如何在Bootstrap抓取中更改z-index？

Question

我使用bootstrap咆哮发出以下呼叫：

props = props || {};
props.params = props.params || {};
props.type = props.type || 'info';
props.align = props.align || 'center';
props.offsetAmount = props.offsetAmount || 250;
props.offsetFrom = props.offsetFrom || 'top';
props.width = props.width || 'auto';
props.delay = props.delay || '50000000';
props.allow_dismiss = props.allow_dismiss || true;
props.stackup_spacing = props.stackup_spacing || 10;
props.z_index = props.z_index || 100000;

$.bootstrapGrowl(msg, {
    type: props.type, // (null, 'info', 'danger', 'success', 'warning')
    offset: {
        from: props.offsetFrom,
        amount: props.offsetAmount
    },
    align: props.align,
    width: props.width,
    delay: props.delay,
    allow_dismiss: props.allow_dismiss,
    stackup_spacing: props.stackup_spacing,
    z_index: props.z_index
});

无论我将props.z_index设置为什么，当它出现在页面上时始终显示为9999。其他属性（例如延迟）会有所变化，是否有必要更改z-index？我需要增加价值，但不想在全球范围内仅在特定页面中做到这一点。

它始终使用以下内联样式进行构建：

position: fixed; margin: 0px 0px 0px -44.5px; z-index: 9999; top: 250px; left: 50%;
