我有這段代碼。JQuery獲取文本以元素開始

我想要得到的前500個字符與$(".elt")
開始,像這樣:

只是文本,刪除所有的HTML標記。
對不起,我的英文太爛了,還有$('#elt')之前的文本,我只希望文本以$('#elt')開頭。 – user615816 2012-03-21 12:13:28
你能舉幾個比較小的例子,只有20個字符嗎? – callumacrae 2012-03-21 12:14:23
我的意思是,找到元素,並獲得它的文本'text1'。 然後得到這個元素後面的所有文本,'text2',然後'(text1 + text2).slice(0,500);' – user615816 2012-03-21 12:40:09
