我使用上面的代码....一旦我输入州名....当我们输入另一个州名时，它不应出现在下一次尝试中

Answer 1

我详细阐述了henkieee的评论：

var data = "AndraPradesh;ArunachalPradesh;Assam;Bihar;Chhattisgarh;Goa;Gujarat;Haryana;HimachalPradesh;Jammuan&Kashmir;Jharkhand;Karnataka;Kerala;MadyaPradesh;Maharashtra;Manipur;Meghalaya;Mizoram;Nagala;Orissa;Punjab;Rajasthan;Sikkim;TamilNadu;Tripura;Uttaranchal;UttarPradesh;WestBengal".split(";");

var distinct = [];

$.each(data , function(i, el){
    if($.inArray(el, distinct ) === -1) 
        distinct.push(el);
});

//distinct will not contain any duplicates

或者如果你不想使用jquery（不会在ie7中工作）：

var distinct = data.filter(function(elem, pos) {
    return data.indexOf(elem) == pos;
});
