测试过，不错。

(function($) {
$.fn.breakWords = function() {
this.each(function() {
if(this.nodeType !== 1) { return; }

if(this.currentStyle && typeof this.currentStyle.wordBreak === 'string') {

this.runtimeStyle.wordBreak = 'break-all';
}
else if(document.createTreeWalker) {

var trim = function(str) {
str = str.replace(/^/s/s*/, '');
var ws = //s/,
i = str.length;
while (ws.test(str.charAt(--i)));
return str.slice(0, i + 1);
};

//For Opera, Safari, and Firefox
var dWalker = document.createTreeWalker(this, NodeFilter.SHOW_TEXT, null, false);
var node,s,c = String.fromCharCode('8203');
while (dWalker.nextNode()) {
node = dWalker.currentNode;
//we need to trim String otherwise Firefox will display
//incorect text-indent with space characters
s = trim( node.nodeValue ).split('').join(c);
node.nodeValue = s;
}
}
});

return this;
};
})(jQuery);
