Extracting value from a div sent in to javascript - javascript

Im attempting to get the ID of the specific box that i call.
<div id="box1" onmouseover="transition(box1)" onmouseout="detransition(box1)">
<div class="box1-smallbox">
</div>
function transition(prop){
document.getElementsByTagName(prop + "-smallbox").style.marginLeft = X;
}
I want to get that prop = box1. For a easy system that then can be used with 10 or 20 boxes.
Thanks in advance!

without jquery, only javascript:
<div id="box1" onmouseover="transition(this.id)" onmouseout="detransition(this.id)">
<div class="box1-smallbox">aaa</div>
</div>
<div id="box2" onmouseover="transition(this.id)" onmouseout="detransition(this.id)">
<div class="box2-smallbox">bbb</div>
</div>
<div id="box3" onmouseover="transition(this.id)" onmouseout="detransition(this.id)">
<div class="box3-smallbox">ccc</div>
</div>
<script type="text/javascript" language="javascript">
function transition(prop){
var els = document.getElementsByTagName("div");
for(var i=0;i<els.length;i++){
if(els[i].className==prop+"-smallbox"){
els[i].style.marginLeft = 200;
}
}
}
function detransition(prop){
var els = document.getElementsByTagName("div");
for(var i=0;i<els.length;i++){
if(els[i].className==prop+"-smallbox"){
els[i].style.marginLeft = 0;
}
}
}
</script>

Turn it into a string since you want to pass it's id as string
onmouseover="transition('box1')"

How to loop and set inner content of DOM elements in jQuery and JavaScript?

I'm trying to loop through divs and set the content of a div inside the outer div. I tried this.
Here is the HTML div's I want to loop through and I want to set the content of div with class content-detail with the value for its attribute data-form data.
//the javascript code I used is this
$(function($) {
for (var i of $(".item .content-detail")) {
var container = document.querySelector($(i)[0]);
var formData = $(i).attr("data-formdata");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script>
<div class="item">
<div class="down-div"> </div>
<div class="detail">
<h4>Detail</h4>
<div id="div_" class="content-detail" data-formdata="my Item">
</div>
<div class="text-center">
<button class="btn btn-blue center"> SET !</button>
</div>
</div>
</div>
<div class="item">
<div class="down-div"> </div>
<div class="detail">
<h4>Detail</h4>
<div id="div_" class="content-detail" data-formdata="my Item">
</div>
<div class="text-center">
<button class="btn btn-blue center"> SET !</button>
</div>
</div>
</div>
But am stuck at this point var container = document.querySelector($(i)[0]);
I don't know how to get the jquery selector of that current div to a variable.
This may need some tweaks, but it should be close...
$(function ($) {
$(".item .content-detail").each(function(index, element) {
element.text($(element).attr("data-formdata"))
})
});
Take a look at the .each() method
$(function($) {
for (var i of $(".item .content-detail")) {
//var container = document.querySelector($(i)[0]);
var container = i;
var formData = $(i).attr("data-formdata");
}
});
I just needed the element
If you want to set the content of each DIV, you don't need a for loop. The .text() method takes a callback function, and it will be called on each element that matches the selector. The returned value is used as the new content.
$(".item .content-detail").text(function() {
return $(this).data("formdata");
});
This works.
$(function($) {
$(".item .content-detail").text(function(){
return $(this).attr("data-formdata");
})
});
Can you not just use JS like this:
[UPDATED]
function test() {
var divs = document.getElementsByTagName("div");
for (var i = 0; i < divs.length; i++) {
var divsSub = divs[i].getElementById("div_").querySelectorAll(".content-detail");;
for (var iS = 0; iS < divsSub.length; iS++) {
var x = divsSub[iS].getAttribute("data-formdata");
divsSub[iS].innerHTML = x;
}
}
}

add div using appendChild

This code is supposed to be looping and adding multiple divs, but it isn't working. When I click it, only one div appears. If I click again, nothing happens.
<body>
<div class="start" >
<div id = "coba">
</div>
<div id = "cobi">
</div>
</div>
<script>
var divs = document.getElementById("coba").addEventListener("click", function () {
for (var i = 1; i < 100; i++) {
var di = document.createElement('div');
document.getElementById('coba').appendChild(di);
}
});
</script>
</body>
Thanks for your help
Your code does not work because you did not do anything with the variable "i" in the for statement. If you look at the fiddles of user2181397 & meghan Armes you will see how they added a line in the script to put it to work.
I tested the below in my IDE and it works just fine:
<body>
<div class="start" style="margin-top:50px; color:black;">
<div id = "coba">
<p>Click Me</p>
</div>
<div id = "cobi">
</div>
</div>
<script>
var divs = document.getElementById("coba").addEventListener("click", function() {
for (var i = 1; i < 100; i++) {
var di = document.createElement('div');
di.innerHTML=i;
document.getElementById('coba').appendChild(di);
}
});
</script>
</body>

use innerHTML to select class only if it is in a parent div

i currently have the code below which searches for the class and will replace the text.
how would i tweak it so it only will replace text if the parent tag is "#thumb-hockey-top"?
window.onload = function(){
//this captures all the elements with the spec classes
var soldItems = document.getElementsByClassName('product-mark sold-out');
//this changes each element 1 by 1 to new text
for(var i=0; i<soldItems.length; i++){
soldItems[i].innerHTML = "Coming Soon";
}
}
window.onload = function(){
//this captures all the elements with the spec classes
//just use a class
var soldItems = document.getElementsByClassName('sold-out');
//this changes each element 1 by 1 to new text
//var parentnode = document.getElementById('thumb-hockey-top')
for(var i=0; i<soldItems.length; i++){
if(soldItems[i].parentNode.id=='thumb-hockey-top'){
soldItems[i].innerHTML = "Coming Soon";
}
}
};
<div id="thumb-hockey-top">
<div class="product-mark sold-out"></div>
<div class="product-mark sold-out"></div>
<div class="product-mark sold-out"></div>
</div>
Use once
window.onload = function(){
//this captures all the elements with the spec classes
var soldItems = document.getElementById("thumb-hockey-top").getElementsByClassName('product-mark sold-out');
//this changes each element 1 by 1 to new text
for(var i=0; i<soldItems.length; i++){
soldItems[i].innerHTML = "Coming Soon"
}
}
<div id="thumb-hockey-top">
<div class="product-mark sold-out"></div>
</div>
<div class="product-mark sold-out"></div>
<div class="product-mark sold-out"></div>
Use multiple times
function myF(a, b){
// a = Id of parent element
// b = Class Name of element which you want to hack
var soldItems = document.getElementById(a).getElementsByClassName(b);
for(var i=0; i<soldItems.length; i++){
soldItems[i].innerHTML = "Coming Soon"
}
}
myF("thumb-hockey-top", "product-mark sold-out");
myF("thumb-hockey-bottom", "product-unmark sold-out");
<div class="example1">
<div id="thumb-hockey-top">
<div class="product-mark sold-out">EXAMPLE 1</div>
</div>
<div class="product-mark sold-out">EXAMPLE 1</div>
</div>
<div class="example2">
<div id="thumb-hockey-bottom">
<div class="product-unmark sold-out">EXAMPLE 2</div>
</div>
<div class="product-unmark sold-out">EXAMPLE 2</div>
</div>
You can get the parent element of an element using the parentElement attribute. Then just check its id.
var soldItem = soldItems[i];
if (soldItem.parentElement.id == "thumb-hockey-top") {
// do your thing
}

tSort on jQuery object

I'm trying to sort the results of a jQuery selection with tSort.
HTML:
<div sort="2"></div>
<div sort="3"></div>
<div sort="1"></div>
<div sort="4"></div>
<div sort="6"></div>
<div sort="5"></div>
Javascript:
<script>
$sort_order = $('div').tsort({attr:'sort'});
</script>
I want the result to be: 1,2,3,4,5,6 in the jQuery object, not yet inserted into the page.
Is this possible with tSort, or should I write my own algorithm?
It is easier to do it if there is a wrapper of all the div elements.
HTML:
<div id="wrapper">
<div sort="2">2</div>
<div sort="3">3</div>
<div sort="1">1</div>
<div sort="4">4</div>
<div sort="6">6</div>
<div sort="5">5</div>
</div>
Javascript (with jQuery):
var $wrapper = $('#wrapper');
$wrapper.find('div').sort(function (a, b) {
return +a.getAttribute('sort') - +b.getAttribute('sort');
})
.appendTo($wrapper);
Working demo.
In response to #Tim's comment, you can place the elements that do not have the sort attributes at the back of the wrapper element easily, even without jQuery.
Assuming that this is your HTML:
<div id="wrapper">
<div style="color:red;">red color, without sort attribute</div>
<div style="color:red;" sort="7">red color (sort attribute=7)</div>
<div sort="2">2</div>
<div sort="3">3</div>
<div sort="1">1</div>
<div sort="4">4</div>
<div sort="6">6</div>
<div sort="5">5</div>
</div>
You can place the element(s) that do not have the sort attribute by having this as your Javascript:
// As shown earlier above,
var $wrapper = $('#wrapper');
$wrapper.find('div').sort(function (a, b) {
return +a.getAttribute('sort') - +b.getAttribute('sort');
})
.appendTo($wrapper);
// New code to add:
var divs = document.getElementsByTagName('div');
for(var i = 0; i < divs.length; i++) {
if(divs[i].getAttribute('sort') == null || divs[i].getAttribute('sort') == undefined) {
divs[i].parentNode.appendChild(divs[i]);
}
}
Working demo.
clone it before using .tsort
$sort_order = $('div').clone().tsort({attr:'sort'});

Hide DIVs with the same name using Javascript

I want to hide all divs with the name "mask"
This is my HTML:
<div id="first">
<div id="firsttest"></div>
<div class="one onehelp">
<div id="mask">
<div id="onetip"></div>
</div>
<div id="Div5"></div>
<div id="resultone"></div>
</div>
<div class="two twohelp">
<div id="mask">
<div id="twotip"></div>
</div>
<div id="Div6"></div>
<div id="resulttwo"></div>
</div>
<div class="three threehelp">
<div id="mask">
<div id="threetip"></div>
</div>
<div id="Div7"></div>
<div id="resultthree"></div>
</div>
</div>
I tried to hide "mask" by using the JS code below but it didn't work for all divs, just for the first one.
var hidemask = document.getElementById("mask");
hidemask.style.display = "none";
Is there a way to hide them all by using pure Javascript. No jQuery.
You shouldn't be using duplicate ID's in HTML, consider changing it to a class.
If you change id="mask" to class="mask", then you can do:
var hidemask = document.querySelectorAll(".mask");
for (var i = 0; i < hidemask.length; i++) {
hidemask[i].style.display = "none";
}
Or for browsers still in the stone age (IE7 and below), you can do:
var elems = document.getElementsByTagName('*'), i;
for (i in elems) {
if((' ' + elems[i].className + ' ').indexOf(' ' + 'mask' + ' ') > -1) {
elems[i].style.display = "none";
}
}
The id attribute must be unique per document. You can do what you want with a class, perhaps. So you would have multiple divs like so:
<div id="something" class="mask"></div>
Then you can do:
var divsWithMask = document.querySelectorAll(".mask");
for(var i = 0; i < divsWithMark.length; i++) {
divsWithMak[i].style.display = "none";
}
You cannot assign same ID more than once.
But you can add an attribute class to div with id "mask" E.g.:
<div id="mask-or-something-else" class="mask">...</div>
And select all elements by this class:
var hidemask = document.getElementsByClassName("mask");
for(i = 0; i < hidemask.length; i++)
hidemask[i].style.display = "none";
