如何在单个jsp页面中访问javascript函数中的jsp数组？

String[] abc[]={"saab","volvo","bmw","Benz","Porsche","Jaguar"};
abc[0]="saab";

Answer 1

您应首先使用例如FlexJson将其序列化为json对象。

您可以将java数组序列化为json数组，该数组应该看起来像

[{item1, item2},{item},{item1,item2}]

使用该方法

String[] temp = ...
StringBuilder builder = new StringBuilder();
builder.append("[");
for(int i = 0 ; i < temp.length ; i++){
    builder.append(temp[i]);
    if(i != temp.length - 1 ){
    builder.append(",");
}
}
builder.append("]");
String jsonArray = builder.toString();

并将其添加到您的请求中;

然后在你的javascript使用

var array = <%= request.getAttribute("temp")%>;

检查是否是

console.log(array);

Answer 2

按字面意思打印它并通过javascript处理它。

背后的场景： jsp-inline代码在服务器端运行。 javasrcript代码在浏览器上运行..

Answer 3

<%  
String[] abc={'saab',' volvo',"bmw","Benz","Porsche","Jaguar"};  
%> 

<script language="JavaScript">  

var jsArr = new Array();  
<%  
for (int i=0; i < abc.length; i++) {  
%>  
jsArr[<%= i %>] = '<%=abc[i] %>';   //Here is the latest update check it sravan .Put single quotes.
<%}%> 
</script>

  function myFunction()
  {
    var select = document.getElementById("dropDownId");

      for ( var i = 0; i < jsArr.length; i++ ){

      var option = document.createElement("option");
      // set the text that displays for the option
       option.innerHTML = status[i];
     // add the option to your select dropdown
       select.appendChild(option);

   }
