在这个插件我有一个div包含一些文本和一个span文本.
我的目标是改变文本div,而不改变文本span.
我尝试使用jQuery,但问题是整个div文本发生了变化,还取代了span文本,任何想法？
HTML
<div id="id1">some text to change <span>THIS TEXT STAYS</span></div>
使用Javascript:
$( document ).ready(function() {
var id1 = $("#id1");
id1.text("New Text");
});
每当我运行我的应用程序时,activator run我都会收到以下警告:
"The system cannot find the file BIN_DIRECTORY\..\conf\sbtconfig.txt"
这条消息是什么意思？我应该创建这个文件吗？该应用程序工作正常.
我有以下动态创建的Spark数据帧:
val sf1 = StructField("name", StringType, nullable = true)
val sf2 = StructField("sector", StringType, nullable = true)
val sf3 = StructField("age", IntegerType, nullable = true)
val fields = List(sf1,sf2,sf3)
val schema = StructType(fields)
val row1 = Row("Andy","aaa",20)
val row2 = Row("Berta","bbb",30)
val row3 = Row("Joe","ccc",40)
val data = Seq(row1,row2,row3)
val df = spark.createDataFrame(spark.sparkContext.parallelize(data), schema)
df.createOrReplaceTempView("people")
val sqlDF = spark.sql("SELECT * FROM people")
现在,我需要迭代每一行和sqlDF每列打印每一列,这是我的尝试:
sqlDF.foreach { row =>
row.foreach { col => println(col) }
}
row是类型Row,但不可迭代,这就是为什么此代码抛出编译错误 …
在此插件中,目标是基于控制器中的验证(而不是内置插件required或min-length)来显示错误消息.设置ng-message-exp时,不显示消息错误.任何想法如何使这项工作？
HTML
<body ng-app="ngMessagesExample" ng-controller="ctl">
<form name="myForm" novalidate ng-submit="submitForm(myForm)">
<label>
This field is only valid when 'aaa' is entered
<input type="text"
ng-model="data.field1"
name="field1" />
</label>
<div ng-messages="myForm.field1.$error" style="color:red">
<div ng-message-exp="validationError">this is the error</div>
</div>
<br/><br/>
<button style="float:left" type="submit">Submit</button>
</form>
使用Javascript
var app = angular.module('ngMessagesExample', ['ngMessages']);
app.controller('ctl', function ($scope) {
$scope.submitForm = function(form) {
if (form.field1.$modelValue != 'aaa') {
$scope.validationError = true;
console.log('show error');
}
else {
$scope.validationError = false;
console.log('don\'t show error');
}
};
});
我在Play for Scala中有以下代码来访问带有Hibernate的SAP Hana表.我需要用MySql实现相同的代码,但问题是MySql不支持序列(它适用于AUTO_INCREMENT列)和代码中断,因为我必须@SequenceGenerator为Hana 指定.有没有办法编译这个代码,条件是排除@SequenceGenerator注释,所以它同时适用于MySql和Hana？
@Entity
@Table(name = "clients")
class ClientJpa {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "generator")
@SequenceGenerator(name="generator", sequenceName = "cliSeq", allocationSize = 1)
var surrogateKey: Int = _
var code: String = _
var name: String = _
}
在 Angular 中，我需要在新选项卡中打开 PDF，并允许用户使用特定名称下载它（Example.pdf）。下面的代码下载 PDF，但不会打开新选项卡（target=_blank不起作用）。任何想法如何解决这一问题？
show(blob){
var fileURL: any = URL.createObjectURL(blob);
var a = document.createElement("a");
a.href = fileURL;
a.target = '_blank';
a.download = "Example.pdf";
a.click();
}
给出以下代码:
var msg = {
field1: val1,
field2: val2,
// more fields
};
$scope.$broadcast("EventName", msg);
事件使用者收到指向msg或复制的指针？
在这个插件中有一个带有ngMessage验证的表单.这就是我想要实现的目标:
在插件中我有两个问题:(1)在最初显示表单时显示消息,(2)当没有错误消息并且用户点击按钮时,表单未提交.代码有什么问题？
HTML
<form name="myForm" novalidate>
<label>
Enter your name:
<input type="text"
name="myName"
ng-model="name"
ng-minlength="5"
ng-maxlength="20"
required />
</label>
<div ng-messages="myForm.myName.$error" style="color:red" role="alert">
<div ng-message="required">You did not enter a field</div>
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
<button type="submit"
ng-submit="myForm.$valid && submitForm()">Submit</button>
</form>
使用Javascript
var app = angular.module('ngMessagesExample', ['ngMessages']);
app.controller('nameController', function ($scope) {
$scope.submitForm = function() {
alert('Form submitted - fields passed validation');
};
});
在这个插入中我有三个DIVs除以另外两个DIV可拖动的(灰色).当DIV向上/向下或向左/向右拖动可拖动的s时,DIV应调整其他s的大小.
第一个可拖动的DIV工作正常(左侧的那个可以垂直调整其他DIV的大小).但是第二个draggable DIV不起作用,即使该方法与第一个draggable相同DIV.任何想法如何解决这一问题？
使用Javascript
var top1H, bottom1H;
$( "#div1" ).draggable({
axis: "y",
start: function(event, ui) {
shiftInitial = ui.position.top;
top1H = $("#top1").height();
bottom1H = $("#bottom1").height();
},
drag: function(event,ui) {
var shift = ui.position.top;
$("#top1").height(top1H + shift - shiftInitial);
$("#bottom1").height(bottom1H - shift + shiftInitial);
}
});
var right1W, left1W;
$( "#div2" ).draggable({
axis: "y",
start: function(event, ui) {
shiftInitial = ui.position.left;
right1W = $("#right1").height();
left1W = $("#left1").height();
},
drag: …在这个插件中,我有一个带有可拖动标题栏的Angular UI模式.拖动条形图时,整个模态会移动.问题是,如果我相对快速地上下移动鼠标,光标会失去对条的焦点,模态会停止移动.任何想法如何解决这一问题？任何其他方法也欢迎.
