[英]how to get a particular cell value from dynamic table using javascript
[英]how to find cell & get cell value in html Dynamic table use for jquery or javascript?
我有动态表。 我正在尝试使用 jquery“最近和查找”选项来获取单元格值。 但不回应它。
这是 html 代码部分。
<td>
<div id="ctrl-qun-row<?php echo $row; ?>-holder" class="">
<input id="ctrl-qun-row<?php echo $row; ?>" value="<?php echo $this->set_field_value('qun',"", $row); ?>" type="number" placeholder="Enter Qun" step="0.1" required="" name="row<?php echo $row ?>[qun]" class="form-control " />
</div>
</td>
我正在尝试编写使用过的 keyup 事件的脚本。
$('#ctrl-qun').on('keyup', function(){
var rowtoatal =0;
var $row =$(this).closest("td");
var qun2 =parseFloat($row.find('.qun').val());
alert($("#qun2").val()); //remove after testing
});
您需要获取数量发生变化的最接近的tr
,并使用此tr
我们可以获得unit price
的值并将总计添加到sub total
计列。
演示代码(在输入的值属性中添加了虚拟数据):
//on change of qty $('.qtn').on('change keyup ', function() { //getting closest tr var elem = $(this).closest(".input-row"); //get qty value var qty = parseFloat($(this).val()); var rowtoatal = 0; //get unit price value var $row = parseFloat(elem.find("td input.unit").val()); rowtoatal = qty * $row; console.log(qty + " * " + $row + " = " + rowtoatal) //adding total to sub_total elem.find("td input.sub_total").val(rowtoatal) });
