由 别来无恙 提交于 2019-12-09 06:14:34
问题 I can't get rid of unwanted placeholder (or watermark) on password textbox.

Setting an HTML text input box's “default” value. Revert the value when clicking ESC

由 落爺英雄遲暮 提交于 2019-12-09 00:25:47
问题 When a web form is written to the browser, the browsers remembers what the initial values are of a text INPUT box. ie. when it receives HTML like this: <input type="text" value="something"> The browser remembers "something" as the initial/default value. When the user starts typing over it, then hits ESC, the browser reverts the field to the initial value (or blank if it was initially blank of course). However, when creating a text input box programatically, hitting ESC always seems to blank

tensorflow基础-数据类型

由 做~自己de王妃 提交于 2019-12-08 17:01:27
一：tensorflow中的计算定义和执行 首先，对于tensorflow来说，最重要的概念就是图（Graph）和会话（Session），tensorflow的计算思想是：以图的形式来表示模型，表示和计算分隔开。 这就是一个Data Flow Graph，最核心的就是定义和计算不等于执行，一个模型跑起来只需要两步：先描述整幅图，然后在session中执行运算。tensorflow==tensor + flow，tensor是张量，flow流动，可以理解为张量在图中通过上图所示里面的a，b，c，d，e这些运算（ 这里把他们叫做op ）进行流动（传递和变换）。下面通过一个简单的实例看一下： v1 = tf.constant([1,2,3]) v2 = tf.constant([4,5,6]) v3 = tf.add(v1, v2) print(v1) print(v2) print(v3) with tf.Session() as sess: print(sess.run(v3)) 在上面，定义了两个 常量类型的张量 （后面会说）v1、v2，v3把v1、v2相加，然后通缩Seeion执行运算，看一下输出结果： Tensor("Const:0", shape=(3,), dtype=int32) Tensor("Const_1:0", shape=(3,), dtype=int32)

Use Font Awesome (5) icon in input placeholder text

问题 I've come across many ways to solve this using Font Awesome < 5, but I can't seem to solve this in any way using Font Awesome 5. This is how many resources point to adding a Font Awesome icon in placeholder text. <input style="font-family:FontAwesome !important" type="text" placeholder="&#xf167"> 回答1: Remember to not use the general "Font Awesome 5" font family, you need to specifically end with the branch of icons you're working with.

HTML5 placeholder attribute: Chrome doesn't line-wrap in textareas

由 允我心安 提交于 2019-12-08 06:19:20
问题 I'm trying to use a couple of these newfangled HTML5 form attributes, and the placeholder attribute seemed to be a good match to get the magic going. It works pretty good, but Chrome insists to present the whole placeholder text on one line if the textarea is to small. Other browsers like Firefox or rekonq (the only other WebKit browser that I have at my disposal ATM) line-wrap the text. While the spec talks about linefeeds being forbidden in the placeholder attribute, it says nothing against
