Converting a Java ArrayList of strings to a JavaScript array

rated 0 times [ 6] [ 2] / answers: 1 / hits: 86553 / 11 Years ago, wed, july 3, 2013, 12:00:00

In my Java code, I have an ArrayList of Strings. I'd like to put this data in a JavaScript variable on a JSP page I'm working on. My first thought was to include it directly, e.g.:

var myArray = <%= arrayList %>;

Unfortunately, when executed, myArray is a string in the format [a,b,c], not an actual JavaScript array. How do I get some data from a Java ArrayList to a JavaScript array?

When you use <%=arraylist%> it calls the toString() on list and prints [a,b,c]

And No,you cannot direclty convert From Java arrayList to javascript array ,Convert the Java ArrayList to JSON String, and use JSON.parse() to get Javascript object.

Have a look at Json objet and Json in java
