with your firstPage.html:
$(document).ready(function(){
var call = $(location).attr('href').split('#');
var ancr = $.trim(call[1]);
if(ancr === undefined || ancr == ''){
// Anchor not set, do nothing
} else {
if (!$('#'+ancr).hasClass('show')) {
$('#'+ancr).addClass('show');
}
}
});
I also assume you don't have multiple divs with same ID (which generally should not be).
I hope this will do what you need.
How do i load a test.html multiple time using jQuery.
function loadScreen()
{
$('#result').load('test.html');
}
main.html
<div id='result'></div>
<input type="button" value="click me" onclick="loadScreen()">
test.html
<body>
<p>
testing
</p>
</body>
Current situation
when i click the button click me. it will load once
show on main.html
testing
what i want to do
How can i do it when i click the button twice
it will show
testing
testing
and with different div id
1st time button click show testing <div id="result1">testing</div>
2nd time button click show testing <div id="result2">testing</div>
it will append incremental 1 at id.
load() will replace the content of the target element which is why it's not working as you want.
Try this instead:
function loadScreen() {
var divId = $("#result > div").length + 1;
$('#result').append("<div></div>").attr("id", "result" + divId).load('test.html');
}
Then it's about time you should use $.get(), then create a div via the $(), add in the contents using .html() and .appendTo() the results div.
var result = $('#result'), //cache result box
i = 0;
function loadScreen(){
$.get('test.html',function(data){ //initiate get
$('<div>',{ //create div for return data
id : 'result'+(++i) //add attributes
})
.html(data) //add data
.appendTo(result); //append to result
});
}
