Jquery UI autoComplete 设置max

好像新版的Jquery UI,autoComplete的options里面没有max，不知道是不是我没有知道，如果数据量很大，有可能显示非常。所以修改了一下代码，定死了，没有添加到options里面去。

在Jquery-ui.js的6659行代码处，_normalize函数里面。

原来是：

[javascript] view plaincopy

1. _normalize:?function(?items?)?{??????????//?assume?all?items?have?the?right?format?when?the?first?item?is?complete??
2. ????????if?(?items.length?&&?items[0].label?&&?items[0].value?)?{??????????????return?items;??
3. ????????}??????????return?$.map(?items,?function(?item?)?{??
4. ????????????if?(?typeof?item?===?"string"?)?{??????????????????return?{??
5. ????????????????????label:?item,??????????????????????value:?item??
6. ????????????????};??????????????}??
7. ????????????return?$.extend({??????????????????label:?item.label?||?item.value,??
8. ????????????????value:?item.value?||?item.label??????????????},?item?);??
9. ????????});??????},??

修改为：

[javascript] view plaincopy

1. _normalize:?function(?items?)?{??????????//?assume?all?items?have?the?right?format?when?the?first?item?is?complete??
2. ????????if?(?items.length?&&?items[0].label?&&?items[0].value?)?{??????????????return?items;??
3. ????????}??????????var?i=0;??
4. ????????return?$.map(?items,?function(?item?)?{??????????????if(i?>=?20?)??
5. ????????????????return;??????????????i++;??
6. ????????????if?(?typeof?item?===?"string"?)?{??????????????????return?{??
7. ????????????????????label:?item,??????????????????????value:?item??
8. ????????????????};??????????????}??
9. ????????????return?$.extend({??????????????????label:?item.label?||?item.value,??
10. ????????????????value:?item.value?||?item.label??????????????},?item?);??
11. ????????});??????},??
