javascript - jQuery 优化 - 干

Question

我的情况很简单:

$("#check-in").dateDropper({
    years_multiple: "10",
    format: "d-m-Y",
    minYear: "2015",
    maxYear: "2016",
    lang: "pt",
    animation: "bounce",
    placeholder: "Dia da entrada."
});

$("#check-out").dateDropper({
    years_multiple: "10",
    format: "d-m-Y",
    minYear: "2015",
    maxYear: "2016",
    lang: "pt",
    animation: "bounce",
    placeholder: "Dia da saída."
});

唯一的区别是占位符:“...”。

如何优化此代码使其不重复(DRY)？

试试这个:

$("#check-in, #check-out").dateDropper({
    years_multiple: "10",
    format: "d-m-Y",
    minYear: "2015",
    maxYear: "2016",
    lang: "pt",
    animation: "bounce",
    placeholder:($(this).attr('id') == "check-in" ? "Dia da entrada." : "Dia da saída.")
});
