jquery selector on multiple id
(2 answers)
Closed 5 years ago.
Sorry for that simple question, but how do I add multiple triggers to a jquery-click-event?
I tried that one here
$("#trigger1","#trigger2").click(function() {
//something
});
But that doesn't work. What is the correct syntax there?
Should be like :
$("#trigger1, #trigger2").click(function() {
//Put your logic here
});
Just remove the extra quotes.
Hope this helps.
The reason why your code is not working is you are using a context selector. So what it is saying is: Find #trigger2 and inside of that look for #trigger1.
But what you want is to use a multiple selector.
$("#trigger1, #trigger2").click( ... )
Or I would just use a common class so you do not have to keep track of the ids
$(".commonClass").click( ... )
Or something like
$(document).on("click", "#trigger1, #trigger2, #trigger3", function () {
//do stuff
});
This will let you add as many listeners as you want on multiple DOM elements

Javascript getElementById based on a partial string

I just want to know to how to use custom varible with javascript.suppose we have 5 id with name zawsz,baws2,tawsx,paws4,vawsa and we want to execute single DOM command to all these element whose id is define here.
document.getElementById("-aws-").onclick=function(){}
Here -aws- define all the id define above.(-) can be replace with any char/int value;
You could use the following code:
(The following code will select all elements of which the id includes aws.
I have tested this code and it works: https://jsfiddle.net/5042woqz/)
document.querySelectorAll('*[id*="aws"]').forEach(function(item) {
item.onclick=function() {
console.log('click!');
};
});
Items will now be an array containing all your aws- items.
If you have further questions, just let me know.
P.S.: You could achieve the same thing really easily with jquery.
You can use document.querySelectorAll for this:
document.querySelectorAll('[id^="aws"]')
That will select all elements where the id attribute starts with (^=) "aws".

What do querySelectorAll and getElementsBy* methods return?
(12 answers)
Closed 5 years ago.
I have looked around and I haven't really been able to find anything that solves my problem. There is a post using buttons but I can't seem to modify it for my needs.
I am trying to use only one event listener for multiple selects. I'd like to return the id of the select, and the value selected but as far as I can figure I either need to use document.getElementById("ID").addEventListener('change',func(),true) for each id or document.getElementsByTagName('select').addEventListener('change', func(), true) and I get an error that says:
selection.addEventListener is not a function. (In 'selection.addEventListener('change', func(), true)', 'selection.addEventListener' is undefined)
I was hoping someone could take a moment and show me where I am going wrong or if I need to use a different method to accomplish my task.
thanks for the help
The method getElementsByTagName returns HTMLCollection of elements, and not a DOM Element, so you can't use addEventListener on that.
What you can do is go over all the elements in the HTMLCollection and add the event you want to them:
let selectElements = document.getElementsByTagName('select');
Array.prototype.forEach.call(selectElements, function(el) {
eladdEventListener('change', func(), true)
})

jQuery hasAttr checking to see if there is an attribute on an element [duplicate]
(9 answers)
Closed 5 years ago.
How do I find a certain attribute exists or not for a selected item in jQuery?
For example, selected element jQuery('.button'), now this can have an attribute 'xyz'. How do I get whether it is having that or not?
You can use the hasAttribute method:
// Attach the event to the button
$('button').on('click', function() {
// This will refer the element from where event has originated
if (this.hasAttribute("style")) {
alert('yes')
} else {
alert('no')
}
})
If you want to use the jQuery library, you can directly use the attr method in the if condition.
if($('#yourElement').attr('someProp')){}
Alternatively, you can also use the jQuery is selector:
if ($(this).is('[style]')) {// rest of the code}
DEMO
You have two solutions that I know of. 1) Native Javascript has a function for this .hasAttribute() (e.g. $(this)[0].hasAttribute('name');). 2) Using jQuery, you can check if $(this).attr('name') is undefined or not.

How do you assign an event handler to multiple elements in JavaScript?

Closed 7 years ago.
I am trying to run a function when user clicks on a class.
Here is a fiddle with a similar setup. Except that I am not using buttons in the my code.
FIDDLE
document.querySelectorAll('.menu').onclick = function () { alert("test"); };
I've also tried using the getElementsByClassName, with the same results. Is there something I am missing here?
*Note: I need to accomplish this without jQuery
querySelectorAll returns a list of elements, so you need to specify the one you want, in your case [0]:
document.querySelectorAll('.menu')[0].onclick = function () {
alert("test");
};

How to use JavaScript variables in jQuery selectors?
(6 answers)
Closed 8 years ago.
Its a simple question, could not find an answer from google.
Code
$.click(function(){
var curID = $(this).parent()[0].id;
$("#"+curID input).attr("checked",true);
});
Onclick function is giving me the parent id, Now, using the parent id i want to find the input element and add checked attribute.
I am not sure of the syntax of querying by dynamic ID.
I want to know how can i query by dynamic variable.
Thanks in advance.
$("#"+curID).find('input').attr("checked", true);
Or
$(this).parent().find('input').attr("checked", true);
Or
$('input', $(this).parent()).find('input').attr("checked", true); // using the scope argument
The selectors are strings... So should be handled as strings by concatenating the variables: and texts
$.click(function(){
var curID = $(this).parent()[0].id;
$("#"+curID+" input").attr("checked",true);
});
Your search is probably too specific. Break tasks down into their components instead of looking for a complete solution to a very specific problem. You are just dealing with basic string concatenation here.
You want:
var selector = "#foo input";
You have foo in a variable.
var selector = "#" + foo_variable + " input";
