Javascript（object.innerhtml）與IE不兼容

Question

我創建了一個腳本，該腳本可以根據所選類別更改組合框。 問題是該腳本可用於Internet Explorer（版本7+）以外的所有其他瀏覽器。 我沒有收到錯誤消息，表明IE不喜歡object.innerhtml。 我該怎么解決？

工作示例： http : //adcabinetsales.com/style-chooser.html

function ChangeCabinetCollection() {
    if (document.getElementById("cabinet_collection").value == "broughton") {
        // COPY VALUES
        var first = document.getElementById('broughton_styles');
        var options = first.innerHTML;
        var second = document.getElementById('cabinet_selector');

        // REPLACE VALUES
        second.innerHTML = options;

        // CHANGE CABINET IMAGE TO BE IN THE COLLECTION OF CHOICE
        changeDoor("cabinet_selector");
    } else if (document.getElementById("cabinet_collection").value == "specialty") {
        // COPY VALUES
        var first = document.getElementById('cabinet_style');
        var options = first.innerHTML;
        var second = document.getElementById('cabinet_selector');

        // REPLACE VALUES
        second.innerHTML = options;

        // CHANGE CABINET IMAGE TO BE IN THE COLLECTION OF CHOICE
        changeDoor("cabinet_selector");
    }
}

function ChangeGraniteCollection() {
    if (document.getElementById("granite_collection").value == "new_arrivals") {
        // COPY VALUES
        var first = document.getElementById('granite_new');
        var options = first.innerHTML;
        var second = document.getElementById('granite_selector');

        // REPLACE VALUES
        second.innerHTML = options;

        // CHANGE CABINET IMAGE TO BE IN THE COLLECTION OF CHOICE
        changeGranite("granite_selector");
    } else if (document.getElementById("granite_collection").value == "Specialty Styles") {
        // COPY VALUES
        var first = document.getElementById('specialty_granite_styles');
        var options = first.innerHTML;
        var second = document.getElementById('granite_selector');

        // REPLACE VALUES
        second.innerHTML = options;

        // CHANGE CABINET IMAGE TO BE IN THE COLLECTION OF CHOICE
        changeGranite("granite_selector");
    }
}

Answer 1

通常不是.innerHTML ；它不是.innerHTML 。 它與<select>元素一起使用會導致問題。 有兩種方法可以解決此問題。 一種簡單的方法是替換整個<select>元素以及選項列表。 也就是說，如果您的HTML如下所示：

<select name=whatever id=whatever>
  <option value=1>Hello
  <option value=2>World
</select>

然后，您可以將其更改為：

<span class=select-wrapper>
  <select name=whatever id=whatever>
    <option value=1>Hello
    <option value=2>World
  </select>
</span>

然后只需將<span>包裝器的.innerHTML替換為<select> 。

解決該問題的另一種方法是建立一個Option實例數組，並更新<select>元素的“ options”屬性。

我不確定為什么您會遇到IE7 +的問題，我沒有要測試的Microsoft產品，但是可能存在以下錯誤：

BUG：Internet Explorer無法設置選擇對象的innerHTML屬性

但是，使用@Pointy答案，則可以使用Node.cloneNode Node.replaceChild像這樣執行select的替換，而不是包裝元素。 我相信這是跨瀏覽器。

的HTML

<select name="granite_collection" id="granite_collection">
    <option selected="selected">Choose a Collection</option>
    <option value="new_arrivals">Granite: New Arrivals</option>
    <option value="Specialty Styles">Granite: Specialty Styles</option>
</select>
<select name="granite_selector" id="granite_selector"></select>
<select name="cabinet_style" id="cabinet_style" style="visibility:hidden;">
    <option value="images/doorstyles/Brandy wine.jpg">Brandy Wine</option>
    <option value="images/doorstyles/Canvas.jpg">Canvas</option>
    <option value="images/doorstyles/Country Linen.jpg">Country Linen</option>
    <option value="images/doorstyles/Expresso.jpg">Expresso</option>
    <option value="images/doorstyles/Mocha glazed.jpg">Mocha Glazed</option>

    <option value="images/doorstyles/Dillon1.jpg">Dillon1</option>
    <option value="images/doorstyles/Dillon2.jpg">Dillon2</option>
</select>

Java腳本

var graniteCollection = document.getElementById("granite_collection"),
    graniteSelector = document.getElementById("granite_selector"),
    cabinetStyle = document.getElementById("cabinet_style");

graniteCollection.onchange = function () {
    var clone = cabinetStyle.cloneNode(true);

    clone.id = graniteSelector.id;
    clone.name = graniteSelector.name;
    clone.style.visibility = "";
    graniteSelector.parentNode.replaceChild(clone, graniteSelector);
}
