can anyone please tell me why i'm getting undefined in javascript when i run the below code.
its a simple code for getting the parent div id. All div's are closed properly but still getting undefined.
html
<div id="ricolaId_2" class="ricMo ricIndex ricBlocking ricInline" style="width: 730px; left: 309px; top: 144px; z-index: 13000; display: block;">
<div class="ricTitle">
<a class="ricClose">
<span class="ui-icon ui-icon-close" title="Close">
</span>
</a>
<span class="ricTitle">Manage</span>
</div>
<div class="ricModal ng-scope" style="height: auto;">
<div>
<div>
<div ng-controller="Manage" class="ng-scope">
<div class="ricCenter">
<div class="ricport">
<div class="ricWr">
</div>
</div>
</div>
</div>
<br style=""></br><br style=""></br>
<div align="center" class="row btn-group">
<button onclick="cancel(this)" class="ricSmall" type="button" id="sss" ric:loaded="true">Close</button>
</div>
</div>
</div>
</div>
</div>
script
function cancel(btn)
{
try{
ricId_1 = $(btn).parent().parent();
alert(ricId_1.attr("id"));
}catch(a){alert(a);}
}
To target that id you need:
$(btn).parent().parent().parent().parent().parent();
or:
$(btn).closest('.ricModal').parent();
Demo
Use parents instead of .parent()
function cancel(btn)
{
try{
ricId_1 = $(btn).parents('#ricolaId_2');
alert(ricId_1.attr("id"));
}catch(a){alert(a);}
}
parent method only travels a single level up the DOM tree and parents method travels through multiple level up the DOM tree.
I changed a few things, and look: It's working! You should add an id to ng-scope So, http://jsfiddle.net/8F8Mr/7/

Hey all I am having the worst time trying to figure out why my XPath code below is not able to find the Image tag and the HREF link that goes with it within my document.
The XPath (full) looks like this:
//html/body/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/a/div/svg/g/descendant::image[starts-with(#href,'https://')]
The javascript code I am using is:
function checking(Path) {
const nodes = document.evaluate(Path, document, null, XPathResult.ANY_TYPE, null);
const result = {
Data: []
};
let attr = nodes.iterateNext();
result.Data.push({ href: attr});
return JSON.stringify(result);
}
console.log(checking("//html/body/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/div/a/div/svg/g/descendant::image[starts-with(#href,'https://')]"));
And the HTML that I am looking through to get said image Xlink:HREF:
<body class="">
<div id="" style="">
<div>
<div class="">
<div class="">
<div class="">
<div class="">
<div class="">

</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</body>
I keep getting NULL for the output for some reason? And here is a jsfiddle to visually test it.
{
"Data": [
{
"href": null
}
]
}
Anyone have a clue as to why I am?
UPDATE 1
Checking the "offical" xPath to my project comes out to be this:
// html/body/div1/div/div1/div/div3/div/div/div1/div1/div/div/div1/div2/div/div/div/div1/div/div/svg/g/image
Which I change the latest fiddle to reflect what #bigless suggested in his fiddle but still get null.
Newest fiddle
Alternative to #Jack Fleeting answer (skipping all those divs just for example) with xlink:href selector:
string(//*[name() = 'svg']/*[name()='g']//*[name()='image' and starts-with(#*[name()='xlink:href'],'https://')]/#*[name()='xlink:href'])
This will extract just attribute value as a string (first occurence)
A few things:
First, you have a problem with namespaces and Deprecated XLink URL reference attributes.
Second, in
result.Data.push({
href: attr
});
you should push the node value of the attribute:
result.Data.push({
href: attr.nodeValue
});
Finally, because of the namespace issue, and to simplify the xpath expression, change your comeback to
var comeback = checking("//*[local-name()='image'][starts-with(./#href,'https://')]/#href");
And it should work as in this fiddle.
I've been searching for the solution for a few days but unable to find one that works. The issue is that this div which has a class ish-container-inner, is linked to a js plugin which works only with this code below:
<div class="ish-container-inner ish-product">
<div class="ish-main-content ish-pflo-gal ish-scroll-anim ish-2col ish-square ish-content-parallax">
<div class="ish-item">
<div class="ish-item-container">
<div class="ish-caption-container">
<div class="ish-caption">
<span class="ish-h4 ish-txt-color9">Special Effects</span> <span class="ish-separator">/</span> <span>Ink</span></div>
</div>
<div class="ish-img">
<img src="assets/img/bniinks-003.jpg" alt="Project">
</div>
</div>
</div>
</div>
</div>
But as soon as I'll put *ngFor like below, it won't work. Even with ngIf present:
<div class="ish-container-inner ish-product" *ngIf="products">
<div class="ish-main-content ish-pflo-gal ish-scroll-anim ish-2col ish-square ish-content-parallax">
<div class="ish-item" *ngFor="let product of products">
<div class="ish-item-container">
<div class="ish-caption-container">
<div class="ish-caption">
<span class="ish-h4 ish-txt-color7">{{ product.name }}</span> <span class="ish-separator">/</span> <span>Ink</span>
</div>
</div>
<div class="ish-img">
<a href="product-detail.html" class="ish-img-scale" [style.background]="'url('+product.thumbnail+')'">
<img src="{{product.thumbnail}}" alt="Project"></a>
</div>
</div>
</div>
</div>
</div>
I have valid data at this point in products but the plugin is not working for these div elements. I don't know why. Without the ngFor directive. Div is assigned some stylings automatically which are changed by the plugin on scroll i.e.
<div class="ish-main-content ish-pflo-gal ish-scroll-anim ish-2col ish-square ish-content-parallax" style="position: relative; height: 629px; margin-top: -99.5455px;" data-initial-top="0">
But if I put ngIf or ngFor directive. It doesn't work anymore and these stylings are not assigned automatically. Awaiting response :)
So, I had a working function in jQuery but then I decided to use Angular for my application. Just can't find the way so it adds the CSS to only one child element.
Jquery code that was working
$('.list-div').on('mouseenter', function(){
$(this).find('.client-jar').css('opacity','1');
}).on('mouseleave', function() {
$(this).find('.client-jar').css('opacity','0');
});
Current html
<ul>
<li ng-repeat="one in ones | orderBy:'-date'">
<div class="list-div">
<div class="row jar-div first-jar-div" ng-mouseover="showButton()" ng-mouseleave="hideButton()">
<div class="col-xs-7 description-div">
<p class="version">{{ one.version }}</p>
<p class="date">{{ one.date }}</p>
</div>
<div class="col-xs-5 buttons-div">
<div class="list-button client-jar">
<a class="list-link" data-toggle="modal" data-target="#myModal">create server</a>
</div>
<div class="list-button server-jar">
<a class="list-link">Server jar</a>
</div>
</div>
</div>
</div>
</li>
</ul>
And Current Angular JS
$scope.showButton = function(){
angular.element('.list-div').find('.client-jar').css('opacity','1');
};
$scope.hideButton = function(){
angular.element('.list-div').find('.client-jar').css('opacity','0');
};
I would use:
https://docs.angularjs.org/api/ng/directive/ngMouseenter
<button ng-mouseenter="hoverState = true">mouse in mouse out</button>
Then use with:
https://docs.angularjs.org/api/ng/directive/ngMouseleave
<button ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false">mouse in mouse out</button>
At this point you have a hover over and off flag. You can now pick this flag up with ng-class to set and unset a CSS class which contains your opacity stuff, and any future CSS animations etc etc:
https://docs.angularjs.org/api/ng/directive/ngClass
<button ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false" ng-class="{'opacity-class':hoverState}">mouse in mouse out</button>
No jQuery required, AngularJS is just a totally different way of going about things.
<style>
.opacity-class .client-jar{
opacity:0;
}
</style>
<ul>
<li ng-repeat="one in ones | orderBy:'-date'">
<div class="list-div">
<div class="row jar-div first-jar-div" ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false" ng-class="{'opacity-class':hoverState}">
<div class="col-xs-7 description-div">
<p class="version">{{ one.version }}</p>
<p class="date">{{ one.date }}</p>
</div>
<div class="col-xs-5 buttons-div">
<div class="list-button client-jar">
<a class="list-link" data-toggle="modal" data-target="#myModal">create server</a>
</div>
<div class="list-button server-jar">
<a class="list-link">Server jar</a>
</div>
</div>
</div>
</div>
</li>
</ul>
angular.module('App').directive('listFade', function() {
return function(scope, element) {
element.bind('mouseover', function(children) {
// YOUR ANIMATION CODE HERE
});
element.bind('mouseout', function(children) {
// YOUR ANIMATION OUT CODE HERE
});
}
})
then just add the directive to your ng-repeat markup, list-fade=""
you don't need children but its a easy way to call the children of each element. This should help you out. Then get rid of that ng-mouseover showButton();
Updating your code to use inline CSS, would be like this.
var element = document.querySelector('.list-div .client-jar');
$scope.showButton = function(){
angular.element(element).css('opacity','1');
};
$scope.hideButton = function(){
angular.element(element).css('opacity','0');
};
As in AngularJS .element documentation, it's said that you need to pass a element.
You can also use ng-class, creating a class for opacity:
<div class="client-jar" ng-class="{class: expression}"></div>
https://docs.angularjs.org/api/ng/directive/ngClass
Or use ng-show and ng-hide for display control:
<div class="client-jar" ng-show="expression"></div>
https://docs.angularjs.org/api/ng/directive/ngShow
You could even use ng-style for inline css:
<div class="client-jar" ng-style="{'opacity': '1'}"></div>
https://docs.angularjs.org/api/ng/directive/ngStyle
I am trying to create a comparison overlay that shows items selected by users when they 'add to compare' link.(like one in flipkart that appears on top when you hit add to compare). Here is my code:
<div class="college-list-container">
<div class = "individual-college-container" id="text1">
<div class="image-header"><h3>text1</h3>
</div>
<div class="dark-overlay">
<div class="overlay-links" style=" float:left;"> <div class="absolute-center ">Details</div></div>
<a href=""> <div class="overlay-links" style=" float:right; border-right:none;"> <div class="absolute-center comparison" id="comparison">Add to compare</div>
</div></a>
</div>
</div>
<div class = "individual-college-container">
<div class="image-header"><h3>text2</h3>
</div>
<div class="dark-overlay">
<div class="overlay-links" style=" float:left;"> <div class="absolute-center ">Details</div></div>
<a href=""> <div class="overlay-links" style=" float:right; border-right:none;"> <div class="absolute-center comparison">Add to compare</div>
</div></a>
</div>
</div>
<div class = "individual-college-container" id="itm">
<div class="image-header" ><h3>text3</h3>
</div>
<div class="dark-overlay">
<div class="overlay-links" style=" float:left;"> <div class="absolute-center ">Details</div></div>
<a href=""> <div class="overlay-links" style=" float:right; border-right:none;"> <div class="absolute-center comparison">Add to compare</div>
</div></a>
</div>
Javascript
/show overlay when one checkbox is checked and add its name/image to the empty space
$('.comparison').click(function(e){
var clgId = $(this).parentsUntil('.individual-clg-container').find('.image-header').text();
e.preventDefault();
var clg = $("<li></li>")
clg.text(clgId);
var removeLink = $("<a href=''>(Remove)</a>");
clg.append(removeLink)
$('.comparison-colleges').append(clg);
$('.add-to-compare-overlay').show("slide", { direction: "up" }, 300);
});
I want the text in the div containing class 'image-header' to be assigned to the variable clgId. The problem that i am facing with my code is that it is adding the text of all the divs containing class 'image-header'. Ex i want the value text1 to be assigned on clicking add to compare of the div with id text1. However it assigns 'text1 text2 text3' to clgId.
Please help
I've created a JSFiddle with what I think is your desired functionality (I included a console log output in the script of the clgId variable):
http://jsfiddle.net/py38kuvv/
I replaced the parentsUntil function with the closest function (and replaced the individual-clg-container class selector):
var clgId = $(e.target).closest('.individual-college-container').find('.image-header').text();
and also updated your click handler:
$('.comparison').on( "click", function(e) {
In order to get a quicker response in future, posting a JSFiddle of what you have so far makes it easier for others to help :)
It is adding all of them because
var clgId = $(this).parentsUntil('.individual-clg-container').find('.image-header').text();
should be
var clgId = $(this).parentsUntil('.individual-college-container').find('.image-header').text();
I am new to jQuery and am trying to write a script that will run through a menu list and display the correct background image based on the menu item. The menu list is going to be randomly populated so a script is necessary to load the correct image.
The problem is that the attribute where I am able to see which item the menu belongs to is not on the list item itself but on a div contained inside the list item. My question is is it possible to select a child element of the already selected element ?
E.g (the menuli a segment)
$(document).ready( function() {
$(menuli).each( function(index) {
$itemnumber = $(menuli a).attr("href");
switch($itemnumber) {
case 1:
$(this).css("background-image", "image01.jpg");
break;
}
});
});
This is more or less the script I am trying to get, where each list item is iterated through and depending on the href of the link inside the list item a background image is set to that list item.

Yes you can, use find
var parentElement = $('#someElement');
var childElement = parentElement.find('.child'); //where .child should be your child selector
Where as example code is not clear, I just gave answer to your question.
try to change this:
$(this).css("background-image", "image01.jpg");
to this:
$(this).children("div").css("background-image", "image01.jpg");
If you want to target the direct child of the element, better to use children() than find()
Please refer to this: What is fastest children() or find() in jQuery?
