仅显示选择的项目-用JavaScript替换innerHTML

标签: javascript innerhtml

我正在尝试使用下拉按钮进行“过滤条件” 选择。
只要用户单击特定类型的商品(例如我的示例中的衣服),那么html只会显示符合条件的商品(仅衣服)。我可以设法选择所需的项并放入数组中,但是,当我尝试用新数组替换 div 时,输出为[object HTML Element]
有趣问题是如果我console.log使用特定值的数组,(array[0])它显示了我需要的html代码。

<div class="dropdown-menu" >
                <a class="dropdown-item" onClick="filter('clothes')" >Clothes</a>
<a class="dropdown-item" onClick="filter('electronics')" >Electronics</a>
</div>

 <div id="testSearch">
            <section name="product"> 
                <img value="clothes" src="./some.jpg" alt="Clothes 01">
                <h5>Electronic</h5>
            </section>
                <section name="product"> 
                <img value="electronics" src="./some2.jpg" alt="Electronics 01">
                <h5>Electronic</h5>
            </section>

</div>

 <!-- My code has different sections with a variety of value/h5 -->

<script>
function filter(x) {

    var arraySearch = [];

    var input = document.getElementsByName('product');

    for (i=0; i < input.length; i++) {

    if(input[i].innerHTML.indexOf(x) > 0 ) {
        arraySearch[i]= input[i];
        result = result + arraySearch[i];
        }

    }
    document.getElementById('testSearch').innerHTML = result;
    <!-- my html display only [object HTMLElement], if more than a section matches, then it displays the [object HTMLElement] times the number of sections matched -->

}

</script>

我希望[object HTMLElement]的输出是符合条件的部分。

我已经做到了!将数组传递到.outerHTML

时,我几乎需要的是var result.

这是工作代码:

<div class="dropdown-menu" >
                <a class="dropdown-item" onClick="filter('clothes')" >Clothes</a>
                <a class="dropdown-item" onClick="filter('electronics')" >Electronics</a>
</div>

 <div id="testSearch">
            <section name="product"> 
                <img value="clothes" src="./some.jpg" alt="Clothes 01">
                <h5>Electronic</h5>
            </section>
                <section name="product"> 
                <img value="electronics" src="./some2.jpg" alt="Electronics 01">
                <h5>Electronic</h5>
            </section>

</div>

 <!-- My code has different sections with a variety of value/h5 -->

<script>
function filter(x) {

    var arraySearch = [];

    var input = document.getElementsByName('product');
    var result = " ";

    for (i=0; i < input.length; i++) {

    if(input[i].innerHTML.indexOf(x) > 0 ) {
        arraySearch[i]= input[i];
        result = result + arraySearch[i].outerHTML;
        }

    }
    document.getElementById('testSearch').innerHTML = result;

}

</script>

就是这样。希望对别人有帮助。
