kissy 中的eval实现一则
没必要废话.一看就明白.
[javascript]
globalEval: function(data) {
if (data && REG_NOT_WHITE.test(data)) {
// Inspired by code by Andrea Giammarchi
// http://webreflection.blogspot.com/2007/08/global-scope-evaluation-and-dom.html
var head = doc.getElementsByTagName('head')[0] || doc.documentElement,
script = doc.createElement('script');
// It works! All browsers support!
script.text = data;
// Use insertBefore instead of appendChild to circumvent an IE6 bug.
// This arises when a base node is used.
head.insertBefore(script, head.firstChild);
head.removeChild(script);
}
}
[/javascript]
