Escape String - Output rails string in Javascript
提问by cclerv
I'm trying to assign a string value to a javascript object in my .erb file like so:
我正在尝试将字符串值分配给 .erb 文件中的 javascript 对象，如下所示：
var data = {
'name': '<%= @product.name %>',
...
};
The problem is, if the value of nameis Tom's small ears,
问题是，如果值name是Tom's small ears，
the output of data.namewould be Tom's small ears.
的输出data.name将是Tom's small ears。
Is there a way to escape special characters?
有没有办法转义特殊字符？
I tried doing 'name': '<%= raw @product.name %>'but Uncaught SyntaxError: Unexpected identifiergets output into the console.
我尝试这样做，'name': '<%= raw @product.name %>'但Uncaught SyntaxError: Unexpected identifier输出到控制台。
Doing <%= escape_javascript @product.name %>outputs Tom\'s small ears
做<%= escape_javascript @product.name %>输出Tom\'s small ears

You can use escape_javascript()to accomplish that:
你可以用它escape_javascript()来完成：
var data = {
'name': "<%== escape_javascript @product.name %>",
#...
};

The alias of this method is j:
该方法的别名是j：
var data = {
'name': "<%== j @product.name %>"
}
