Question

如何使用循环在javascript数组对象中用单个键插入多个值。我正在创建事件日历以将事件添加到日历。我的代码是

var aColor:uint;
var aRadius:int;
var aShape:Shape;

// Subscribe for MOUSE_DOWN event.
stage.addEventListener(MouseEvent.MOUSE_DOWN, onDown);

function onDown(e:MouseEvent):void
{
    // Set up the new color.
    changeColor();

    // Set up the new circle and assign its reference to the variable.
    // The previous shape, if any, doesn't get destroyed,
    // just no longer accessible via the same variable.
    aShape = new Shape;
    aShape.x = stage.stageWidth / 2;
    aShape.y = stage.stageHeight / 2;
    aShape.graphics.lineStyle(0, 0x000000);

    // Put it UNDER all the other circles.
    addChildAt(aShape, 0);

    // Turn ENTER_FRAME handler on.
    addEventListener(Event.ENTER_FRAME, onFrame);

    // Prepare to intercept the MOUSE_UP event.
    stage.addEventListener(MouseEvent.MOUSE_UP, onUp);
}

function onFrame(e:Event):void
{
    // Increase the radius.
    aRadius++;

    // Draw the circle inside the last added shape.
    aShape.graphics.clear();
    aShape.graphics.beginFill(aColor);
    aShape.graphics.drawCircle(0, 0, aRadius);
    aShape.graphics.endFill();
}

function onUp(e:MouseEvent):void
{
    // Turn ENTER_FRAME handler OFF.
    removeEventListener(Event.ENTER_FRAME, onFrame);

    // Stop intercepting the MOUSE_UP event.
    stage.removeEventListener(MouseEvent.MOUSE_UP, onUp);
}

function changeColor():void
{
    aColor = 0x1000000 * Math.random();
}

使用此代码，我得到了类似的东西，

<script type="text/javascript">
        var a=<?php echo(json_encode($da)); ?>;
        var ev=  <?php echo(json_encode($eve)); ?>;
        var codropsEvents ={};
        for(var i=0;i<a.length;i++)
        {

            codropsEvents[a[i]] = '<span>'+[ev[i]]+'</span>';

        }

        </script>

但是我的日历插件不支持在同一天的多个事件。它仅支持以下内容

var codropsEvents={[date1]:[event1],[date1]:[event2]}

请任何人都可以帮助我注意：$ da是日期数组，$ ev是每个日期中的事件

您可以在数组上使用.push方法。 https://www.w3schools.com/jsref/jsref_push.asp

例如：

如果您有类似您的对象：

var codropsEvents = {[date1]: [], [date2]: []}

您想在这些日期中添加事件

codropsEvents[date1].push("event1")

这会将event1推到date1，因此请在循环中执行以下操作：

 for (var i=0; i<a.length; i++){
     codropsEvents[a[i]].push(ev[i]);
 }

如何在JavaScript中存储多个值和单个键？
