I'm using jQuery traversing to jump between DOM elements.
First of i have a onClick function:
$(document).on('keyup', '.size, .ant', function(){
Inside of this function I send data about what's clicked, to another function.
sulorTableRowWeight( $(this) );
function sulorTableRowWeight(thisobj){
Now, I'd like to traverse from the clicked element $(this)
to its parent. I'd like to find the parent's siblings and then traverse down to a specific sibling.
var inputSize = $(thisobj).parent().siblings('.sizeTd').children('.size');
My problem is when I want to traverse back down to the element I came from, it is not listed as a sibling because it isn't a sibling...
var inputSize = $(thisobj).parent().siblings(); console.log(inputSize)
console will give me the siblings, but not the one U came from...
So, when a user clicks ".size" I'd like to traverse up to the parent and back to size.... When a user clicks ".ant" I'd like to traverse up to the parent and then down to ".size"...
I tried to hardcode the traversing:
var inputSize = $(thisobj).parent().siblings('.sizeTd').children('.size');
But it won't work because it is not actually a sibling.
So what is it? And how can I get back to it?
If it is not possible, I have to run some if/else statements, U guess...
UPDATE
$(document).on('keyup', '.size, .ant', function(){
//Find changed <select> .tbody
var tbodyId = $(this).parent().parent('tr').parent('tbody').attr('id');
//Check <tbody> #id
if(tbodyId === "cpTableBody"){
}
else if(tbodyId === "sulorTableBody"){
sulorTableRowWeight( $(this) );
}
else if(tbodyId === "konturTableBody"){
konturTableRowWeight( $(this) );
}
else if(tbodyId === "kantbalkTableBody"){
kantbalkTableRowWeight( $(this) );
}
})
//Function sulorTableRowWeight
function sulorTableRowWeight(thisobj){
//Find the selected data-weight
var selectedWeightmm3 = $(thisobj).parent().siblings('.selectTd').children('.select').find(':selected').data('weightmm3');
//Find input .size value
var inputSize = $(thisobj).parent().siblings('.sizeTd').children('.size'); console.log(inputSize)
PROBLEM
My var inputSize
will return undefined when I click a ".size" element. That´m's because it is not listed as a sibling to itself.
I know it's keyup, not click...
e.target will select the current input
$(document).on('keyup', '.size, .ant', function(e) { inputSize = $(e.target); if($(e.target).is('.ant')) {//test if the element is .ant inputSize = $(e.target).parent().find('.size');//get .size based on .ant } console.log(inputSize[0]); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div> <input class="size x1" placeholder="x1"> <input class="ant x1" placeholder="x1 ant"> </div> <div> <input class="size x2" placeholder="x2"> <input class="ant x2" placeholder="x2 ant"> </div>
Hmm, if you're passing in $(this)
as thisObj
I don't think you need to be nesting thisObj
in a $()
. (See note below)
Anyway, you could try using .parents('<grandparent>').find('<child>')
so basically you're traversing one higher level up the tree with <grandparent>
, then getting all the descendants that match the child selector. That should include the branch of the three that $(this)
represents. But it's hard to say for sure without seeing your HTML.
** A good practice when assigning jQuery objects to variables is to use $
syntax, ie var $this = $(this)
so you know anything prepended with a $
is a jQuery object.
在sulorTableRowWeight
内部,您应该在thisobj
变量中具有对clicked元素的引用。
