我试图使用JSPDF从html生成pdf,html有一个复杂的表格,下面添加了图片.

你可以在这个小提琴中看到,到目前为止我尝试了什么.

pdf.fromHTML(
source, // HTML string or DOM elem ref.
margins.left, // x coord
margins.top, { // y coord
    'width': margins.width, // max width of content on PDF
    'elementHandlers': specialElementHandlers
},

function (dispose) {
    // dispose: object with X, Y of the last line add to the PDF 
    //          this allow the insertion of new lines after html
    pdf.save('Test.pdf');
}, margins);

问题是,当我尝试生成pdf时,我得到了

Uncaught TypeError: Cannot read property 'name' of undefined

是否可以将JSPDF用于这种复杂的表,或者它只适用于简单的表.

编辑: 通过不同的方式解决这个问题,这就是我所做的

1. 我将HTML表格转换为Canvas html2canvas.js
2. 您可以使用canvas获取画布作为Base64图像canvas.toDataURL("image/jpeg" …

这是我的第一个AEM项目,我在一个正在工作的组件中上传图像,如果我打开组件的设置来更改图像,预览不起作用,如下图所示.

cq:对话框横幅文件上传属性

如果我尝试打开图像,/content/xxxDetails/xxx/_jcr_content/par/banner/bannerImage我可以访问图像.

我如何解决预览问题,我认为这是基本问题,但请帮助我,因为这是我的第一个项目.

错误日志

09.05.2017 18:29:15.949 *ERROR* [0:0:0:0:0:0:0:1 …

我在用ng-table.

我试图使用示例中给出的过滤器,但是为了过滤每个列,我需要有单独的文本框.

但我想要实现的是,一个文本框可以根据任何列数据搜索任何行.

我怎样才能实现这一目标？

就像jquery datatable搜索框一样.

我能理解什么是闭包.我可以理解下面的例子.

    def list = ['a','b','c','d']
    def newList = []

    def clos = { it.toUpperCase() }
    list.collect( newList, clos )

assert newList == ["A", "B", "C", "D"]  

我去看了g:选择文档.我在下面看到了.

 <g:select optionKey="id" optionValue="${{it.title?.toUpperCase()}}" name="book.title" from="${bookList}" />

我不明白$ {{it.title？.toUpperCase()}}.

我理解每个对象标题转换为大写的逻辑,但为什么我们需要双"{}"..

为什么使用$ {it.title？.toUpperCase()}无效

我尝试使用inappbrowser登录facebook后回电话.但它无法检查电子邮件,名称等.这是我的代码

Inappbrowser电话

function onDeviceReady(){   
     var my_client_id = FBkey,
     my_redirect_uri = "http://www.fastabuy.com/index.php",
     my_type = "user_agent",
     my_display = "touch";

     var authorize_url = FBgraphapiurl+"/oauth/authorize?";
     authorize_url += "client_id=" + my_client_id;
     authorize_url += "&redirect_uri=" + my_redirect_uri;
     authorize_url += "&display=" + my_display;
     authorize_url += "&scope=publish_stream,email,user_likes";
     isfir = "true";

     var ref = window.open(authorize_url, '_blank', 'location=yes');
     ref.addEventListener('loadstop', function facebookLocChanged() {
         facebookLoc(my_redirect_uri)
     });
}

检查回叫的方法

  function facebookLoc(loc){
     if (loc.indexOf("http://www.fastabuy.com/index.php?") > -1){
       alert(loc.indexOf)
     }
  }

如何检查url何时loc.indexOf>-1关闭inappbrowser.请帮我解决这个问题.

我想选择a标签并在点击时显示其文本.

换句话说,当我点击第一个链接 - "One"时,我想使用显示其文本"One" alert.

当我单击第二个链接 - "示例"时,我想使用显示文本"示例" alert.

<body>
    <div id="tree">
        <ul>
        <li><a target="_blank" href="one.html">One</a></li>
        <li class="folder expnded"><a target="_blank" href="two.html">Examples</a></li>
        </ul>
    </div>    
    <div id="display"></div>    
</body>

更新1:

感谢大家的回答.我真正想要做的是我需要创建一个树结构,当我单击树叶节点时,我必须显示该叶节点的名称.

我使用jQuery DynaTree创建了树结构,但jQuery选择器在上面的代码中对我不起作用.

我无法在标签内选择标签或任何其他元素div.

下面是树形结构:

这是我的完整HTML代码(上面只是一个示例代码)

<html>
<head>
<!-- Include the required JavaScript libraries: -->
<script src="js/jquery-1.7.1.min.js" type="text/javascript"></script>

            <li><a target="_blank" href="">Google</a>
            <li class="folder expnded">Examples …

我正在Android应用程序中搜索推送通知.我查了一下" Pushwoosh ":在initPushwoosh方法我看到了GOOGLE_PROJECT_ID和PUSHWOOSH_APP_ID.

function initPushwoosh() {
  var pushNotification = window.plugins.pushNotification;
  pushNotification.registerDevice(
    {
      projectid: "GOOGLE_PROJECT_ID",
      appid : "PUSHWOOSH_APP_ID"
    },
    function(status) {
      var pushToken = status;
      console.warn('push token: ' + pushToken);
    },
    function(status) {
      console.warn(JSON.stringify(['failed to register ', status]));
    }
  );
  document.addEventListener('push-notification', function(event) {
    var title = event.notification.title;
    var userData = event.notification.userdata;
    if(typeof(userData) != "undefined") {
      console.warn('user data: ' + JSON.stringify(userData));
    }
    navigator.notification.alert(title);
  });
}

我怎样才能获得这两个ID？或者有更好的方法吗？

我在PhoneGap文档中看到了Notification,它是推送通知吗？

谢谢.

在我的sencha应用程序中,当应用程序执行ajax请求时,我想添加加载掩码,并在请求完成后,我需要删除加载掩码.

我尝试下面的代码,但它不适合我

var mask = new Ext.LoadMask(Ext.getBody(), {msg:"Loading..."});

   Ext.Ajax.on('beforerequest', function(){
        mask.show();
   });

   Ext.Ajax.on('requestcomplete', function(){
        mask.hide();
   });

在Grails Web应用程序中,我试图使用rest API将小鸟(指纹)字节数组从applet发布到服务器.

这是我试过的

private String post(String purl,String customerId, byte[] regMin1,byte[] regMin2) throws Exception {
    StringBuilder parameters = new StringBuilder();
    parameters.append("customerId=");
    parameters.append(customerId);
    parameters.append("&regMin1=");
    parameters.append(URLEncoder.encode(new String(regMin1),"UTF-8"));
    parameters.append("&regMin2=");
    parameters.append(URLEncoder.encode(new String(regMin2),"UTF-8"));
    URL url = new URL(purl); 
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();           
    connection.setDoOutput(true);
    connection.setDoInput(true);
    connection.setRequestMethod("POST"); 
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
    connection.setRequestProperty("Content-Length",Integer.toString(parameters.toString().getBytes().length));

    DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
    wr.writeBytes(parameters.toString());
    wr.flush();
    wr.close();
    BufferedReader in = new BufferedReader(new InputStreamReader(
                                connection.getInputStream()));
    StringBuilder builder = new StringBuilder();
    String aux = "";

    while ((aux = in.readLine()) != null) {
        builder.append(aux);
    }
    in.close();
    connection.disconnect(); …
