I have this into my loop:
var part=[];
part[index]={
title: index
};
And this code generates this:
1: 1
But excepts this
0: 0
1: 1
What the heck?
Zero index is just missing here.
I am working with jQuery .each loop, maybe it's jQuery bug? I tried 1.10.2 and 2.1.1 versions.
Each time you initializing var part=[] that it will make the array empty . Only the last value will be inside it . So initialize before the .each method , not inside in it .

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 have data and when I show with sintax console.log(this.state.product) the data show correctly, here the output in console:
now I want to get harga produk from the output, I use this sintax console.log(this.state.product.harga.produk) but I get the error, how to do that? I want to get data that marked red line
it's because your this.state.product still empty (default state declared in constructor).
before console.log make sure this.state.product is filled with the required data.
so you have to turn it into something like this in rendering
if (this.state.product.status && this.state.product.status ==200) {
console.log(this.state.product.data.harga)
}

I tried to use :first:
$(function(){
$('.awardDltBtn:first').remove();
});
to select the first matched element but it doesn't work in my case.
HTML:
<section>
</section>
I also tried first-of-type and nth-of-type.
First of all you need to include jquery for using jquery code. Then your code is fine for removing the delete button. if you want to remove the complete row associated with that then use:
$('.awardDltBtn:first').prevAll().addBack().remove();

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

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"))
