冒号和等号的问题 ( 积分: 100 )

javascript中：
var Prototype = {
Version: '1.5.0',
BrowserFeatures: {
XPath: !!document.evaluate
},
ScriptFragment: '(?:<script.*?>)((/n|/r|.)*?)(?:<//script>)',
emptyFunction: function() {},
K: function(x) { return x }
}
和
var Prototype = {
Version＝'1.5.0',
BrowserFeatures＝{
XPath＝ !!document.evaluate
},
ScriptFragment＝'(?:<script.*?>)((/n|/r|.)*?)(?:<//script>)',
emptyFunction＝function() {},
K＝ function(x) { return x }
}
有什么区别呢？

难道等于号的你也行? 你可测试成功过?
