Comparing two arrays to get the union set. no can do

in Using jQuery • 8 years ago

I've got two lists on a page. I want to hide items in one list when items of the same name (text) are found on a second list. I can create the arrays ok but having difficulty understanding how to use the [i] value as a variable when comparing the two arrays.

The value "Application to Use Radioactive Materials" is in both arrays but my code cannot discern it. I want to hide the tr for "Application to Use Radioactive Materials" on List one because it is a hidden block of text on List two. But the return I'm getting is all items in the second list array (the 'hidden' items) rather than just a single item.

it's this section here that doesn't work for me. could someone please have a look. i'm stuck:

for (var i=0; i < newArr3.length; i++) {

if(jQuery.inArray(i, newArr) >= -1) {

$("p:contains('i')").parent().parent().hide();

} else {

$("#tuke").append("wNOT IN ARRAY xxxxx: " + newArr3[i]);

}

********************************************************************************

here is the fiddle: http://jsfiddle.net/vhabhsrosed/QG8YU/9/

here is the whole block of code:

// SHOW HIDE IRB CHECKLIST

$(document).ready(function () {

var newArr = [];

var xtext = $("i");

$(xtext).each(function (index) {

newArr.push($(this).text())

});

alert("CHECKLIST ARRAY==== " + newArr);

if (jQuery.inArray("Other IRB Site", newArr) != -1) {

// alert("jjjj");

}

var newArr3 = []

var newArr4 = []

var xtext3 = $("A");

var xParent = $("xtext3").parent().parent().parent()

$(xtext3).each(function (index) {

//WHY DOESN'T THIS CONDITION WORK

if ($(this).parent().parent().parent().attr('style') == 'DISPLAY: none') {

newArr3.push($(this).text());

newArr4.push($(this).parent().parent().parent().attr('style'));

}

});

alert("HIDDEN DOCUMENT ARRAY==== " + newArr3)

for (var i=0; i < newArr3.length; i++) {

if(jQuery.inArray(i, newArr) >=1) {

$("#tuke").append("INARRAY " + newArr3[i]);

$("p:contains('i')").parent().parent().hide();

} else {

$("#tuke").append("wNOT IN ARRAY xxxxx: " + newArr3[i]);

}

HERE IS THE HTML:
