示例1: BuildFallbackBlock
private void BuildFallbackBlock(TagHelperAttributeList attributes, DefaultTagHelperContent builder)
{
EnsureGlobbingUrlBuilder();
var fallbackSrcs = GlobbingUrlBuilder.BuildUrlList(FallbackSrc, FallbackSrcInclude, FallbackSrcExclude);
if (fallbackSrcs.Any())
{
// Build the <script> tag that checks the test method and if it fails, renders the extra script.
builder.AppendHtml(Environment.NewLine)
.AppendHtml("<script>(")
.AppendHtml(FallbackTestExpression)
.AppendHtml("||document.write(\"");
// May have no "src" attribute in the dictionary e.g. if Src and SrcInclude were not bound.
if (!attributes.ContainsName(SrcAttributeName))
{
// Need this entry to place each fallback source.
attributes.Add(new TagHelperAttribute(SrcAttributeName, value: null));
}
foreach (var src in fallbackSrcs)
{
// Fallback "src" values come from bound attributes and globbing. Must always be non-null.
Debug.Assert(src != null);
builder.AppendHtml("<script");
foreach (var attribute in attributes)
{
if (!attribute.Name.Equals(SrcAttributeName, StringComparison.OrdinalIgnoreCase))
{
var encodedKey = JavaScriptEncoder.JavaScriptStringEncode(attribute.Name);
var attributeValue = attribute.Value.ToString();
var encodedValue = JavaScriptEncoder.JavaScriptStringEncode(attributeValue);
AppendAttribute(builder, encodedKey, encodedValue, escapeQuotes: true);
}
else
{
// Ignore attribute.Value; use src instead.
var attributeValue = src;
if (AppendVersion == true)
{
attributeValue = _fileVersionProvider.AddFileVersionToPath(attributeValue);
}
// attribute.Key ("src") does not need to be JavaScript-encoded.
var encodedValue = JavaScriptEncoder.JavaScriptStringEncode(attributeValue);
AppendAttribute(builder, attribute.Name, encodedValue, escapeQuotes: true);
}
}
builder.AppendHtml("><\\/script>");
}
builder.AppendHtml("\"));</script>");
}
