I want to pass the value of the limit in Jquery at the touch of a button. I almost found a solution, but can not quite understand. How to set the value to "limit:" the default and change it by pressing the button.
HTML
<button id="pagelimit default">1</button>
<button id="pagelimit">2</button>
<button id="pagelimit">3</button>
</div>
JS
function displayVals() {
var pagelim = $( "#pagelimit" ).val();
};
$('#product-grid').mixItUp({
pagination: {
limit: $pagelim // insert button value
}
});
Please help me solve this problem.
ID of an element must be unique... It looks like you want to update the limit option with the clicked button's text so
<button class="pagelimit default">1</button>
<button class="pagelimit">2</button>
<button class="pagelimit">3</button>
then
//this method is not used in the below code as we don't know which button was clicked here... if you share how the `displayVals` method is called then we can try to make this work
function displayVals() {
var pagelim = $("#pagelimit").val();
};
jQuery(function ($) {
$('.pagelimit').click(function () {
//update the limit option
$('#product-grid').mixItUp('setOptions', {
limit: +$(this).text()
});
});
//initialize the plugin
$('#product-grid').mixItUp({
pagination: {
limit: 1
}
});
})

I need to have multiple buttons on page (created through a PHP loop) - there's not fixed number of buttons as there'll be one for each record displayed. I'd like to get the value of that button with javascript when it is clicked.
So far the html looks like:
<button id="update[0]" value="test">Update</button>
<button id="update[1]" value="test">Update</button>
<button id="update[2]" value="test">Update</button>
etc....
and my script is:
$(document).ready("#update").click(function() {
var updateId = $("#update").val
alert(updateId);
});
So far the script detects when any #update[] button is clicked but how do I know the index of the particular button in order to get the value (i.e. if #update[38] is clicked how do I know it's #update[38] so I can find the value of that particular button?
Thanks.
You do not want to chain off the document ready like you are as its returning the document.
$(document).ready("#update").click(function() {
So you are capturing the document.click not not button.click so when you reference $(this).val() you will get document.value which does not exist.
Should be:
$(document).ready(function () {
$("button").click(function () {
//no reason to create a jQuery object just use this.value
var updateId = this.value;
alert(updateId);
});
});
http://jsfiddle.net/SeanWessell/2Lf6c3fx/
Use the "this" key word.
$(document).ready("#update").click(function() {
var updateId = $(this).val();
alert(updateId);
});
The this keyword in javascript allows you to reference the particular instance of the object you are interacting with.
Also, add "()" to the end of val.
I believe you meant to use
var updateId = $("#update").val()
With jQuery you can use $(this).val()
You could also get the text of the button using .text()
With pure Javascript you could use .value if the button has a value attribute
See this: Javascript Get Element Value
I would suggest the following
<button id="0" class="updatebutton" value="test">Update</button>
<button id="1" class="updatebutton" value="test">Update</button>
<button id="2" class="updatebutton" value="test">Update</button>
Use a class to apply your click function.
$(document).ready(function () {
$("updatebutton").click(function () {
var updateId = this.id;
alert(updateId);
});
});
And use the id to specify the index of the button.
The trick is to give all your buttons the same class and then use $(this) to find out which button was clicked.
Once you know the button, then you can check for any of its attributes like id, value or name.
$(function() {
$(".xx").on("click", function(evt) {
var clicked_button = $(this);
alert(clicked_button.attr("value"));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="update_1" class="xx" value="test1">Button 1</button>
<button id="update_2" class="xx" value="test2">Button 2</button>
<button id="update_3" class="xx" value="test3">Button 3</button>
Hi there a few things wrong with your javascript there.
You are attaching onClick to the document! The function ready returns the document.
Wrong:
$(document).ready("#update").click(function() {
Right:
$(document).ready(function () { $(valid_selector).click...
You are attempting to refetch the button with $('#update'), which 1 doesn't fetch anything, and two if it did would return all of the buttons. So use $(this) in the scope of the click function instead to refer to the button clicked.
Here is your javascript corrected:
https://jsfiddle.net/ffkekpmh/
//When the document is ready call this function
$(document).ready(function () {
//Select all buttons whoes id starts with update
//https://api.jquery.com/category/selectors/attribute-selectors/
$('button[id^="update"]').click(function() {
//Store the id attribute from the clicked button
var updateId = $(this).attr("id");
//Store the value attribute from the clicked button
var value = $(this).attr("value");
alert("You clicked button:"+updateId+" with value: "+value);
});
});
I am facing one issue, I want to disable anchor click after one click. I have
on-click attribute set in my anchor tag. Below is my HTML
<a style="cursor:pointer;" id="someId" onclick="Myfuntion()">Verify</a>
After I click "Verify" I am changing anchors text to "Verifying..." and one more thing I am trying to disable this anchor to avoid click in between the verification logic going on.
I have tried event.preventdefault() and also added disabled attribute to anchor.
But nothing works.
Please help!
If you were using jQuery for this you could have done this more easly.
Here we add a new class to a link to show that it has been clicked already. We check this when a click is made.
<a style="cursor:pointer;" id="someId">Verify</a>
$('#someId').on('click',function(){
//Check if button has class 'disabled' and then do your function.
if(! $(this).hasClass('disabled')){
$(this).addClass('disabled');
Myfuntion();
$(this).removeClass('disabled');
}
});
Here is a demo as to how it could be done using Javascript.
//Pass the event target to the function
function Myfuntion(elem) {
//If the element has no "data-status" attribute
if (!elem.getAttribute("data-status")) {
//Set attribute "data-status=progress"
elem.setAttribute("data-status", "progress");
//Change the text of the element
elem.textContent = "Verifying...";
//The setTimeout(s) below is only for the demp purpose
//Lets say, your verification process takes 4 seconds
//When complte
setTimeout(function() {
//Remove the attribute "data-status"
elem.removeAttribute("data-status");
//Notify the use that verification is done
elem.textContent = "Verified";
//Again, this is only for demo purpose
setTimeout(function() {
//User may verify again
elem.textContent = "Verify";
}, 1000);
}, 4000);
}
return false;
}

There are plenty of ways to do this; one simple approach is to just redefine the function itself:
var myFunction = function() {
alert('clicked');
// do whatever your function needs to do on first click, then:
myFunction = function() { // redefine it
// to no-op, or to another action
alert('second click');
}
}
<a onclick="myFunction()">click me</a>
I have the below html button which have onclick event
<button onclick="alert('button');" type="button">Button</button>
and the following js:
$('button').on('click', function(){
alert('jquery');
});
After executing some js code by jQuery/Javascript, i want to continue with the button onclick handler e.g: jquery alert first and than button alert.
i tried so many things like "remove attr and append it after executing my code and trigger click (it stuck in loop, we know why :) )" and "off" click. but no luck.
is it possible via jQuery/javascript?
any suggestion much appreciated
Thanks
A little bit tricky. http://jsfiddle.net/tarabyte/t4eAL/
$(function() {
var button = $('#button'),
onclick = button.attr('onclick'); //get onclick value;
onclick = new Function(onclick); //manually convert it to a function (unsafe)
button.attr('onclick', null); //clear onclick
button.click(function() { //bind your own handler
alert('jquery');
onclick.call(this); //call original function
})
});
Though there is a better way to pass params. You can use data attributes.
<button data-param="<%= paramValue %>"...
You can do it this way:
http://jsfiddle.net/8a2FE/
<button type="button" data-jspval="anything">Button</button>
$('button').on('click', function () {
var $this = $(this), //store this so we only need to get it once
dataVal = $this.data('jspval'); //get the value from the data attribute
//this bit will fire from the second click and each additional click
if ($this.hasClass('fired')) {
alert('jquery'+ dataVal);
}
//this will fire on the first click only
else {
alert('button');
$this.addClass('fired'); //this is what will add the class to stop this bit running again
}
});
Create a separate javascript function that contains what you want to do when the button is clicked (i.e. removing the onclick attribute and adding replacement code in its own function).
Then call that function at the end of
$('button').on('click', function(){
alert('jquery');
});
So you'll be left with something like this
function buttonFunction()
{
//Do stuff here
}
$('button').on('click', function()
{
alert('jquery');
buttonFunction();
});
<button type="button">Button</button>
I'm using the jQuery File Upload plugin. I'm hiding the file input and activating it upon clicking a separate button. (See this fiddle.)
HTML:
<div>
<button class="browse">Browse</button>
<input id="upload" type="file" style="display: none;" />
</div>
JavaScript:
var element = $("#upload");
$(".browse").click(function () {
$("#upload").trigger("click");
});
element.fileupload({
add: function () {
alert("add");
}
});
Notice that if you press the button then select a file, the add method is activated and you'll get an alert. Do it again, and you'll get another alert.
Now, see this fiddle. The only difference is that I've changed the following line
$("#upload").trigger("click");
to
element.trigger("click");
Notice that now, the first time you click the button then select a file, the add method is activated and you get the alert (just like before), but if you do it again, the add method never activates.
What is causing this difference in behavior?
This can also be solved by setting replaceFileInput to false, as stated by the documentation. This is because the plugin recreates the input element after each upload, and so events bound to the original input will be lost.
It looks as though the scope of element is being lost / changed after the add function. Resetting it like below seems to work.
var element = $("#upload");
$(".browse").click(function () {
element.trigger("click");
});
element.fileupload({
add: function () {
alert("add");
element = $(this);
}
});
Fiddle
Try this one: http://jsfiddle.net/xSAQN/6/
var input = $("#upload");
$(".browse").click(function () {
input.trigger("click", uploadit(input));
});
function uploadit(input){
$(input).fileupload({
add: function () {
alert("add");
}
});
}
Although there is one more way:
just change to this:
var element = $("#upload");
$(".browse").click(function () {
$("#upload").click(); // <----trigger the click this way
});
element.fileupload({
add: function () {
alert("add");
}
});
I'm trying to build a page which will have a scrolling list of Twitter search results (using twitter.search for jQuery). The user should be able to change the search term by clicking a button (so, clicking "Apple" will change the search term to "Apple".
I'm using a variable to set the search term. Setting that variable to a text string (i.e. searchText = "Pineapple";) works. But when I try to change the variable using the buttons, nothing happens.
//edit - the button doesn't seem to change the variable. Thoughts? Thanks.
<script type="text/javascript">
//set default value for searchText
searchText = "Pineapple";
//this sets up our Twitter stream
$(document).ready(function() {
$('#twitter-stream').twitterSearch({
term: searchText,
// no fade
animOut: { opacity: 1 },
avatar: false,
anchors: false,
bird: false,
colorExterior: 'white',
colorInterior: 'white',
pause: true,
time: false,
timeout: 2000
});
});
</script>
<script type="text/javascript">
$("#button-container").on("button", "click", function( e ) {
searchText = $(this).text();
});
</script>
<div id="twitter-stream" title="Mouse away to un-pause">
</div>
<div id="button-container">
<button class="button"> Apple </button>
</div>
<button onclick="alert(searchText);">Click me!
</button>
This code is very inefficient, you can use jQuery to define one function that handles all click events for the buttons, as opposed to 4 nearly identical functions.
Delegate your events using jQuery's .on:
$("#someContainerDiv").on("button", "click", function( e ) {
searchText = $(this).text();
});
This eliminates the need for an array of values, as you just take the innerText of the button itself.
