Autocomplete jquery自动完成如何恢复模糊值?

Autocomplete jquery自动完成如何恢复模糊值?,autocomplete,restore,blur,Autocomplete,Restore,Blur,我试过这个: $(function(){ $('.aComplete').each(function(){ var inputField = $(this); $(this).autocomplete({ source :"index.php?action=acomplete&name="+$(this).attr("name"), minLength:1 })

我试过这个:

$(function(){
    $('.aComplete').each(function(){

        var inputField = $(this);

        $(this).autocomplete({
            source   :"index.php?action=acomplete&name="+$(this).attr("name"),
            minLength:1
        })

        //clear the input on click
        .focus(function(){
            if(inputField.val(undefined) != true){
                temp = inputField.val();
                inputField.val(undefined);
        }
        inputField.data("autocomplete").search(inputField.val());

        //restore initial value if nothing was typed
        }).blur(function(){
            //check if field is empty and restore value from `temp` if so
            alert(temp); //this shows empty string
        });
    });
});
但是,有趣的是,当我在blur事件中调用变量
temp
时,它变成了一个空字符串


为什么会发生这种情况?如何修复?

发现了故障,尽管我无法完全解释自己…
我刚刚移动了
temp=inputField.val()如果(inputField.val(未定义)!=true){
成功了
