- (function() {
- //localStorage.clear();
- // Parse the JSON stored in allEntries
- var existingEntries = JSON.parse(localStorage.getItem("allEntries"));
- if(existingEntries == null) existingEntries = [];
- var entry = $(".entry").text();
- localStorage.setItem("entry", JSON.stringify(entry));
- // Save allEntries back to local storage
- existingEntries.push(entry);
- localStorage.setItem("allEntries", JSON.stringify(existingEntries));
- })();
- How can I go about stopping the addition of a localStorage item if it already exists?
- I had this snippet in the code but wasnt working.
- var getAll = JSON.parse(localStorage.getItem("existingEntries"));for(var i = 0; i < getAll.length; i++){//console.log(getAll[i]);//var x = getAll[i];if (entry == x){//then dont setItem}}
this is the only html:- <span class="entry">hello</span>

I have rows that I am trying to remove, then auto-open a link on the row that is then in the first spot. The problem is its opening the link thats in the first row that I removed- like its still there.
Does remove actually remove? It seems like it is not actually removing.// if row contains any keywords in array then remove row (array here) var o; var goodlen = good.length; for(o = 0; o < goodlen; o++){ var x = good[o]; $("span:contains('"+ x +"')").closest("div").remove(); //-------auto open link in current top row--------- var slug = $('.class')eq(0).attr('href'); if(slug){ window.location = "https://xzxz.com" + slug;}After removing unwanted rows how do I target the link on the NOW top row?- var good = [
- "Label1",
- "Label2",
- "Label3"
- ];
- var goodlen = good.length;
- var i;
- var x = good[i];
- for(i = 0; i < goodlen; i++){
- $("span:contains('"+ x +"')").hide();
- }
- <span class='xxx'>Label1</span>
- <span class='xxx'>Label2</span>
- <span class='xxx'>Label3</span>
- I cant tell whats wrong here. I actually had it working and now Im not sure what happened. I cant figure out what the correct syntax is of putting the x variable inside the jquery line. if you look I have it with double quotes inside single quotes --just the + x + part I mean. Which I think is really odd but yet it changes to look correct(coloring) inside my editor. I checked stackoverflow and seen it done this way. This has me baffled. Any suggestions?
- Is it possible to do: if first word in #title appears anywhere in #content than change color of #title to green? I tried an if statement but Im not sure whats going on there. Also im trying it with one line of jquery but Im getting lost in the stacking of methods/selectors. I doubt I can do it with just one line of jquery.
- <p id='title'>
- paragraph
- </p>
- <p id='content'>
- this is a paragraph
- </p>
- $("#content * :contains(#title.text())").css('color','green');
- //---OR---
- //(below I'm only trying to see if I can atleast get x and z to return true- which I cannot.)
- var x = $('#title').text();
- var z = 'paragraph';
- if (x === z){
- alert(x);
- };

Im doing a task that I need to go to a url with an article on it. Count words,img and videos in the main article only. PLUS get video duration. The article page is different every time so I need to first guess which tags are it.I was thinking the logic would be. Find content between each tag. Whichever innerhtml has the most characters in it thats the main article. So count words,img,and videos between those 2 tags. get video duration-i dunno. Is all this even possible?- <p>ABC</p>
- <p>ABCDEF</p>
- <p>ASŞLDKASDA</p>
- <p>asdlkajsdmmlksadma</p>
- <p>aslkdjasldkjsaldkjasdlaksjdlak</p>
- <div id="result"></div>
- ----------------------------------------------------------------
- var $most = $("p").first();
- $("p").each(function(){
- if($most != null && $(this).text().length > $most.text().length){
- $most = $(this);
- }
- });
- $most.addClass("longest");
How can I use this to go through every tag? I tried using '*' and '*', 'body' but it changes css bg black for everything.- Im using pyperclip in python to send contents of txt file to my clipboard. theres five lines of text. I then go to my browser and I want to take those five lines and paste into 5 input boxes using JQuery. 1st line to 1st input box, 2nd line to 2nd...etc with a bind 'paste'.I looked at jakecigar 's code for doing this but it assumes inputs are stacked beside one another and it doesnt work on my input boxes. (Jakes code) Also I think these inputs are 'hidden', but I can target them in console.A side note- I get these  in the first line of the contents being copied to my cboard using pyperclip. My txt file is saved as UTF-8 using 'r' to open file. I know this is python Im talking about now but hey why not mention it? :) Whats with that? I cant paste any html here now. That task is no longer posted.

Im trying to run contains() method twice. Also using next() method. I dont know the proper way to do that.I have elements I want to target but they only have b tags around them. Like 'Price:', beside that could be '$2'. If does NOT have '$2' then hide() those elements. (so only $2 prices are shown.)--Find b tags that are next to the b tag with "price"(which would hold the actual dollar amount)--WORKS- $('b:contains("price")').next();
--Hides all of them - WORKS- $('b:contains("price")').next().hide();
--Does not work- $('b:contains("price")').next(:not(:contains("$6."))');
--Returns 'Undefined'error but DOES contain the variables when I type XX into console- var XX = $('b:contains("price")').next();
--So I try to use contains() with the variable XX...Does not work- $('XX:contains("$6.")').hide();
