拉伸png背景图像很容易：
.stretched-logo-bg {
background: url("../img/curve.png") center center no-repeat;
background-size: 100% 100%;
}
但是，这不适用于SVG背景
.stretched-logo-bg {
background: url("../img/curve.svg") center center no-repeat;
background-size: 100% 100%;
}
它不会被拉伸，它将保持其宽高比并保持居中。
至少在Chrome 52中
目前我在很多地方都有：
{% from "macros/render_product_materials.html" import render_product_materials %}
{% from "macros/render_citation.html" import render_citation %}
{% from "macros/render_product_packages.html" import render_product_packages %}
{% from "macros/render_icon_explanation_section.html" import render_icon_explanation_section %}
{% from "macros/render_percentage_items.html" import render_percentage_items %}
这个名单还在继续！
然后我调用模板中的代码：
{{render_percentage_items('some args',2,34,55)}}
如果我改变了一个函数名，我必须到处改变它，如果我添加一个新函数，我必须每次都去导入它
我宁愿这样做，就像这样：
{% include 'macros/all_macros.html' %}
然后我只是把所有的进口 all_macros.html
但是：导入在上下文中不可用
例如
{% include 'macros/all_macros.html' %}
{{render_percentage_items('some args',2,34,55)}}
不起作用。render_percentage_items未找到。现在有什么方法可以用 jinja 方式做到这一点？
好吧,我似乎并不理解某些事情RegExp.有人可以对我有所了解吗？是否有一些隐含的词RegExp导致不匹配？我的假设是子串"slt"包含一些隐藏的绝密詹姆斯邦德标志,这使得RegExp失败.
演示来摆弄: 工作演示
//does not work
var funcArgString="c09__id slt ccc";
var myRegExp = new RegExp("([^ \s]*) ([^ \s]*) ([^ \s]*)","g");
alert(myRegExp.exec(funcArgString));
//works... why???
var funcArgString="c09__id abcdefg ccc";
var myRegExp = new RegExp("([^ \s]*) ([^ \s]*) ([^ \s]*)","g");
alert(myRegExp.exec(funcArgString));
//works as well
var funcArgString="c09__id slt ccc";
var myRegExp = new RegExp("(.*) (.*) (.*)","g");
alert(myRegExp.exec(funcArgString));
来自: andrew whittakers示例,显示自定义jquery自动完成实现中的结果编号
_response: function(contents){
$.ui.autocomplete.prototype._response.apply(this, arguments);
$(this.element).trigger("autocompletesearchcomplete", [contents]);
}
为什么[contents]不contents呢？
我来自这个链接，其中包含有关使用Velocity.js进行svg动画时IE崩溃的问题。
并且意识到，地狱，firefox实际上是在此jsbin中渲染不透明度为0的svg文本。

显然,res.send同步调用,而文件读取异步.这有一个聪明的解决方案吗？我被迫实际传入res吗？

我像这样对齐表格数据
<tr>
<td> first row </td>
<td> second row </td>
<td> third row </td>
</tr>
<tr>
<td> first row </td>
<td> second row </td>
<td> third row </td>
</tr>
现在要修复我想要复制第tr一个旁边的第二个内容的错误并用trs 括起来
例如
<tr>
<td> first row </td> <td> first row </td>
<td> second row </td> <td> second row </td>
<td> third row </td> <td> third row </td>
</tr>
然后手动执行此操作:
<tr><td> first row </td> <td> first row </td> </tr>
<tr> <td> second row </td> <td> second …我在laravel 5.3日志中有这个条目

为什么它会截断一条重要的错误信息？现在我无法弄清楚出了什么问题......
我有这个vue js组件：
<template>
<div>
hello world
</div>
</template>
<script>
export default {
name: 'mycomp',
data: function () {
console.error("window.google_recaptcha_public_key", window.google_recaptcha_public_key);
return {
}
},
mounted() {
let app = this;
console.error("window.google_recaptcha_public_key2", window.google_recaptcha_public_key);
},
}
</script>
<style scoped lang="scss">
</style>
返回：
window.google_recaptcha_public_key undefined
window.google_recaptcha_public_key2 undefined
在哪里可以使所有全局配置轻松自如呢？
注意此配置位于我的laravel后端中。所以我不会将所有值从后端复制粘贴到前端
