我试过以下,但似乎没有用.
var helpIcon = dojo.create("span", {"class":"help-icon", innerHTML:"[?]"}, td1);
var tooltip = new dijit.Tooltip({
connectId: [helpIcon],
label: "large paragraph of text here ... "
});
tooltip._setStyleAttr("max-width: 100px");救命!
我需要选择一个给定其URL的链接节点.使用属性选择器的效果非常好,除了少数几个url有tilda的情况.我无法控制链接网址.这是一个例子:
<script>
dojo.ready(function() {
var node = dojo.query('a[href="http://abc.com/~123"]')[0];
console.debug(node);
node = dojo.query('a[href="http://abc.com/_123"]')[0];
console.debug(node);
});
</script>
...
<body>
<a href="http://abc.com/~123">link 1</a>
<a href="http://abc.com/_123">link 2</a>
</body>
这打印:
undefined
<a href="http://abc.com/_123">
我查看了3级选择器规范,并且没有找到关于属性选择器值(仅仅是CSS字符串)的波形符不支持的任何内容.
救命!
我们是JPA的新手,并试图建立一个非常简单的一对多关系,其中一个叫做Message的pojo可以有一个由连接表定义的整数组id的列表GROUP_ASSOC.这是DDL:
CREATE TABLE "APP"."MESSAGE" (
"MESSAGE_ID" INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1)
);
ALTER TABLE "APP"."MESSAGE" ADD CONSTRAINT "MESSAGE_PK" PRIMARY KEY ("MESSAGE_ID");
CREATE TABLE "APP"."GROUP_ASSOC" (
"GROUP_ID" INTEGER NOT NULL,
"MESSAGE_ID" INTEGER NOT NULL
);
ALTER TABLE "APP"."GROUP_ASSOC" ADD CONSTRAINT "GROUP_ASSOC_PK" PRIMARY KEY ("MESSAGE_ID", "GROUP_ID");
ALTER TABLE "APP"."GROUP_ASSOC" ADD CONSTRAINT "GROUP_ASSOC_FK" FOREIGN KEY ("MESSAGE_ID")
REFERENCES "APP"."MESSAGE" ("MESSAGE_ID");
这是pojo:
@Entity
@Table(name = "MESSAGE")
public class Message {
@Id
@Column(name = "MESSAGE_ID")
@GeneratedValue(strategy …我们需要为div的溢出文本设置垂直滚动条.问题是当我们将高度设置为100%并溢出到auto时,它会扩展到其父容器之外,因为它前面有另一个兄弟div.这是一个例子:
<style type="text/css">
.container {height: 100px; width: 100px; border: solid;}
.titlebar {height: 2em; background: gray;}
.app-body {height: 100%; overflow: auto; background: lightblue;}
</style>
...
<div class="container">
<div class="titlebar"></div>
<div class="app-body">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec condimentum pretium nisl.</div>
</div>app-body设定为100%,则它以具有100像素的高度,这使得它溢出超出的底部container通过2em.我们尝试根本不使用高度app-body但是导致它溢出而没有显示滚动条.
我知道我们可以将高度设置为较小的百分比或固定数量的像素,但如果字体大小改变,这将导致我们的问题.如果高度100% - 2em有效,那么这将是我们试图定义的.
我们正在尝试使用基本的 @OneToMany 关系：
@Entity
@Table(name = "PARENT_MESSAGE")
public class ParentMessage {
@Id
@Column(name = "PARENT_ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer parentId;
@OneToMany(mappedBy="parentMsg",fetch=FetchType.LAZY)
private List childMessages;
public List getChildMessages() {
return this.childMessages;
}
...
}
@Entity
@Table(name = "CHILD_MSG_USER_MAP")
public class ChildMessage {
@Id
@Column(name = "CHILD_ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer childId;
@ManyToOne(optional=false,targetEntity=ParentMessage.class,cascade={CascadeType.REFRESH}, fetch=FetchType.LAZY)
@JoinColumn(name="PARENT_ID")
private ParentMessage parentMsg;
public ParentMessage getParentMsg() {
return parentMsg;
}
...
} ChildMessage child = new ChildMessage();
em.getTransaction().begin();
ParentMessage parentMessage = (ParentMessage) em.find(ParentMessage.class, parentId);
child.setParentMsg(parentMessage); …当我在表格单元格中放置图像后跟文本时,文本的垂直对齐方式与相邻单元格中的文本相比向下移动.我尝试使用line-heightCSS属性,但它似乎没有影响.
在下面的示例中,我需要"123 Description"与"cell one"齐平.此外,默认情况下,图像与"123"之间有一个空格.我怎样才能调整 - 负利润率？
<html>
<head>
<style type="text/css">
table { border-collapse: collapse; }
td { border: thin solid; width: 10em;}
/* .adjust-text { line-height: 1.3em; } */
</style>
</head>
<body>
<table>
<tbody>
<tr>
<td>cell one</td>
<td>
<img src="small-star.png" />
<span class="adjust-text">123 Description</span>
</td>
</tr>
</tbody>
</table>
</body>
</html>我们有一个python程序需要将日志发送到splunk。我们的 splunk 管理员创建了一个服务收集器 HTTP 端点，用于将日志发布到以下位置：
我们找不到在 splunk python SDK客户端中输入 URI 的位置。例如：
import splunklib.client as client
import splunklib.results as results_util
HOST="splunkcollector.hostname.com"
URI="services/collector/raw"
TOKEN="ABCDEFG-8A55-4ABB-HIJK-1A7E6637LMNO"
PORT=443
# Create a Service instance and log in
service = client.connect(
host=HOST,
port=PORT,
token=TOKEN)
# Retrieve the index for the data
myindex = service.indexes["cloud_custodian"]
# Submit an event over HTTP
myindex.submit("Dummy test python client log")
如您所见，我从不使用 URI 变量。上述代码的结果是：
Traceback (most recent call last):
File "splunk_log.py", line 15, in <module>
myindex = service.indexes["cloud_custodian"] …Cordova 8.1.1 (cordova-lib@8.1.0)
