I have created the javascript based demonstration and now I want to hide an image on click in certain condition only.
$("#clear").click(function(){
if ($('#image').is(":visible") && ('#image2').is("hidden")) {
$("#image").hide();
};
});
As you can see my code is not right, so I want to know how to format my code properly. I couldn't find the right way to write multiple conditions in one string. Thanks in advance.
The problem is that you forget to add $ (jQuery) to your second condition and selector hidden is incorrect, should be :hidden:
if ($('#image').is(":visible") && $('#image2').is(":hidden"))

I have a html page with <html> tag where I want to add dir="rtl" and lang="ar" attributes using jQuery when user click on arabic language in drop-down.
I tried using $(html).attr("dir","rtl")
But it returns undefined. Can somebody help as I'm new to jQuery
There is an error on your code, the "html" tag should be written with quotes as folows:
$('html').attr("dir","rtl")

Well, I know this question has been asked before a few times but I'm just a beginner and still couldn't solve it.
I want to set the minimum date of the input date picker to today. In many answers I found the datepicker() method but my webstorm doesn't know this method.
my code:
$("#date").datepicker("option","minDate", new Date(2020,6,5) );
Any tipps for me? Thanks a lot.
Without thinking much about it, it's most likely because you didn't include jQuery UI. datepicker() is a jQuery UI only method.

In an app I'm working on, I'd found that updating the DOM by rewriting a new value to innerHTML doesn't give the expected result.
I typed the following command in the DevTools console:
document.querySelector('main-app').shadowRoot.querySelector('.unitslist').innerHTML = '<unit-bar>1</unti-bar><unit-bar>2</unti-bar>'
With the following result:
<unit-bar>1<unit-bar>2</unit-bar></unit-bar>
You have a typo in your strings. You open with <unit-bar>, but close with </unti-bar>. The closing tags are therefore probably ignored by the browser and it guesses where they should be, resulting in the difference you see.
so , you can solve to avoid overwriting: -
1. get the content of the div and that add the current value to update and the existing values
DOMElem.innerHTML = DOMElem.value + (value to be updated)

I'm trying to select a class inside div.
my code:
<div id="cool" style="width: 80%;height: 80%;margin: auto;">
cool
</div>
Selector:
$('#cool .redirect').attr('href', google.com);
it does not work. Please suggest.
I'm a beginner and just started to learn jquery!
Your code works for me once I correct your attempt to use google.com (that is, the value of the field named com in the nonexistent variable google). Put quotation marks around the string and it works fine.

i am trying to check what items are in array.
this is my code
var fruits=['banana','orange','lemon'];
fruits.splice(0,1,'apple');
for (i=0;i<=fruit.length;i++)
{
alert('The fruits are' + fruits[i]);
};
Somehow it's not Working.
please tell me where i am doing wrong.
thanks.
Have you mistakenly added fruit.length or you have written code like this?
syntax;-
array.splice(index,howmany,item1,.....,itemX)
index->positon from/to u want to ad and remove items
howmany->how many item u want add/remove
item->item list(for more than pne seprate it by comma)
also:-
please add s after fruit in for loop
