This is the actual code I am using

return "<a href='javascript:void();' onclick='openWindow(" 2 "," + 1 + "," + 4326 + "," + symbolurl + ");'>Edit Asset Info</a>";

Answer 1

URL地址是一个字符串，因此您应该用引号括起来：

... onclick="openWindow(2,1,4326,'http://www.../images/icon_tree1.gif');" ...

Answer 2

You need to pass a string to the onclick handler onclick="openWindow(1, 2, 3, 'http://...')" Some other comments:
1, If your anchor doesn't actually take the user anywhere, consider not to use <a> rather than href="javascript:void();"
2, try not to mix javascript with html. so link your event handler to the DOM element in a <script> tag.
