Click source in JavaScript and jQuery, human or automated?
(4 answers)
Closed 8 years ago.
I have an image and code
$(thisSrc).click();
How I can to distinguish physic mouse click by user
$(thisSrc).on("click", function () {
});
from program by javascript?
$(thisSrc).click();
There is isTrigger key in event when it's triggered.
$(el).click(function(e) {
if (e.isTrigger) {
// triggered
} else {
// clicked by hand
};
});
One way would be like this:
var realClick = true;
realClick=false;$(thisSrc).click();
$(thisSrc).on("click", function () {
// stuff
realClick=true;
});

(20 answers)
Closed 5 years ago.
if(!$('input:value').is(:checked)){
//do something
}
How do i do this, i can´t find an example?
I want to know if a checkbox with a specific value has been checked.
loop through checkboxex
and then check as below
var c=$(".commonclassname");
for(var i=0;i<c.length;i++)
{
if(c[i].value=="your value")
{
//matched...
}
}
Here's how to detect if a checkbox with a particular value gets unchecked
$("input[type=checkbox]").click(function() {
if ($(this).val() == "test2" && !$(this).is(":checked")) {
alert("Unchecked Test2");
}
});

How to differentiate single click event and double click event?
(22 answers)
Closed 6 years ago.
I have a simple program like:
<div onclick="handleClick(event)" ondblclick="handleDoubleClick(event)">
Hellooww world
</div>
<script>
var a = false
function handleClick(e) {
if(a) {
a = false
console.log("Hellooww", a)
}else{
a = true
console.log("Hellooww", a)
}
}
function handleDoubleClick(e) {
console.log("world")
}
</script>
Here on single click it sets the value of a to true of false.. But when its double click it perfomrs both single click and double click
How can I check only for single click and double click
This thread provides details on why the behavior is happening, but here is the solution to your specific use case. The one possible approach is to use timeout and some wait time. The problem is that there is no standard interval to wait. Although you could use the 300 ms timing that a mobile browser uses to distinguish between tap and double tap event:
var a = false;
var timeout;
function handleClick(e) {
timeout = setTimeout(function () {
if (a) {
a = false
console.log("Hellooww", a)
} else {
a = true
console.log("Hellooww", a)
}
}, 300);
}
function handleDoubleClick(e) {
if (timeout) {
clearTimeout(timeout);
}
console.log("world")
}
But generally, don't register click and dblclick events on the same element: it's impossible to distinguish correctly single-click events from click events that lead to a dblclick event.

Click event not working for dynamically added Li->span->id
(1 answer)
Closed 6 years ago.
If i add the search bar right away, it works, the console returns the value of the search field every time i press enter, but if i add the search bar after the image was clicked it doesn't work.
http://codepen.io/Nadaga/pen/QEVaGA
$('#glass-image').on('click', function() {
$('#main').html('<input id="search-field" type="text" placeholder="Search"></input>');
})
$('#search-field').keypress(function (e) {
if (e.which == 13) {
console.log($('#search-field').val());
return false;
}
});
Since, the search-field is dynamically created, It has to be added like this (on the $document),
$(document).on('keypress', '#search-field' ,function(e) {
if (e.which == 13) {
console.log($('#search-field').val());
return false;
}
});
$('#glass-image').on('click', function() {
$('#main').html('<input id="search-field" type="text" placeholder="Search"></input>');
$('#search-field').keypress(function(e) {
if (e.which == 13) {
console.log($('#search-field').val());
return false;
}
});
})
Click event only works if the element already exist in html code. So the click event doesn't fire.It won't consider the new element which is created dynamically after the page loaded. Dynamic elements are created with the help of javascript or jquery(not in html).

i am trying to add a new span of tag inside tags div.
my problem is that the code under span[id="newtag"] doesnt
work. how can i make this code work?
$(document).ready(function () {
$('#tags').on("click", function () {
$(this).append('<span id="newtag" contenteditable="true"></span>');
$(this).children(":last").focus();
});
$('span[id="newtag"]').keypress(function (k) {
if (k.which == 13 || k.which == 32) {
$(this).append('gfskjsokdfla');
}
});
});
Use event delegation for created dymanically dom elements.
$('#tags').on('keypress', 'span[id="newtag"]', function(k){
if (k.which == 13 || k.which == 32) {
$(this).append('gfskjsokdfla');
}
});

What's the effect of adding 'return false' to a click event listener?
(16 answers)
Closed 8 years ago.
When I try to add this line of code :
onclick="document.getElementById('part3').style.display='';return false;"
Into a link it disables the other function for some reason.. This is the code in which i would like to add the above code:
a href="javascript:DecreaseQuantity('PROD_VK_1.4')">
Works fine until i add the code, then only the onclick function works not the javascript part.
How can I fix this?
Try this,
<a href="javascript:DecreaseQuantity('PROD_VK_1.4')" onclick="doFunction()" />
function doFunction() {
document.getElementById('part3').style.display='';
return false;
}
or:
function doFunction() {
if ($("#part3").css("display", "")) {
return false;
} else {
return true;
}
}
