我正在使用angularjs datatable并尝试在此页面中使用按钮插件https://l-lin.github.io/angular-datatables/#/withButtons
.withButtons([
'columnsToggle',
'colvis',
'copy',
'pdf',
'excel',
{
text: 'Some button',
key: '1',
action: function (e, dt, node, config) {
alert('Button activated');
}
}
]);
我得到Unknown按钮类型:'columnsToggle'和'colvis',但当我从代码中删除'columnsToggle'和'colvis'时它运行没有任何问题,但除了自定义按钮外不显示其他按钮
{
text: 'Some button',
key: '1',
action: function (e, dt, node, config) {
alert('Button activated');
}
}
复制,pdf,excel没有出现,任何人都可以帮我解决问题吗？
我正在尝试使用 Java ( http://docs.aws.amazon.com/AmazonS3/latest/dev/RetreeringObjectUsingJava.html )获取存储在 Amazon S3 中的文件，但我对对象键有问题，因为我不这样做不知道那是什么。
存储桶名称是testbucket，我在该存储桶中有一个具有该名称的文件夹files。如果我有一个名为image.jpeg;的文件 对象键是什么？
private static String bucketName = "testbucket";
private static String key="files/image.jpeg";
public static void main(String[] args) throws IOException {
AmazonS3 s3Client = new AmazonS3Client(new ProfileCredentialsProvider());
S3Object s3object = s3Client.getObject(new GetObjectRequest(
bucketName, key));
}
我得到这个输出：

以下代码在执行 JavaScript 之前提交表单。
<form:form modelAttribute="api" id="form">
<form:textarea path="text" class="form-control" rows="10" id="redacttext"/>
<button type="submit" class="btn btn-default">Submit</button>

Javascript 函数
function dosomething() {

通过 jquery 执行 javascript 函数
$('#form').submit(function() {
dosomething();
});

所以我使用这段代码
$scope.dtOptions = DTOptionsBuilder.newOptions()
.withOption('ajax', {
dataSrc: function(json) {
conole.log(json)
json['recordsTotal'] =json.length
json['recordsFiltered'] = json.length

我已执行此步骤来修复模块“ AppModule”导入的意外值“ DataTablesModule”。请添加一个@NgModule注释。
1-in tsconfig.json add
"baseUrl": ".",
"paths": {
"@angular/*": [
"node_modules/@angular/*"
]
2-in webpack.comon.js add
plugins: [
new TsConfigPathsPlugin({
configFileName: helpers.root('tsconfig.json'),
compiler: "typescript",

但是得到这个错误
Can't bind to 'dtOptions' since it isn't a known property of 'table'.
谁能帮我解决这个问题？
我有以下javascript对象数组,如果至少有一个对象为true,我需要检查输出属性返回true否则返回false,有人可以帮我实现吗？
var array=[{"id":100,"output":false},{"id":100,"output":false},
{"id":100,"output":true}]
我有以下Javascript对象数组,如果对所有对象都为true,我需要检查输出属性,如果对所有对象输出true则返回true否则返回false,任何人都可以帮我实现吗？
var array=[{"id":100,"output":true},{"id":200,"output":true}]
更新
我已经尝试了这个代码但是如果只有一个输出为真而不是所有输出它会执行打印
function check(){
var data=[{"id":100,"output":false},{"id":200,"output":true}]
data.every(function (e) {
if(e.checked===true){
console.log("print something")
}
});
}
代码有什么问题？
