Unable to change input value after typeahead selection

I have implemented typeahead in 2 inputs in the same page. One works flawlessly, but the other one has an unexpected behaviour. I am able to use TypeAhead only once, and as soon as I select one suggestion, the input field is populated with the correct value, but I am now unable to change it's value. I'll explain: Every key event on the input fires a js error: - Uncaught TypeError: u

无法在键入选择之后更改输入值

我在同一页面中的2个输入中实现了键入。 一个完美的作品,但另一个有一个意想不到的行为。 我只能使用TypeAhead一次,并且一旦我选择了一个建议,输入字段就会填充正确的值,但我现在无法更改它的值。 我会解释一下: 输入上的每个关键事件都会触发js错误: - 未捕获的TypeError:未定义不是函数typeahead.js:944 return (str || "").replace(/^s*/g, "").replace(/s{2,}/g, " "); 然后,一旦输入失去焦点,修改后的值

navigate form fields and edit text with the arrow keys

I have a script in a form of a website, where pressing the enter key or the right arrow changes focus to the next field, or by pressing the Left arrow changes focus to the previous field. I need to be able to use the arrow keys to change the cursor position while editing the text, without change the field focus and only go to the next field when the cursor is at the beginning or end of the text

导航表单域并用箭头键编辑文本

我有一个网站形式的脚本,在此按下回车键或右箭头将焦点更改为下一个字段,或者通过按下左箭头将焦点更改为上一个字段。 我需要能够使用箭头键在编辑文本时更改光标位置,而不必更改字段焦点,只需在光标位于文本的开头或结尾时进入下一个字段。 我怎么能做到这一点? 脚本代码如下所示: function tabulacion_manual(e,adelante,atras,saltar){ if(saltar==1) { setTimeout(function(){ $(ad

Use JavaScript to place cursor at end of text in text input element

什么是最好的方法(我认为最简单的方法)将光标放置在输入文本元素的文本末尾,通过JavaScript - 焦点已设置为元素之后? I faced this same issue (after setting focus through RJS/prototype) in IE. Firefox was already leaving the cursor at the end when there is already a value for the field. IE was forcing the cursor to the beginning of the text. The solution I arrived at is as follows: <input id

使用JavaScript将光标置于文本输入元素中的文本末尾

什么是最好的方法(我认为最简单的方法)将光标放置在输入文本元素的文本末尾,通过JavaScript - 焦点已设置为元素之后? 我在IE中遇到了同样的问题(在通过RJS /原型设置焦点之后)。 当字段已有值时,Firefox已经离开游标。 IE强制光标移动到文本的开头。 我到达的解决方案如下: <input id="search" type="text" value="mycurrtext" size="30" onfocus="this.value = this.value;" name="search"/> 这适

"Scroll" to the very right of a long text input

I have an image selector that allows to choose an image from a gallery, then fills in the URL into a <input type="text"> field. The URLs can be awfully long, and always seeing the first half of the URL in the text field has very little informational value. Does somebody know a way to "scroll" to the very right of the text field so that the end of the URL is visible in

“滚动”到长文本输入的最右侧

我有一个图像选择器,允许从图库中选择图像,然后将URL填入<input type="text">字段。 网址可能非常长,并且始终在文本字段中查看网址的前半部分的信息值非常少。 有人知道一种方法来“滚动”到文本字段的右侧,以便URL的末尾可见而不是开头? 不诉诸于textarea。 除IE6-8 / Opera之外的所有浏览器 在明确设置focus()后,将HTMLInputElement.setSelectionRange()设置为输入值的长度。 缺点是它一旦模糊就

Javascript generic clone() method used in GWT application

I was trying to write a generic clone function which should be able to do true deep cloning. I have come across this link, How to Deep clone in javascript and took the function from there. That code workds pretty well when I try using direct Javascript. I did minor modifications in the code and tried to put in the JSNI code in GWT. clone function: deepCopy = function(item) { if (!item)

GWT应用程序中使用的Javascript通用clone()方法

我试图写一个通用的克隆函数,它应该能够做到真正的深度克隆。 我遇到了这个链接,如何在JavaScript中进行深度克隆,并从那里获取功能。 当我尝试使用直接的Javascript时,该代码工作得很好。 我在代码中做了小的修改,并尝试在GWT中放入JSNI代码。 克隆功能: deepCopy = function(item) { if (!item) { return item; } // null, undefined values check var types = [ Number, String, Boolean ],

Chrome v23 didn't support viewport scale or viewport meta tag?

I made a HTML5 Webapp and I want it auto scaled by window size on PC (not mobile). so I add it in css: @-ms-viewport { width: 1024px; } @-webkit-viewport { width: 1024px; } @-moz-viewport { width: 1024px; } @-o-viewport { width: 1024px; } @viewport { width: 1024px; } In IE10(Win8), It OK, if window is resized smaller, everything in html is smaller. the html has scaled down. but In Chrome v2

Chrome v23不支持视口缩放或视口元标记?

我制作了一个HTML5 Web应用程序,我希望它可以通过PC上的窗口大小自动缩放(而不是移动)。 所以我在css中添加它: @-ms-viewport { width: 1024px; } @-webkit-viewport { width: 1024px; } @-moz-viewport { width: 1024px; } @-o-viewport { width: 1024px; } @viewport { width: 1024px; } 在IE10(Win8)中,它可以,如果窗口的大小更小,则html中的所有内容都会更小。 该html已缩小。 但在Chrome v23中,如果窗口大

how to integrate the two?

I have a very simple Django app that lets users submit a form and see a filtered list of holidays, based on country, duration and price. I would like to use Backbone in the front-end, so that users with JS enabled don't need to GET to see results, but can load them dynamically. I want to use progressive enhancement, so that users with JS get the Backbone experience, and users without JS c

如何整合这两个?

我有一个非常简单的Django应用程序,它可以让用户提交一个表单并根据国家,持续时间和价格查看过滤的假期列表。 我想在前端使用Backbone,以便启用了JS的用户不需要GET即可查看结果,但可以动态加载它们。 我想使用渐进式增强功能,以便JS用户获得Backbone体验,而没有JS的用户仍然可以使用该表单。 我也想遵循DRY原则。 我的问题是如何最好地做到这一点。 有没有使用这两者一起使用最少重复的例子? 我特别想到: 路

Google Analytics for short urls

In javascript, I am trying to access analytics data for google shorten urls, for example. I tired 'URL Shortener API', which worked fine and I received data. But this data doesn't have analytics report for each hour in the day or for each day in the month, as its available on here. Here in response it have some properties for example 'clicks' and 'buckets' which con

Google Analytics for short urls

例如,在JavaScript中,我试图访问Google缩短网址的分析数据。 我厌倦了'URL Shortener API',这工作得很好,我收到了数据。 但是,这些数据并没有每天每小时的分析报告,也没有每月的每日分析报告,因为它可以在这里找到。 在这里作为回应,它有一些属性,例如包含我需要的点击次数的'点击'和'桶'。 检查下面的图片: 但是这些属性在我用'shortener API'收到的数据中不可用。 为此,我

JavaScript naming conventions

I know there is a lot of controversy (maybe not controversy, but arguments at least) about which naming convention is the best for JavaScript. How do you name your variables, functions, objects and such? I'll leave my own thoughts on this out, as I haven't been doing JS for long (couple of years, only), and I just got a request to create a document with naming conventions to be used i

JavaScript命名约定

我知道有很多争议(可能没有争议,但至少有争论)关于哪种命名约定最适合JavaScript。 你如何命名你的变量,函数,对象等? 我将自己的想法留在这里,因为我没有长期从事JS(仅仅是几年),而且我刚刚收到一个请求,要求创建一个命名约定的文档,以便在我们的项目中使用。 所以我一直在寻找(谷歌),有很多不同的意见。 我读过的关于JS的书本身也使用不同的命名约定,但他们都同意一点:“找到适合你的东西并坚持下去。”
