在enquire.js注册方法中使用变量

Question

I am trying to using a variable in the register method of enquire.js. I'm going to be reusing enquire in a few different places in my javascript file, so I would like to be able to manage the widths it is using easier.

This is the basic call

enquire.register("screen and (max-width:860px)", {

});

This is sort of what I was hoping I could do but it's not working.

var $small = '600px';

enquire.register("screen and (max-width:'$small')", {

});

Answer 1

Ah. Me being stupid and forgetting how concatenating works. I needed to end the string with the same type of quotes and then use the plus symbol to concatenate the variable. I then used the same quotes again to finish open and close the remainder of the string.

var $small = '600px';

enquire.register("screen and (max-width:" + $small + ")", {

});
