如果選擇了選項A顯示Div X，如果選擇的所有其他選項顯示Div Y使用Jquery

我不知道這是否可能，因爲我從來不需要這樣做，但我需要顯示或隱藏美國數字輸入字段或國際號碼輸入字段，基於是否選擇國家。我不想特別要求每個val =「」，因爲這似乎是一種不好的方式，而是使用其他方式來選擇除value =「US」之外的其他值，例如如果選擇了選項A顯示Div X，如果選擇的所有其他選項顯示Div Y使用Jquery

如果val =「US」顯示，美國數場否則隱藏

如果val =「一切」秀國際號碼別的領域隱藏

我創建了一個工作小提琴澄清我的意思。任何幫助將不勝感激。我似乎無法找到一個解決這個問題

反轉升ogic，使用'！='（不等於）https://jsfiddle.net/k5c0xha0/4/ –

或者更好，把所有內容放在同一個處理程序中：https：//jsfiddle.net/k5c0xha0/5/（當然，是更好的方式來編碼：https：//jsfiddle.net/k5c0xha0/7/ –

謝謝我感謝幫助 – Garrett

您可以在單一change事件函數處理這種情況

$(document).ready(function(){ 
// jquery multiple selector. Dont need to seperately write hide for us-number & int-number 
$('#us-number, #int-number').hide(); 
$('#country').change(function() { 
    if ($('#country').val() == "USA") { 
    $('#int-number').hide(); // hide international num field 
     $('#us-number').show(); //show us num field 
    } else { 
    $('#int-number').show(); // show international num field 
     $('#us-number').hide(); // hide us num field 
    } 
}); 
});

Working Example

編輯

正如Koen所指出的，用戶仍然可以從下拉列表中選擇Country選項。在這種情況下，所有的輸入都會發生。因此，增加了一個else-if循環，以檢查是否值那麼空字符串隱藏兩個輸入欄

$(document).ready(function(){ 
$('#us-number, #int-number').hide(); 
$('#country').change(function() { 

    if ($('#country').val() == "USA") { 
    $('#int-number').hide(); 
     $('#us-number').show(); 
    } else if($('#country').val() == ""){ // Added this else if 
     $('#us-number, #int-number').hide(); 
    } 
    else { 
    $('#int-number').show(); 
     $('#us-number').hide(); 
    } 
}); 
});

不要忘記，用戶可以選擇「國家」選項後，第一次改變，並在你的例子中，它仍然會顯示整數輸入。 – Koen

@Koen謝謝。我已經編輯了答案 – brk

我寫了一個小型圖書館爲此，前一段時間，稱爲Visiblary：

/* 
* params: 
*  - selector: jQuery selector 
*  - init: function which gets the Visiblary object to initialize it 
*  - events: object/array 
*   - root: a selector which contain all the affected tags, default is "body" 
*   - types: array, which contains the string representation of the events 
*   - selector: inner selector to identify the target set 
*   - handler: handler function 
*/ 
function Visiblary(params) { 
    var instance = this; 
    if (!params.toggleClass) { 
     params.toggleClass = "invisible"; 
    } 
    this.hideAll = function() { 
     $(params.selector).addClass(params.toggleClass); 
     return instance; 
    }; 
    this.hideSubset = function(subsetSelector) { 
     $(params.selector).filter(subsetSelector).addClass(params.toggleClass); 
     return instance; 
    }; 
    this.hideOnly = function(subsetSelector) { 
     $(params.selector).not(subsetSelector).removeClass(params.toggleClass); 
     $(params.selector).filter(subsetSelector).addClass(params.toggleClass); 
     return instance; 
    }; 
    this.showAll = function() { 
     $(params.selector).removeClass(params.toggleClass); 
     return instance; 
    }; 
    this.showSubset = function(subsetSelector) { 
     $(params.selector).filter(subsetSelector).removeClass(params.toggleClass); 
     return instance; 
    }; 
    this.showOnly = function(subsetSelector) { 
     $(params.selector).not(subsetSelector).addClass(params.toggleClass); 
     $(params.selector).filter(subsetSelector).removeClass(params.toggleClass); 
     return instance; 
    }; 
    this.invert = function() { 
     $(params.selector).each(function() { 
      $(this).hasClass(params.toggleClass) ? $(this).removeClass(params.toggleClass) : $(this).addClass(params.toggleClass); 
     }); 
     return instance; 
    }; 
    if (!!params.init) { 
     params.init(this); 
    } 
    if (!!params.events) { 
     for (var event in params.events) { 
      $(!!params.events[event].root ? params.events[event].root : "body").on(params.events[event].types.join(" "), params.events[event].selector, params.events[event].handler); 
     } 
    } 
    return instance; 
}

實施例：

var actionButtonVisiblary = new Visiblary({ 
    selector: ".admin-page", 
    events: [ 
     { 
      root: "#admin-action-button-container > .button-action", 
      types: ["click"], 
      handler: function(e) { 
       actionButtonVisiblary.showOnly($(this).data("what")); 
      } 
     } 
    ] 
});

如果選擇了選項A顯示Div X，如果選擇的所有其他選項顯示Div Y使用Jquery
