jQuery: .parent() wont hide if numerical range begins at 0

问题

I am having some issues with using a numerical range detection within an element, to then hide another element. It seems to work fine when the range starts at 1+, but it breaks at 0+. Their are different iterations of code I have tried, but so far no luck.

This is the website I am trying to use my greasemonkey script on: https://openuserjs.org/?orderBy=updated&orderDir=desc

The purpose: I would like to hide a listed item, if it has 0-100 installs.

Here is my script: https://ghostbin.com/paste/zujku

Here are the three variations of code I have tried using but failed:

$("TR .text-center.td-fit").each(function() { 
if ($(this).text() >= 0 && $(this).text() <= 100){
$(this).parent().hide();
}
});


$(document).ready(function(){
var tds = $("TR .text-center.td-fit").filter(function() {
return (+$(this).text() > 0 && +$(this).text() < 100);
});
tds.parent().hide();
});


$("TR .text-center.td-fit").each(function() { 
if ($(this).text() >= 0 && $(this).text() <= 100){
$(this).parent().hide();
}
});

Note: ".text-center.td-fit" is the 'installs' element on the main list item (TR)

回答1:

Try this:

$("tr.tr-link").each(function() { 
    var num = parseInt($(this).find('td.text-center.td-fit > p').first().text());
    if (num >= 0 && num <= 100) {
        $(this).hide();
    }
});

I used AdBlock element hider in the firefox add-on store to figure this out. With a few combinations/try's, I found this combination to work

AdBlock Element Hider selection:

THEAD + * TD:first-child + .text-center.td-fit > P

Current working version:

$("THEAD + * TD:first-child + .text-center.td-fit > P").each(function() { 
if ($(this).text() >= 0 && $(this).text() <= 70){
    $(this).parent().parent().hide();
    }
});
