搜索框as3工作不正常

Question

即时通讯有一个问题，我把任何文本或甚至空白空间我仍然在框架170，因为你看到我把171框架在那里，如果我键入“因此”它在171，似乎就像它的工作正常，它只是即使我把错误的文本去帧170，我不能找到问题寿，我也不知道我是否应该做一个else语句，所以如果单词不在列表中它会去其他框架，感谢队友

var i:int = 0; 
var names:Array = new Array("therefore","disciples","nations","baptizing","father","son","holy spirit"); 
var frames:Array = new Array("171","170","170","170","170","170","170","170"); 

button_140.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_4); 

function fl_MouseClickHandler_4(event:MouseEvent):void 
{ 
var searchtext:String = searchtext.text.toLowerCase(); 
findInArray(searchtext); 
gotoAndStop(frames[i]); 
} 

function findInArray(str:String):int 
{ 
for(i=0; i < names.length; i++) 
{ 

     if(names[i] == str) 
     { 
    return i; 
} 
} 
return 0; 
}

为什么你总是去框170：

让我们看看你的函数fl_MouseClickHandler_4：

findInArray(searchtext);//string won't be found so "i" would be 7 (the last index in array) 
gotoAndStop(frames[i]);//so it goes to frame 170 

为您的代码修复：
功能fl_MouseClickHandler_4：

function fl_MouseClickHandler_4(event:MouseEvent):void 
{ 
var searchtext:String = searchtext.text.toLowerCase(); 
var index:int=findInArray(searchtext); 

if(index==-1){ 
    //do something when frame not found 
} 
else{ 
    gotoAndStop(frames[index]); 
} 

功能findInArray：

function findInArray(str:String):int 
{ 
for(i=0; i < names.length; i++) 
{ 

    if(names[i] == str) 
    { 
return i;//return the found index 
} 
} 
return -1;//return -1 if nothing found 
} 

我希望这有助于...

编辑：

您不需要创建一个函数来查找数组中的值。您可以使用Array类内置方法indexOf()查找数组中项目的索引：有关更多信息，请参阅AS3 manual。

theArray.indexOf(theValue); 

返回该值的索引。如果值不在数组中，则返回-1。

试验下面这个例子：

//# declare variables outside of function (make once & re-use) 
var searchtext:String = ""; 
var index:int = 0; 

//# after updating searchtext string with user-text then run function below 

function fl_MouseClickHandler_4(event:MouseEvent):void 
{ 
    searchtext = searchtext.text.toLowerCase(); 
    index = names.indexOf(searchtext); //test with "holy spirit" 

    if(index == -1) 
    { 
     trace("index is : -1 : No match found"); 
     //do something when frame not found 
    } 
    else 
    { 
     trace("index is : " + index + " ::: result is : " + (frames[index])); 
     gotoAndStop(frames[index]); 
    } 
}
