小编Rus*_*pez的帖子

所以我有这样的布局:

div {
  border: 1px solid
}

<div id="col_1" style="float:left;width:150px;">1</div>
<div id="col_2" style="float:left;width:100px;">2</div>
<div id="col_3" style="float:left;width:<REMAINING_WIDTH>;">3</div>

col_1和col_2占用固定的空间.我希望第三列能够占用其余部分.完成此任务的最佳方法是什么？

我有一个页眉,内容和页脚.页眉和页脚具有固定的高度,我希望内容调整其高度,以便它在页眉和页脚之间动态匹配.我打算在我的内容中加入背景图像,因此它实际上填满了剩余的未占用垂直空间是至关重要的.

我使用Sticky Footer方法确保页脚保留在页面底部.然而,这不会使内容跨越剩余空间的整个高度.

我尝试了几个涉及我添加的解决方案,height:100%, height:auto; position:relative但它没有用.

html,
body {
  height: 100%;
  background-color: yellow;
}
header {
  width: 100%;
  height: 150px;
  background-color: blue;
}
header nav ul li {
  display: inline;
  padding: 0 30px 0 0;
  float: left;
}
#wrapper {
  min-height: 100%;
  height: auto !important;
  height: 100%;
  margin: 0 0 -30px 0;
  /* the bottom margin is the negative value of the footer's height */
  position: relative;
}
#wrapper #content {
  background-color: pink;
  width: 400px;
  height: …

这是css中的自定义滚动条

 /* Gmail style scrollbar */
 ::-webkit-scrollbar {
   width: 12px
 }
 ::-webkit-scrollbar-thumb {
   border-width: 1px 1px 1px 2px
 }
 ::-webkit-scrollbar-track {
   border-width: 0
 }
 ::-webkit-scrollbar {
   height: 16px;
   overflow: visible;
   width: 16px;
 }
 ::-webkit-scrollbar-button {
   height: 0;
   width: 0;
 }
 ::-webkit-scrollbar-track {
   background-clip: padding-box;
   border: solid transparent;
   border-width: 0 0 0 4px;
 }
 ::-webkit-scrollbar-track:horizontal {
   border-width: 4px 0 0
 }
 ::-webkit-scrollbar-track:hover {
   background-color: rgba(220, 172, 0, .05);
   box-shadow: inset 1px 0 0 rgba(220, 172, 0, .1);
 }
 ::-webkit-scrollbar-track:horizontal:hover {

我在通过终端运行测试时遇到问题。我需要运行 mvn install，但我得到：

我希望Content A,Content B和Content C列水平居中.我有这个代码试图添加

HTML:margin:0 auto to .columns-container,它不起作用.有人可以帮忙吗？

问题:
有没有办法从javascript触发Webkit的自动保存功能？如果不通过专用API,至少有一种方法可以通过操作cookie来实现相同的功能吗？

背景:
我非常喜欢HTML5中新的"搜索"输入类型,并希望为我的Webkit用户提供轻松调用过去搜索的好处,而无需在我的数据库中存储所有这些搜索的开销(使用自动保存功能).

我遇到的问题是,如果搜索输入封装在表单中,并且该表单在提交时执行标准POST,则搜索条件似乎只会被保存.由于我的搜索输入用于过滤已经存在的结果,因此完全重新加载页面没有多大的逻辑意义,因此我使用AJAX来重新填充结果.如果我在我的AJAX函数中返回false,那么界面都是干净且一致的,但是这显然不会触发表格POST [按设计],因此浏览器(至少Chrome)不会保存搜索词.返回true会刷新整个页面,销毁我注入AJAX的内容和过滤器的整个点,但会保存搜索词.

$('#filter-form').submit(function(e) {
      var term = $('#filter').val();
      $.ajax({
        async: true,
        type: 'POST',
        url: '/Home/GetResults',
        data: {
          filter: term
        },
        success: function(returnData) {
          $('#result-list').html(returnData);
        }
      });
      return false;
    }

<form id="filter-form" name="filter-form" action="#">
  <input type="search" name="filter" id="filter" results="5" autosave="EluminitePreviousFilters" />
</form>
<div id="result-list"></div>

我正在尝试使用-webkit-font-smoothingCSS属性控制谷歌浏览器(可怕的)字体抗锯齿,但它对文本完全没有影响.

<div style="font-size: 42px">
  <p style="-webkit-font-smoothing: subpixel-antialiased">This is a font test.</p>
  <p style="-webkit-font-smoothing: antialiased">This is a font test.</p>
  <p style="-webkit-font-smoothing: none">This is a font test.</p>
</div>

我比较了Photoshop中的像素,三者完全相同.Chrome不再支持此属性了吗？

我想DIV在大型和桌面屏幕上放置一个关于bootstrap轮播的内容.请参阅下图以了解您的情况.

在移动和标签屏幕中应该是这样的 -

我不知道如何使用bootstrap 3创建这个布局.希望有人可以帮助我.

我用javascript的工具包dojo将这个简单的表单转换为HTML元素形式:

dojo.require("dijit.form.Form");
dojo.require("dijit.form.ValidationTextBox");
dojo.require("dijit.form.Textarea");
dojo.require("dijit.form.Button");

dojo.addOnLoad(function() {
  var form = new dijit.form.Form({
    method: "POST",
    action: ""
  }, "createCollectionForm");
  var title = new dijit.form.ValidationTextBox({
    required: true,
    trim: true
  }, "title");
  var description = new dijit.form.Textarea({
    trim: true
  }, "description");
  var submit = new dijit.form.Button({
    label: "OK",
    onClick: function(event) {
      dijit.byId("createCollectionForm").submit();
    }
  }, "submit");
});

<link href="http://ajax.googleapis.com/ajax/libs/dojo/1.9.3/dojo/resources/dojo.css" rel="stylesheet" />
<link href="http://ajax.googleapis.com/ajax/libs/dojo/1.9.3/dijit/themes/claro/claro.css" rel="stylesheet" />

    <dd id="title-element">

假设我有以下两个表:

@Entity public class Foo {
   @Id private int id;
   @ManyToOne()
   @JoinColumn(name = "bar_id")
   private Bar bar;
}
@Entity public class Bar {
   @Id private int id;
   private Boolean flag;
}

我想写一个JPQL查询,Bar.flag根据一组Fooid 改变一些值.

如果这是普通的SQL我会写这样的东西:

UPDATE Bar SET flag = true WHERE id IN (SELECT bar_id from FOO where id = 3);

但是,您无法将其转换为JPQL,因为该bar_id列未映射到实体的属性.

由于bar_id没有直接映射到FooEntity,我如何在JPQL中实现这种查询？
