CoffeeScript function argument
提问by pertrai1
I have a function that I want to pass an argument, market, to the function freeSample, but I can't seem to get it set as an argument. Please take a moment to look at my code and help me to understand how to get the market as an argument in the freeSample function.
我有一个函数，我想将参数市场传递给函数 freeSample，但我似乎无法将其设置为参数。请花点时间看看我的代码，帮助我理解如何在 freeSample 函数中将市场作为参数。
(freeSample) ->
market = $('#market')
jQuery('#dialog-add').dialog =
resizable: false
height: 175
modal: true
buttons: ->
'This is Correct': ->
jQuery(@).dialog 'close'
'Wrong Market': ->
market.focus()
market.addClass 'color'
jQuery(@).dialog 'close'
UPDATE: Here is the JavaScript I currently have that I am trying to convert to CoffeeScript.
更新：这是我目前正在尝试转换为 CoffeeScript 的 JavaScript。
function freeSample(market)
{
var market = $('#market');
jQuery("#dialog-add").dialog({
resizable: false,
height:175,
modal: true,
buttons: {
'This is Correct': function() {
jQuery(this).dialog('close');
},
'Wrong Market': function() {
market.focus();
market.addClass('color');
jQuery(this).dialog('close');
}
}
});
}

What you have here is not a function named freeSample. Is an anonymous function with a single argument called freeSample. The syntax for functions in CoffeeScript is like this:
您在这里拥有的不是名为freeSample. 是一个带有单个参数的匿名函数，称为freeSample. CoffeeScript 中函数的语法是这样的：
myFunctionName = (myArgument, myOtherArgument) ->
So in your case it could be something like this:
所以在你的情况下，它可能是这样的：
freeSample = (market) ->
#Whatever
EDIT(after OP updated the question): In your specific case you could do it like so:
编辑（在 OP 更新问题后）：在您的特定情况下，您可以这样做：
freeSample = (market) ->
market = $("#market")
jQuery("#dialog-add").dialog
resizable: false
height: 175
modal: true
buttons:
"This is Correct": ->
jQuery(this).dialog "close"
"Wrong Market": ->
market.focus()
market.addClass "color"
jQuery(this).dialog "close"
PS. There is an (awesome) online tool for converting between js/coffeescript and can be found here: http://js2coffee.org/
