Question

I like the Razor syntax a lot, but it certainly falls short of perfect. For example, I have the following block of markup.

@if (Model.FeaturedDestinations != null && Model.FeaturedDestinations.Count() > 0)
{
    int column = 0;

    foreach (var d in Model.FeaturedDestinations)
    {
        column++;
        if (column > 4)
        {
            </div>
            @{ column = 1; }
        }
        if (column == 1)
        {
            @:<div class="row-fluid">
        }
        <div class="span3">
            @RenderDestination(d)
        </div>
    }
    </div>
}

因此,编辑给我一个粗略的栏目,显示我在开幕前有一个终点站:<代码><div> tag。我可以这样生活。但是,当我管理时,我实际上会遇到以下操作时间错误:

贴上“div”的末端标签,没有相应的开端。您的开端/主角是否适当平衡?

显然,我不能生活在这个时代! 因此,在处理这一案件时是否有任何骗子? 我知道,就我所希望的标志而言,我做了些什么。但是,Razor没有这样做,而是接手。

为什么黑板正在核对平衡标签的周期?

Answer 1

出于我不理解的原因,以下措施纠正了这一问题:

@if (Model.FeaturedDestinations != null && Model.FeaturedDestinations.Count() > 0)
{
    int column = 0;

    foreach (var d in Model.FeaturedDestinations)
    {
        column++;

        if (column > 4)
        {
            @:</div>
            column = 1;
        }

        if (column == 1)
        {
            @:<div class="row-fluid">
        }
        <div class="span3">
            @RenderDestination(d)
        </div>
    }
    @:</div>
}

Note the addition of @: before several tags. 我不知道为什么这些是必要的,即Razor强调,它承认这些是标签,而不是编码。

而且,为什么这造成错误消失? 造成时间错误的东西没有改变。也许有人能够填满我身上的.子。

你们需要添加@:在标签前(如在标的答案中确定的)。这一博客条目解释了以下原因:

博客:

One of the techniques that Razor uses to implicitly identify when a code block ends is to look for tag/element content to denote the beginning of a content region.

以及

Not all content container blocks start with a tag element tag, though, 以及 there are scenarios where the Razor parser can’t implicitly detect a content block.

Razor addresses this by enabling you to explicitly indicate the beginning of a line of content by using the @: character sequence within a code block. The @: sequence indicates that the line of content that follows should be treated as a content block:
