javascript - Laravel Blade : Parse error: syntax error, 意外 ':' ，预期 '('

Question

我正在尝试使用 laravel 在 if 语句中运行 javascript 函数，但在尝试这样做时收到以下错误:

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 部分需要另一个语句(比较某些内容或期望 bool 值)。

如果将 @elseif 更改为 @else，它应该可以工作。

您的新脚本将是这样的:

<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>
