Select all images on Pinterest for moving to another board

UPDATE: (2015-10-16) [SOLVED!] -- Fixed with trigger() and by limiting to 50 pins with slice(). Many thanks to Abhas Tandon who offered that by using $(this).trigger('click'); instead of $(this).addClass('selected'); it will correctly select the images. I tested with a board consisting of 21 images and it worked perfect! However when trying to move 300+ pins, it failed with this error: "

How to sequentially load images from an AJAX call [Web Development]?

I have a real estate application that display homes. I use AJAX to populate a fixed height/width DIV "window" with home listings. Many times, the DIV window can be populated with literally a 1,000 or so house listings. Each house listing includes one picture of the property and each house listing is about 100px tall (each "row" is 100px tall). Since my DIV height is on

如何从AJAX调用顺序加载图像[Web Development]?

我有一个显示房屋的房地产应用程序。 我使用AJAX来填充具有家庭列表的固定高度/宽度DIV“窗口”。 很多时候,DIV窗口可以填充1000个左右的房产列表。 每个房产列表包括一张房产图片,每栋房屋的高度约为100px(每排“100”高)。 由于我的DIV高度只有400px高,因此在任何给定时间只有4个房屋列表(可能有数千个)可以在不滚动的情况下看到。 题: 我如何按照我在DIV窗口中列出的顺序加载图像。 这样,首先下载可见的房

How to protect widgets from forged requests

Lets say you have a JavaScript widget which needs to fire off a request to your web application if and only if the user wants to click on it. You don't want this request to be vulnerable to CSRF so you write an iframe to the page. Based on the origin inheritance rules the parent site won't be able to read the CSRF token. However what about clickjacking (or likejacking )? Because of CS

如何保护小部件免受伪造请求

假设您有一个JavaScript小部件,当且仅当用户想点击它时,才需要向Web应用程序发出请求。 您不希望此请求容易受到CSRF攻击,因此您需要为页面编写iframe。 根据原点继承规则,父网站将无法读取CSRF令牌。 然而,点击劫持(或劫持)呢? 由于CSRF,您必须位于iframe中,并且x框架选项无法提供帮助,帧同步器也适用。 攻击者将在小部件加载后将一个SVG掩码应用于iframe。 这个掩码将使iframe不可见。 此时攻击者可以将ifra

Is it possible to remove a bottom border on input textfield, under the new char?

I just received this visual design: CLG is a label tag, while the line is an input type=tel Just ignore the purple overlay... The designer asks me to remove the border as the user types a new number. Is that possible? It is definitely possible, however it includes JavaScript (for checking the current input size) Flexbox (for auto-shrinking the border) The idea is basically to mimick

Meteor: async update subscription

I have a subscription that, after calling ready() , performs a number of updates pulling data from other collections: Meteor.publish('foo', function() { this.ready() // Several times: var extraData = OtherCollection.findOne(...) this.changed(..., extraData) }) How can I run these updates asynchronously? Each update accesses the database, does some computation, and calls changed on the

我有一个订阅,在调用ready() ,会执行大量更新从其他集合中提取数据: Meteor.publish('foo', function() { this.ready() // Several times: var extraData = OtherCollection.findOne(...) this.changed(..., extraData) }) 我怎样才能异步运行这些更新? 每个更新访问数据库,进行一些计算,并且changed订阅上的调用。 我还需要在所有更新完成(重新同步)后运行代码。 只需保存发布处理程序并稍后使用它! v

Convert RGB to RGBA over white

I have a hex color, eg #F4F8FB (or rgb(244, 248, 251) ) that I want converted into an as-transparent-as-possible rgba color (when displayed over white). Make sense? I'm looking for an algorithm, or at least idea of an algorithm for how to do so. For Example: rgb( 128, 128, 255 ) --> rgba( 0, 0, 255, .5 ) rgb( 152, 177, 202 ) --> rgba( 50, 100, 150, .5 ) // can be better(lowe
