        // BAR CHART
        if (sparklineType == 'bar') {

                barColor = $this.data('sparkline-bar-color') || $this.css('color') || '#0000f0',
                sparklineHeight = $this.data('sparkline-height') || '26px',
                sparklineBarWidth = $this.data('sparkline-barwidth') || 5,
                sparklineBarSpacing = $this.data('sparkline-barspacing') || 2,
                sparklineNegBarColor = $this.data('sparkline-negbar-color') || '#A90329',
                sparklineStackedColor = $this.data('sparkline-barstacked-color') || ["#A90329", "#0099c6", "#98AA56", "#da532c", "#4490B1", "#6E9461", "#990099", "#B4CAD3"];

            $this.sparkline('html', {
                barColor : barColor,
                type : sparklineType,
                height : sparklineHeight,
                barWidth : sparklineBarWidth,
                barSpacing : sparklineBarSpacing,
                stackedBarColor : sparklineStackedColor,
                negBarColor : sparklineNegBarColor,
                zeroAxis : 'false'
            });

        }

对于上面 JSHINT 中的代码，我收到以下错误消息：

“预期一个赋值或函数调用，而是看到一个表达式”

有人可以告诉我如何解决这个问题吗？

谢谢！

这个错误（逗号）

barColor = $this.data('sparkline-bar-color') || $this.css('color') || '#0000f0',
sparklineHeight = $this.data('sparkline-height') || '26px',
sparklineBarWidth = $this.data('sparkline-barwidth') || 5,
sparklineBarSpacing = $this.data('sparkline-barspacing') || 2,
sparklineNegBarColor = $this.data('sparkline-negbar-color') || '#A90329',
sparklineStackedColor = $this.data('sparkline-barstacked-color') || ["#A90329", "#0099c6", "#98AA56", "#da532c", "#4490B1", "#6E9461", "#990099", "#B4CAD3"];

试试这个（分号 - ;）

barColor = $this.data('sparkline-bar-color') || $this.css('color') || '#0000f0';
sparklineHeight = $this.data('sparkline-height') || '26px';
sparklineBarWidth = $this.data('sparkline-barwidth') || 5;
sparklineBarSpacing = $this.data('sparkline-barspacing') || 2;
sparklineNegBarColor = $this.data('sparkline-negbar-color') || '#A90329';
sparklineStackedColor = $this.data('sparkline-barstacked-color') || ["#A90329", "#0099c6", "#98AA56", "#da532c", "#4490B1", "#6E9461", "#990099", "#B4CAD3"];

布尔表达式依赖于 null 或 undefined 的“虚假性”来决定是分配 $this.data 还是数组文字。我的猜测是，jshint 希望您明确分配值，以便您可以明确检查 $this.data 是否为 null 或 undefined，然后进行相应的分配。
