Why I can't use variable into attribute? about vash HOT 5 CLOSED

This is code also doesn't work https://gist.github.com/gr1feel/5418016
I suppose what problem in parentheses.

from vash.

I'm not sure I follow, those render just fine for me:

$ echo '<a onclick="alert('@model.text1')">click me!</a> ' | ./node_modules/vash/bin/vash --json '{"debug": false}' --render '{ "text1": "hello" }'
<a onclick="alert(hello)">click me!</a>

drewp@SpottedRadioFreeAir /tmp/vash-test$ node
> var vash = require('vash');
undefined
> var tpl = vash.compile("<a onclick=\"alert('@model.text1')\">click me!</a>")
undefined
> tpl({ text1: "hello" })
'<a onclick="alert(\'hello\')">click me!</a>'

Could you provide more details as to what "fail" means in your case?

from vash.

Any other details you can provide?

from vash.

Hi,
Sorry for delay. Check this example (pages /test1 and /test2).

https://docs.google.com/file/d/0B0E2riyj_WiwVDBNMnpvTndBaFU/view

from vash.

Ok, thanks for the examples, they really help.

The issue is that a <br /> tells Vash to enter and immediately exit markup mode and return to the previous mode, which is this case is a code block. Thus Text1: and Text2: are being interpreted as code instead of markup. Vash requires that any actual content be wrapped in either html tags (or the fake <text> tag) or an @: for a single line.

There is another issue too in the same vein. The parentheses in (@model.text2) are being interpreted as code. When compiled, it looks like this:

(__vbuffer.push(html.escape(model.text2).toHtmlString());)

A semicolon is not valid JS within the grouping parentheses, so this is actually not even compiling. The error reporting is giving you a false sense of where the error is happening because it's not actually at runtime, but rather at compile time. This is just bad reporting that I've been meaning to fix, and have opened an issue to keep track of it (#22).

Your immediate solution:

@html.block('content', function(model){

  @* Remember that <text> tags are not rendered! *@
  <text>
  <br/>Text1: @model.text1
  <br/>Text2: @model.text2

  <br/>@model.child.xxx


  <span>hi</span> (@model.text2)
  </text>
})

There are others, like using @: on each line (pretty gross, just an example):

@html.block('content', function(model){

  @:<br/>Text1: @model.text1
  @:<br/>Text2: @model.text2

  <br/>@model.child.xxx


  @:<span>hi</span> (@model.text2)
})

from vash.
