主要是flex 在绑定里面加两个或者多个判断条件的情况。

比如visible="{ A && B}"表达这样一个意思时,出现标题错误。 主要是xml无法解析 &&这样一个逻辑符号。所以要将他写出

visible="{(A)&&(B)}"这样就可以了。。

If you’ve ever written code in a binding tag and gotten aspecial character error try html-encoding the character like you’ddo if you were encoding regular text:

Error:

<mx :TextInput text= "{(_Feed.url&&!_Feed.isTemporary)?_Feed.url:'Save Feed to generateURL'}" />

Works:

<mx :TextInput text= "{(_Feed.url&amp;&amp;!_Feed.isTemporary)?_Feed.url:'SaveFeed to generate URL'}" />

It makes sense after the fact but before you actually do it,itjust looks odd to html-encode youractionscript.-翻译:运行的时候是能运行的通的,但是,在as代码里面,看上去有点怪怪的。。

大概的意思就是我上面的意思了。

猜你在找的XML相关文章
