I have a problem with define a second class in one Var
Here is the Code: http://jsfiddle.net/2DuQc/
How can I make work this fine?
It's written in JQuery!
var animateEye = $('.rightEye, .leftEye');
doesnt work!
Actually your code won't work because you are overwriting your variabile with only one selector .leftEye so the .rightEye will not have nothing attached to it.
You can use a multiple selector than loop through the result using jQuery each and apply yuor current code.
Use the same class as inner element and find it as a children of the current element.
Code:
$('.rightEye, .leftEye').each(function () {
var animateEye = $(this);
var eyes = animateEye.find(".Eye");
Demo: http://jsfiddle.net/IrvinDominin/rU9E2/
var animateEye = $('.rightEye, .leftEye');
This will give you an array of items, so when you call, say, animateEye.offset(), which one is it supposed to choose? It'll bomb out.
Your current code:
var animateEye = $('.rightEye');
var eyes = $(".Eye");
var animateEye = $('.leftEye');
This will obviously always use .leftEye.
My suggestion? Loop through rightEye and leftEye like so:
var eyes = $('.rightEye, .leftEye');
for(var i = 0; i < eyes.length; i++) {
var animateEye = eyes[i];
}

I am working on a project and I am supposed to add a new element to the top of a table, right now the new element is getting added according to the preexisting order. Can anyone at least tell me what this function is doing?
$.fn.addCellInfoActionItem = function(nRow, aData, iDisplayIndex ) {
rows.push(nRow);
var isEditable = aData[0];
var isStatusEditable = aData[1];
var moduleId = aData[3];
var dueDateOverDue = aData[4];
var aimManaged = aData[5];
var isLastResponseEditable = aData[6];
var readOnlyToolTipText = aData[8];
var actionItemId = aData[10];
var actionItemstatus = aData[14];
var parenttr = $(nRow).closest('tr')[0];
var rowCellObjs = datatable.fnGetTds(parenttr);
var settingSize = datatable.dataTableSettings.length;
var headerCols;
You mean a function like table.push(e), but putting e at 0 index ?
try this :
table=[e].concat(table)
That function is not complete.. what is it doing in the missing code? But it seems it's a "preparing work" for what is there. Variable initializations and a adding of a element to a array.
You can use jquery's prepend() and append() to do dom-manipulations and to add e.g. like in your case a row (dom-element) wherever you exactly want..
See here:
http://api.jquery.com/prepend/
There it says:
The .prepend() method inserts the specified content as the first child
of each element in the jQuery collection (To insert it as the last
child, use .append()
What I am trying to do is rewrite content on the page depending on which object I have selected. I have some objects like so:
function floorPlan(name,rev,sqft,bedrm,bthrm) {
this.name = name;
this.rev = rev;
this.sqft = sqft;
this.bedrm = bedrm;
this.bthrm = bthrm;
}
// 1BR Plans
var a1 = new floorPlan('A1',false,557,1,1);
var a2 = new floorPlan('A2',false,652,1,1);
var a3 = new floorPlan('A3',false,654,1,1);
var a4 = new floorPlan('A4',false,705,1,1);
var a5 = new floorPlan('A5',false,788,1,1);
// The Selected plan
var currentPlan = floorPlan.a1;
I am having the user control this via a .click() function in a menu:
$('.sideNav li').click(function() {
// Define the currentPlan
var current = $(this).attr('id');
var currentPlan = floorPlan.current;
});
The problem is that currentPlan keeps coming back as undefined and I have no idea why. Should I be defining currentPlan differently? I can't seem to find any resources to help me find the answer.
UPDATED:
I switched out a few parts per your suggestions:
// The Selected plan
var currentPlan = a1;
and....
// Define the currentPlan
var current = $(this).attr('id');
currentPlan = current;
However, everything is still returning undefined in the click function (not initially though).
First of all $('this') should be $(this)
Secondly you're trying to use a read ID from your LI as a variable name. That doesn't work. If you store your plans in an array you can use the ID to search in that array:
var plans=Array();
plans["a1"]=new floorPlan('A1',false,557,1,1);
plans["a2"]=new floorPlan('A2',false,652,1,1);
Then your jQuery code should be altered to this:
$('.sideNav li').click(function() {
// Define the currentPlan
var current = $(this).attr('id');
var currentPlan = plans[current];
alert(currentPlan);
});
I created a JSFiddle for this. Is this what you were looking for?
Use as floorPlan.currentPlan = a1;
instead of var currentPlan = floorPlan.a1;
Please create a plunker and will correct if any issue.
I spot two errors.
When you write var inside a function, that variable is only accessible with that function. Right now you are creating a new variable in your anonymous function that is "hiding" the global variable with the same name.
So, first remove the var keyword from the assignment in the anonymous function (the one you call on "click").
Secondly I think you mean to assign floorPlan[current].
The final line should read:
currentPlan = floorPlan[current];
Hi all i am trying to change the html of an object from an array of htmls. But i am having problem iterating properly. I managed to make it work once
EDIT
After a few complains about the clarity of my question I will rephrase it. I have a div panel called .trpanel and a button called #trigger2 (it is a next button). Then I have a series of divs with texts that contain translations. I want when I press the button (called next) to cycle through the translations one by one on the trpanel.
var ltranslation = [];
ltranslation[0] = $("#translation-en-1").html();
ltranslation[1] = $("#translation-ur-en").html();
ltranslation[2] = $("#translation-fr-en").html();
ltranslation[3] = $("#translation-it-en").html();
ltranslation[4] = $("#translation-sp-en").html();
ltranslation[5] = $("#translation-po-en").html();
ltranslation[6] = $("#translation-fr-en").html();
ltranslation[7] = $("#translation-de-en").html();
var l= ltranslation;
$("#trigger2").off('click').on('click',function(){
for (var i = 0; i <= ltranslation.length; i++){
if (i==7){i=0;}
$(".trpanel").html.ltranslation[i]; or ???//replace().ltranslation[]+i??? the code throws errors
}
});
I am quite new to Javascript and i am getting a bit confused with the types of objects and arrays and loops. I managed once to add the htmls but without replacing them ... so they all came one after the other. The i tried to change the code and it hasn't worked since. Any help will be greatly appreciated.
A lot of guessing, but seems like you are trying to do this :
var trans = $('[id^="translation-"]'),
idx = 0;
$("#trigger2").on('click',function(){
$(".trpanel").html( trans.eq(idx).html() );
idx = idx > 6 ? 0 : idx+1;
});
FIDDLE
I think you are trying to do this:
if (i == 7) {
i = 0; // I don't really know why you are doing this, but it will reset the loop
}
$(".trpanel").html(ltranslation[i]); //I'm passing ltranslation[i] to the html method. Instead of .html.ltranslation[i].
}
Also, without seeing any html, I'm not sure but I think you may want to iterate over .trpanel ?
Something like:
$(".trpanel").eq(i).html(ltranslation[i]);
Another thing (so you can make your code clearer I think). You can abstract the array population in a function, like this:
var ltranslation = [];
var languages = ["en-1", "ur-en", "fr-en", "it-en", "sp-en", "po-en", "fr-en", "de-en"];
$.each(languages, function(index) {
ltranslation[index] = $("#translation-" + this).html();
});
// Then you can use ltranslation
If you want to flip through several translations I would implement it that way:
var translations=["hej","hello", "hallo","hoy"];
var showTranslation=function(){
var current=0;
var len=translations.length;
return function(){
var direction=1;
if (current>=len) current=0;
$("#text").text(translations[current]);
current+=direction;
}
}();
$("#butt").on("click", showTranslation);
Fiddle: http://jsfiddle.net/Xr9fz/
Further: You should give your translations a class, so you could easily grab all of them with a single line:
$(".translation).each(function(index,value){ ltranslation.push(value); })
From the question : I managed once to add the htmls but without replacing them -
I think you want to add all of these items into $(".trpanel"). First, dont take the HTML of each element, clone the element itself :
//method ripped from Nico's answer.
var ltranslation = [];
var languages = ["en-1", "ur-en", "fr-en", "it-en", "sp-en", "po-en", "fr-en", "de-en"];
$.each(languages, function(index) {
ltranslation[index] = $("#translation-" + this).clone();
});
Then you could append everything into the container, so add the htmls but without replacing them. append takes in an array without replacing the previous html.
$("#trigger2").off('click').on('click',function() {
$(".trpanel").append(ltranslation);
});
I don't know what exactly you're tring to do, but I've put comments in your code to help you better understand what your code is doing. The net effect of your code is this (which I doubt you want) :
$("#trigger2").off('click').on('click',function(){
$(".trpanel").html(ltranslation[7]);
});
This is your code with some comments and minor changes
var ltranslation = [];
ltranslation[0] = $("#translation-en-1").html();
ltranslation[1] = $("#translation-ur-en").html();
ltranslation[2] = $("#translation-fr-en").html();
ltranslation[3] = $("#translation-it-en").html();
ltranslation[4] = $("#translation-sp-en").html();
ltranslation[5] = $("#translation-po-en").html();
ltranslation[6] = $("#translation-fr-en").html();
ltranslation[7] = $("#translation-de-en").html();
var l= ltranslation;
$("#trigger2").off('click').on('click',function(){
for (var i = 0; i < ltranslation.length; i++){
//if (i==7){i=0;} <-- This will cause an infinite loop won't it? are you trying to reset i? i will reset next time loop is called,
$(".trpanel").html(ltranslation[i]); //<-- this will overwrite elements with class .trpanel ltranslation.length times...
///you'll see only the value of translation[7] in the end
}
});
EDIT
To do what you want to do based on your comments, try this:
var ltranslation = [];
ltranslation[0] = $("#translation-en-1").html();
ltranslation[1] = $("#translation-ur-en").html();
ltranslation[2] = $("#translation-fr-en").html();
ltranslation[3] = $("#translation-it-en").html();
ltranslation[4] = $("#translation-sp-en").html();
ltranslation[5] = $("#translation-po-en").html();
ltranslation[6] = $("#translation-fr-en").html();
ltranslation[7] = $("#translation-de-en").html();
var counter = 0;//a global counter variable
$("#trigger2").click(function(){ //eeverytime button is clicked do this
$(".trpanel").html(ltranslation[counter]); //set the html to an element of array
counter++; //increment counter
if(counter==ltranslation.length) //reset the counter if its bigger than array len
counter=0;
});
I'm trying to load X amount of <li>'s into a <ul> via a for loop in a jquery function, and while I think I've got the syntax about right I'm not getting anything loading. (no problem with loading a single <li>, but none for multiples with the method I've tried)
Initially I attempted to pass a variable into the loop to determine the amount of increments: var peekListAmount = 5;
That didn't work so I went for a bog-standard loop incrementer. That doesn't work either so, after searching here and getting close, I have put together a fiddle to see if someone can point out what I'm doing wrong: http://jsfiddle.net/janowicz/hEjxP/8/
Ultimately I want to use Knockout.js to dynamically input a number to pass to the loop amount variable, but 1st things 1st.
Many thanks in advance.
When you do:
var peekListItem = $('<li>...</li>');
you're creating a single instance of an <li> node, encapsulated in a jQuery object.
Appending an already-present node to the DOM just removes it from its current place in the DOM tree, and moves it to the new place.
You need to create the node inside the loop, not outside, otherwise you're just re-appending the same node each time, not a copy of that node.
In fact, given you're not manipulating that node, you can just put the required HTML directly inside the .append() call without wrapping it in $(...) at all:
$(function() {
var peekList = $('<ul class="peekaboo-list">').appendTo('div.peekaboo-wrap');
function addLiAnchorNodes(nodeAmount) {
var html = '<li>' +
'<p class="peekaboo-text"></p></li>';
for (var i = 0; i < nodeAmount; ++i) {
peekList.append(html);
}
}
addLiAnchorNodes(5);
});
See http://jsfiddle.net/alnitak/8xvbY/
Here is you updated code
$(function(){
var peekList = $('<ul class="peekaboo-list"></ul>');
var peekListItem = '<li><p class="peekaboo-text"></p></li>';
//var peekListAmount = 5;
var tmp = '';
var addLiAnchorNodes = function (nodeAmount){
//var nodeAmount = peekListAmount;
for (var i = 0; i < 10; i++){
tmp += peekListItem;
}
peekList.append(tmp);
$('div.peekaboo-wrap').append(peekList); // This bit works fine
}
addLiAnchorNodes();
});
This should work. Instead of appending the list item in each loop, append the list only once at the end.
$(function(){
var peekList = $('<ul class="peekaboo-list"></ul>');
peekList.appendTo('div.peekaboo-wrap');
var addLiAnchorNodes = function (nodeAmount){
var list = "";
for (var i = 0; i < 10; i++){
list += '<li>Sample<p class="peekaboo-text"></p></li>';
}
peekList.append(list);
}
addLiAnchorNodes();
});
Here is the updated fiddle
Try this:
$(function(){
var peekList = $('<ul class="peekaboo-list"></ul>');
$(peekList).appendTo('div.peekaboo-wrap'); // This bit works fine
var addLiAnchorNodes = function (nodeAmount){
//var nodeAmount = peekListAmount;
for (var i = 0; i < 10; i++){
var peekListItem = $('<li><p class="peekaboo-text"></p></li>');
peekListItem.appendTo(peekList);
}
}
addLiAnchorNodes();
});
I'm trying to turn more into a hyperlink, but it's like it totally ignores the last wrap.
$j('#sub > div[id^="post-"]').each(function() {
var sid=this.id.match(/^post-([0-9]+)$/);
var sfimg = $j(this).find("img");
var sfhh = $j(this).find("h2");
var sfpt = $j(this).find("p:not(:has(img)):eq(0)");
var more = 'more';
$j(this).html(sfimg);
$j(sfimg).wrap($j('<a>').attr('href', '/blog/?p='+sid[1]));
$j(this).append(sfhh).append(sfpt);
$j(sfpt).wrap($j('<div>').attr('class', 'sfentry'));
$j(this).append('<div class="morelink">'+more+'</div>');
$j(more).wrap($j('<a>').attr('href', '/blog/?p='+sid[1]));
});
You over-using the jquery function ($j(), in your case) and your doing things in the wrong order. Also, there may be cases (possibly) that $(this).find('img'), for instance, might return more than one element... Not sure of your scenario, though.
Try this (may not be perfect, but it should lean you in the right direction):
$j('#sub > div[id^="post-"]').each(function() {
var sid = this.id.match(/^post-([0-9]+)$/);
var sfimg = $j(this).find("img");
var sfhh = $j(this).find("h2");
var sfpt = $j(this).find("p:not(:has(img)):eq(0)");
var more = 'more';
sfimg.wrap($j('<a>').attr('href', '/blog/?p='+sid[1]));
$j(this).html(sfimg);
sfpt.wrap($j('<div>').attr('class', 'sfentry'));
// You do realize what you have will append the paragraph to your h2 tag, right?
// I think you want:
/*
$j(this).append(sfhh).end().append(sfpt);
*/
$j(this).append(sfhh).append(sfpt);
$j(this).append('<div class="morelink">'+more+'</div>');
$j('.morelink',this).wrap($j('<a>').attr('href', '/blog/?p='+sid[1]));
});
There were all sorts of crazy things going on in that code. Remember that you need to modify the objects before appending them to another object (unless you have some unique way of identifying them after the fact, i.e. IDs).
Good luck.
Why do you expect $j(more) to match anything?
