Laravel :解析错误:语法错误，意外':'，期待‘()

Question

我试图使用laravel在if statemenet中运行javascript函数，但在尝试运行javascript函数时会收到以下错误：

Parse error: syntax error, unexpected ':', expecting '(' (View: C:\rcms_w\resources\views\frontend\home.blade.php)

代码：

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

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

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部分需要另一条语句(比较某个东西或期望一个布尔值)。

如果您将@elseif更改为@else，它应该可以工作。

您的新脚本如下：

<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>
