Javascript error in IE8: Not implemented
问题 This one really puzzles me, as the code looks completely harmless. IE8 halts script execution with a message: Not implemented. map.js line:66 char:5 Here is a snip from the code: 63 if(data.map[x] !== undefined && data.map[x][y] !== undefined) { 64 65 left = (x - data.dim.x_min)*32 + 30; 66 top = (data.dim.y_max - y)*32 + 30; 67 68 /* do stuff */ XX } debug info: x:263 data.dim.x_min:263 y:172 data.dim.y_max:174 Data is object returned from JQuery Ajax call. This works in Firefox 3.0 and 3.5,
