I have requirement where I wanted to find the amount fields like $412,341.40 from document.
I tried $("div:contains($)").css("background-color","yellow") but it returning parent div's also, and i just wanted color the child ones.
for e.g see the below image, the above jquery coloring both div's parent and child.
How can i color child div only? I am trying find all div's which contains string like $123,55.60.
Any help is greatly appreciated.
This will give your the direct parent.
$('div>:contains("$")').last().css("background-color","yellow")
JSFIDDLE DEMO
EDIT: The above will work great for only one occurrence of $. For multiple occurrences of text, use below code. This makes use .each() and looks for a closing </div> tag each time.
var divs = $('div>:contains("$")');
divs.each(function() {
var htmlinner = $(this).html();
if(htmlinner.indexOf('</div>') == -1) {
$(this).css("background-color", "yellow");
}
});
JSFIDDLE DEMO[2] for multiple occurrences
use:
$("div:contains('$')").find('div').css("background-color","yellow")

I have a page with numerous divs. The main div contains 3 sub divs. I put a search box and i want to show the main div based on what i type and hide the others.
I looked on the internet and so far i managed to do this: https://jsfiddle.net/qaho8hjt/6/
$('.my-textbox').keyup(function() {
var value = $(this).val();
var exp = new RegExp('^' + value, 'i');
$('.change_req .orizontala').each(function() {
var isMatch = exp.test($('.projectName', this).text());
$(this).toggle(isMatch);
});
});
The problem is that i don't know how to hide the parent div. I can only hide the div that i search for.
Thank you.
Edit: Thank you all for you're responses.
Code is almost fine, just that you are hiding the div that has the content where you should be hiding its immediate parent, demo
replace
$(this).toggle(isMatch);
with
$(this).parent().toggle(isMatch);
You can use closest() to get the nearest containing div. Try this:
$(this).closest('.change_req').toggle(isMatch);
Updated fiddle
Try like this:
$(this).parent().toggle(isMatch);
See your edited code here.
So I try to select a div within another div. My html goes like this:
<div id="Stage_game_page1"><div id="cube0">[...]</div><div id="cube1">[...]</div></div>
I want to select my #cube0 within my Stage_game_page specifically, with jQuery or JS.
The goal of the selection is to use it in an loop.
I tried :
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#Stage_game_page")$("#cube"+i)[...]
}
I don't understand what I'm doing wrong.
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#cube"+i);
}
This is sufficient to select the "#cube0"/"#cube1"/"#cube2" etc. especially since ids are always unique. To answer the question $("#cube0", "#Stage_game_page")... that is how you select a div in another div
The id attribute should only be used once! I see above that you're using id="cube0" twice. If you want your divs to be recognized in multiple instances, use a class instead (the . instead of the #). Using the same id twice will probably break your script.
I believe for your html, you could use id "cube0", "cube1", etc., as long as you're ok with entering them manually. That should work for the loop you'd like to use.
Loops through each div that starts with the id cube inside Stage_game_page1
$("#Stage_game_page1 > div[id^='cube']").each(function () {
alert($(this).html());
});
JSFiddle
Child Selctor
Starts with Selector
use each() for loop.
$('#Stage_game_page1').children().each(function(index) {
// your code here with index starts from 0
});
or this using jquery attribute starts with selector
$('#Stage_game_page1').find('[id^="cube"]').each(function(index) {
// your code here
});
You need to use .find() or .children() or the like.
The correct jQuery usage would be
$("#Stage_game_page").find('#cube'+i)
to find a div with that id inside the container #stage_game_page
You have duplicate cube0 in your html code..
and i think the look should contain something like that:
$("#cube"+i)[...]
One another solution is:
$("#Stage_game_page1 div[id='cube0']")
I was wanting to have a javascript (jQuery) function that removed everything that didn't have the safe class.
The problem is, if the parent element is hidden, it cannot show the 'safe' part of it.
Is there a simple way to get around this? I'd rather not go in and span all of the elements that need removed.
trimmer = function(element){
x = $(element+' *:not(.safe)');
x.hide();
}
trimmer('section');
Fiddle
var element = 'section';
//finds all non `.safe` elements in `section`s and hides them
$(':not(.safe)', element).hide();
//finds all `.safe` elements in `section`s and shows the `section`s
$('.safe', element).parents(element).show();
Horen was right, it is indeed impossible to show parts of a hidden element.
To make only parts of the text disappear, the non-safe content must be labeled for removal.
$(element).contents().each(function() {
if (this.nodeType == 3)
$(this).wrap('<span class="disappear" />');
});

Edit: one missing piece of information - I can't use the class selector because there are more divs with the same class. I already thought of that, but I forgot to mention it. I have no idea why my post got downvoted, but it seems awfully silly considering I provided a lot of information, gave it honest effort, and tried to be verbose with code examples. People on this forum are ridiculous sometimes.
I'm trying to set the id of a div that doesn't have one and there's no way I can give it one upon generation of the page. I've tried using jquery (.each, .contains, .find, .filter, etc.) and I can't seem to get it right. I know a ton of people have asked this question, but none of the answers made sense to me.
I have the ability to set the text (html?) of the div, but nothing else. It ends up looking like this:
<div class="dhxform_note" style="width: 300px;">Remaining letters: 500</div>
I want a handle to the div object so I can show the user how many more letters they can type by updating the text.
Using this:
$("div")
returns a list of all divs on the page. I can see the target div in the list, but I can't get jquery to return a single object.
I know it can also be done with something like this:
var divs = document.getElementsByTagName("div");
for(var i = 0; i < divs.length; i++) {
if( /^Remaining letters/.test(divs[i].innerText) )
divs[i].id = "kudosMsgNote"
}
}
but I was hoping to complete this with a cleaner looking solution involving jquery. I also simply want to know how to do it with jquery, aesthetics not withstanding.
Use a class selector.
var theDivViaTheClass = $(".dhxform_note");
Class Selector (“.class”)
Description: Selects all elements with the given class.
version added: 1.0
jQuery( ".class" )
class: A class to search for. An
element can have multiple classes; only one of them must match.
For class selectors, jQuery uses JavaScript's native
getElementsByClassName() function if the browser supports it.
You seem to be targeting the <div> by its text. Try using the :contains selector:
$("div").filter(':contains("Remaining letters")').first().attr("id", "kudosMsgNote");
The .first() is to make sure you don't set the same id for multiple elements, in case multiple elements contain the text "Remaining letters".
Here's the docs for the :contains selector: http://api.jquery.com/contains-selector/
Be careful, the text you're looking for is case sensitive when using :contains!
Is that div the only one with the class dhxform_note? If so, you can use the class selector:
$('.dhxform_note').html();
With jQuery, you can specify any css selector to get at the div:
$(".dhxform_note").attr("id", "kudosMsgNote");
will get you this element as well.
Selecting on inner text can be a bit dicey, so I might recommend that if you have control over the rendering of that HTML element, you instead render it like this:
<div name="remainingLetters" class="dhxform_note" style="width: 300px">Remaining Letters: 500</div>
And get it like this:
$("[name=remainingLetters]").attr("id", "kudosMsgNote");
However, it's possible that you really need to select this based on the inner text. In that case, you'll need to do the following:
$("div").each(function() {
if ( /^Remaining letters/.test($(this).html()) ) {
$(this).attr("id", "kudosMsgNote");
}
});
If you cannot set id for whatever reason, I will assume you cannot set class either. Maybe you also don't have the exclusive list of classes there could be. If all those assumptions really apply, then you can consider down your path, otherwise please use class selector.
With that said:
$("div").filter(function() {
return /^Remaining letters/.test($(this).text())
}).attr('id', 'id of your choice');
For situations where there are multiple divs with the class dhxform_note and where you do not know the exact location of said div:
$("div.dhxform_note").each(function(){
var text = $(this).text();
if(/^Remaining letters/.test(text)){
$(this).attr("id", "kudosMsgNote");
}
});
EXAMPLE
If, however, you know that the div will always be the 2nd occurrence of dhxform_note then you can do the following:
$("div.dhxform_note").get(1).id = "kudosMsgNote";
EXAMPLE
Or do a contains search:
$("div.dhxform_note:contains('Remaining letters')").first().attr("id", "kudosMsgNote");
EXAMPLE
This should be basic, but for some reason its not working for me. I just want to store the id when a link that has a certain class is clicked in a variable so as an example:
Some link
I would want jquery to get the id of the link above and store it in a variable. I have tried $this.attr("id") and $this.id, but non of this worked.
This is what I have for the jquery:
$(".only_this_class").click(function() {
var clickedId= $(this).attr("id");
alert(clickedId);
});
I just get "undefined" every time.
I removed the space between this and _class in class="only_this _class" and it is working for me.
Try this here
Please have a look at jQuery Selectors
If you have two classes in your HTML then the syntax is different:
$('.classA.classB')
Have a look at How can I select an element with multiple classes?
NAVEED is right, if you remove the space it works, because if there is a space HTML will put two classes on the element: only_this and _class.
If you are in fact looking for two different classes, you should replace the space with a dot to make it work properly, as in $(".only_this._class")
$(".only_this _class") this selector will look for _class tag in .only_this element. May you are looking for $(".only_this") which will select element which has this class. Try this.
$(".only_this").click(function() {
var clickedId= $(this).attr("id");
alert(clickedId);
});
