Let's say I have 10 buttons. I want to hide all the buttons except the first one. Im trying to accomplish it using each() in jQuery but its not working. Here's my script. This is only a test to see if I can get the index of the buttons. There are no errors appearing. $('button').each(function(index){ alert(index); }); Additional Info: My whole script is this $(function(){ $('div#here').load('test.php'); // This is where all the buttons will come from $('button').each(function(index){ alert(index); }); }); Same as ThiefMaster but don't forget that you need to wait for buttons to be load. You

I'm using Jquery mobile, so ignore some of the following overdone css, its not related to the core issue. I'm having a problem looping over the "Places" in my JSON packet/javascript object. I am getting a response with multiple "Places", but can't seem to figure out how to iterate over them. My 'i' variable in my each loop is working correctly for the first element, and displaying its corresponding name & image. Here's my server side Django view (pretty straight-forward if your unfamiliar with Python): def tonight_mobile(request): callback = request.GET.get('callback', '') def with_rank(rank,

I have an object options : options = {title : 'title1', name : 'name1', url : 'url1', etc.} which is passed in as a parameter to a function. I'm trying to iterate over that object, pass it through another function evaluate , and store the result in another object opts , like so: var opts = new Object(); $.each(options, function(key,value){ opts.key = evaluate(element, value); }); The evaluate(element,value) works fine, but the problem is that opts ends up looking like: {key : eval(element,url1)} instead of {title : eval(element,title1), name : eval(element,name1), etc.} That is, key gets

The following code will not work properly. I've tried different variations & searching everywhere but no luck. i = 1; var timer = new Array(); jQuery('a').each(function($) { i++; timer[i] = setTimeout(jQuery(this).remove(), i * 5000) }) Wrap remove element with a function i = 1; var timer = new Array(); jQuery('a').each(function($) { i++; var thiz = jQuery(this); timer[i] = setTimeout(function() { thiz.remove(); }, i * 5000); }) The first parameter to setTimeout (or setInterval ) needs to be a reference to a function (or a string, but you don't want to use the string syntax). Instead of

Consider the following code: circle.each(function (d) { //...code }); How can I break the loop? Is there a natural D3 way to break out of an each loop? I mean without a flag as follows: var flag = false; circle.each(function (d) { if (flag) return; if (someCondition) flag = true; //...code }); I've tried returning false inside the if statement but it did not work (thought that maybe this would work the same as jquery.each but I was wrong): circle.each(function (d) { if (someCondition) return false; //Not working //...code }); No, there is not. Take a look at the each source code https://github

In the book Eloquent Ruby (page 21, first edition, sixth printing) , the author (Russ Olsen) advocates using the each method instead of the for loop and this is in line with everything I've read elsewhere. However the author also goes on to say that one reason to do so is that the for loop does in fact call the each method, so why not just cut out the middle-man and use each ? So I was wondering how this actually works. To investigate I did do a search on the Ruby repo on github, but was finding it difficult to pinpoint where/how I could see this in action. To restate the question: How can I

I am trying to get the input value in an each loop of a checkbox, i cant figure out how to get this to work, the value keeps outputting as the first checkbox value. $('.custemb, input[name=cb], input[class=multadd]').live("click", function() { $('input[class=multadd]:checked').each(function(index) { val = index + 2; valu = $('input[class=multadd]:checked').val(); multiz = multiz + '&aid' + val + '=' + valu; }); }); the problem is the output of the variable valu is the first checkbox of the overall each loop, not the current checkbox of the loop, i need the current value. Any ideas? You can use

Sematext Monitoring 是最全面的Kafka监视解决方案之一，可捕获约 200个Kafka指标 ，包括Kafka Broker，Producer和Consumer指标。 尽管其中许多指标很有用，但每个人都有一个要监视的特定指标–消费者滞后。 什么是卡夫卡消费者滞后？ 卡夫卡消费者滞后指标表明卡夫卡生产者和消费者之间存在多少滞后。 人们谈论卡夫卡时，通常指的是卡夫卡经纪人。 您可以将Kafka Broker视为Kafka服务器。 代理实际上是存储和提供Kafka消息的对象。 Kafka生产者是将消息写入Kafka（经纪人）的应用程序。 Kafka使用者是从Kafka（Brokers）读取消息的应用程序。 内部经纪人数据存储在一个或多个主题中，每个主题由一个或多个分区组成。 当写入数据时，代理实际上会将其写入特定的分区。 在写入数据时，它会跟踪每个分区中的最后一个“写入位置”。 这称为最新偏移，也称为对数结束偏移。 每个分区都有自己独立的最新偏移量。 就像Broker跟踪每个分区中的写入位置一样，每个Consumer跟踪每个正在消耗其数据的分区中的“读取位置”。 也就是说，它跟踪已读取的数据。 这被称为消费者抵销。 消费者偏移量会定期存在（到ZooKeeper或Kafka本身的特殊主题），因此它可以承受消费者崩溃或不正常关机的情况，并避免重复使用过多的旧数据。
