Question

我正在尝试使用laravel在if statemenet中运行javascript函数但是在尝试执行此操作时收到以下错误：

BlogViewHolder(View itemView) {
            super(itemView);
            mView = itemView;
            textView_title = (TextView) itemView.findViewById(R.id.title);
            textView_decription = (TextView) itemView.findViewById(R.id.description);
            textView_address =(TextView) itemView.findViewById(R.id.address);
            textView_phone =(TextView) itemView.findViewById(phone);
            textView_Pickup =(TextView) itemView.findViewById(pickup);
            textView_Confirm =(TextView) itemView.findViewById(confirm);
            bconfirm = (Button) itemView.findViewById(R.id.bcomfirm);
            bpickup = (Button) itemView.findViewById(R.id.bpickup);

            bpickup.setOnClickListener(this);
            bconfirm.setOnClickListener(this);
}


        @Override
        public void onClick(View v) {

            if (v.getId() == bpickup.getId()) {
                // set your actions
            }
             //here you can use else, if the first one didn't get call 
             //then the second one will be
            if(v.getId() == bconfirm.getId()){
                // set your actions
            }
        }

代码：

您使用此结构：

@if (Auth::user()->roleplay->health_points >= 100) 
    setHealth(1);
@elseif
    setHealth(0.{{ Auth::user()->roleplay->health_points }});
@endif

被解析为

<?php if (Auth::user()->roleplay->health_points >= 100) : ?>
    setHealth(1);
<?php elseif: ?>
    setHealth(0.{{ Auth::user()->roleplay->health_points }});
<?php endif; ?>

elseif部分需要另一个语句（比较某些东西或期望一个布尔值）。

如果您将@elseif更改为@else，则应该有效。

您的新脚本将是：

<script type="text/javascript">
    @if (Auth::user()->roleplay->health_points >= 100) 
        setHealth(1);
    @else
        setHealth(0.{{ Auth::user()->roleplay->health_points }});
    @endif

    @if (Auth::user()->roleplay->energy_points >= 100) 
        setEnergy(1, {{ Auth::user()->roleplay->energy_points }});
    @else
        setEnergy(0.{{ Auth::user()->roleplay->energy_points }}, {{ Auth::user()->roleplay->energy_points }});
    @endif

    @if (Auth::user()->roleplay->hygiene_points >= 100) 
        setHygiene(1, {{ Auth::user()->roleplay->hygiene_points }});
    @else
        setHygiene(0.{{ Auth::user()->roleplay->hygiene_points }}, {{ Auth::user()->roleplay->hygiene_points }});
    @endif

    @if (Auth::user()->roleplay->hunger_points >= 100) 
        setHunger(1, {{ Auth::user()->roleplay->hunger_points }});
    @else
        setHunger(0.{{ Auth::user()->roleplay->hunger_points }}, {{ Auth::user()->roleplay->hunger_points }});
    @endif
</script>
