jQueryあれこれ

Last updated at Posted at 2018-03-27

何度も調べていて、馬鹿らしいのでまとめた

要素の取得方法

// id
$('#hoge').val()

//class
$('.hoge').val()

// name
$('[name=hoge]').val()

// data属性
$('[data-***=hoge]').val()

ループ


var array = [];
$.each(array, function(index, value)) {
    // ループを抜け出す時(break)
    return false;

    // 処理をスキップする時(continue)
    return true;
};

//targetContent: .Class #id [data-***=hoge] etc...
targetContent.each( function( index, element ) {
    // ループを抜け出す時(break)
    return false;
    
    // 処理をスキップする時(continue)
    return true;
});

イベントバインド


//event : click,change etc...
//targetContent: .Class #id [data-***=hoge] etc...

// 動的に追加された項目のイベントも検知可能
$(document).on('event', 'targetContent', function () {
    // あれこれ
});

// 動的に追加された項目のイベントは「検知不可」
$('targetContent').on('event' , function () {
    // あれこれ
});
