javascript - 遍历 HTML 表并过滤某些列值

Question

我使用下面的JS来迭代一个html表，并从表中的许多行中提取第1列和第2列的值，我得到的值包含一堆我不需要的信息，即

我得到第 1 列的以下内容:

<div class="ui-input-text ui-body-inherit ui-corner-all ui-shadow-inset">
    <input name="asset_cost_19" type="text" value="$5,000.00">
</div>

我只想获得美元值(value):

$5,000.00

对于第 2 列，我得到以下信息:

<fieldset data-role="controlgroup" data-type="horizontal" class="ui-controlgroup ui-controlgroup-horizontal ui-corner-all">
    <div class="ui-controlgroup-controls ">
        <div class="ui-checkbox ui-mini">
            <label for="asset_allocation_capex_19" class="ui-btn ui-corner-all ui-btn-inherit ui-checkbox-off ui-first-child">
                Capex
            </label>
            <input type="checkbox" name="asset_allocation_capex_19" id="asset_allocation_capex_19" data-mini="true">
        </div>                                                                                                                              
        <div class="ui-checkbox ui-mini">
            <label for="asset_allocation_opex_19" class="ui-btn ui-corner-all ui-btn-inherit ui-checkbox-on ui-btn-active ui-last-child">
                Opex
            </label>
           <input type="checkbox" name="asset_allocation_opex_19" id="asset_allocation_opex_19" data-mini="true" checked="">
        </div>                                                                                                                          
    </div>
</fieldset> 

我想知道在哪里检查asset_allocation_opex_或asset_allocation_capex_，即

checked=""

以第 11 行为例

<input type="checkbox" name="asset_allocation_opex_11" id="asset_allocation_opex_11" data-mini="true" checked="">    
<input type="checkbox" name="asset_allocation_capex_11" id="asset_allocation_capex_11" data-mini="true">

代码:

$("#myTable_asset").children("tbody").children("tr").each(function (i) {
    var $this = $(this);
    var my_td = $this.children("td");
    var second_col = my_td.eq(1);
    var third_col = my_td.eq(2);
    console.log("Second Column Value (row " + i + "): " + second_col.html());
    console.log("Third Column Value (row " + i + "): " + third_col.html());
});

Answer 1

替换

console.log("Second Column Value (row " + i + "): " + second_col.html());

到

console.log("Second Column Value (row " + i + "): " + second_col.find("input[type=text]").val());
