Question

我要在按钮上附加一个选择框，然后单击“从查询中获取选择框值”，但是一个文件的名称不能显示控制台中的错误。附加代码为

$(document).ready(function () {
$("#btnAdd").click(function() { 
$(".zims").append('<tr> <td><select name="material_id[]" required class="s_box"><option value="">-Select Material-</option><?php foreach ($get_mat as $row) {  ?><option value="<?php echo $row->id ?>"><?php echo $row->name ?></option> <?php } ?>  </select> </td></tr>');
}); });

$ row->名称有问题！用有效的ID替换名称时

查询是

$this->db->select('*');
$this->db->from('material');
$query = $this->db->get();
return $query->result();

为什么这说明了如何解决该问题？名称在该循环中，加号按钮不起作用，但替换为ID则起作用！

$ get_mat 结果是

array(33) { [0]=> object(stdClass)#97 (2) { ["id"]=> string(1) "1" ["name"]=> string(5) " Nail" } [1]=> object(stdClass)#98 (2) { ["id"]=> string(1) "2" ["name"]=> string(6) "Washer" } [2]=> object(stdClass)#99 (2) { ["id"]=> string(1) "3" ["name"]=> string(5) "L bow" } [3]=> object(stdClass)#100 (2) { ["id"]=> string(1) "4" ["name"]=> string(9) "Chemical " } [4]=> object(stdClass)#101 (2) { ["id"]=> string(1) "5" ["name"]=> string(19) "Polishing material " } [5]=> object(stdClass)#102 (2) { ["id"]=> string(1) "6" ["name"]=> string(6) "Paints" } [6]=> object(stdClass)#103 (2) { ["id"]=> string(1) "7" ["name"]=> string(3) "Bit" } [7]=> object(stdClass)#104 (2) { ["id"]=> string(1) "8" ["name"]=> string(6) "Cement" } [8]=> object(stdClass)#105 (2) { ["id"]=> string(1) "9" ["name"]=> string(7) "M Sand " } [9]=> object(stdClass)#106 (2) { ["id"]=> string(2) "10" ["name"]=> string(7) "P Sand " } [10]=> object(stdClass)#107 (2) { ["id"]=> string(2) "11" ["name"]=> string(11) "20 mm metal" } [11]=> object(stdClass)#108 (2) { ["id"]=> string(2) "12" ["name"]=> string(5) "Chips" } [12]=> object(stdClass)#109 (2) { ["id"]=> string(2) "13" ["name"]=> string(7) "Q dust " } [13]=> object(stdClass)#110 (2) { ["id"]=> string(2) "14" ["name"]=> string(13) "Baniyan waste" } [14]=> object(stdClass)#111 (2) { ["id"]=> string(2) "15" ["name"]=> string(13) "Cutting blade" } [15]=> object(stdClass)#112 (2) { ["id"]=> string(2) "16" ["name"]=> string(15) "Electrical item" } [16]=> object(stdClass)#113 (2) { ["id"]=> string(2) "17" ["name"]=> string(14) "Plumbing item " } [17]=> object(stdClass)#114 (2) { ["id"]=> string(2) "18" ["name"]=> string(15) "Carpentry item " } [18]=> object(stdClass)#115 (2) { ["id"]=> string(2) "19" ["name"]=> string(14) "Painting item " } [19]=> object(stdClass)#116 (2) { ["id"]=> string(2) "20" ["name"]=> string(4) "Rope" } [20]=> object(stdClass)#117 (2) { ["id"]=> string(2) "22" ["name"]=> string(11) "Level hose " } [21]=> object(stdClass)#118 (2) { ["id"]=> string(2) "23" ["name"]=> string(7) "Fissure" } [22]=> object(stdClass)#119 (2) { ["id"]=> string(2) "24" ["name"]=> string(11) "40 mm metal" } [23]=> object(stdClass)#120 (2) { ["id"]=> string(2) "25" ["name"]=> string(13) "Hardware Item" } [24]=> object(stdClass)#121 (2) { ["id"]=> string(2) "26" ["name"]=> string(6) "Bricks" } [25]=> object(stdClass)#122 (2) { ["id"]=> string(2) "27" ["name"]=> string(6) "Rubble" } [26]=> object(stdClass)#123 (2) { ["id"]=> string(2) "28" ["name"]=> string(6) "Steel " } [27]=> object(stdClass)#124 (2) { ["id"]=> string(2) "29" ["name"]=> string(14) "Polishing item" } [28]=> object(stdClass)#125 (2) { ["id"]=> string(2) "30" ["name"]=> string(11) "silicon gun" } [29]=> object(stdClass)#126 (2) { ["id"]=> string(2) "31" ["name"]=> string(13) "Granite Blade" } [30]=> object(stdClass)#127 (2) { ["id"]=> string(2) "32" ["name"]=> string(5) "Blade" } [31]=> object(stdClass)#128 (2) { ["id"]=> string(2) "33" ["name"]=> string(5) "Water" } [32]=> object(stdClass)#129 (2) { ["id"]=> string(2) "34" ["name"]=> string(11) "Glass Point" } }

请更改此类附加代码

$(document).ready(function () {
$("#btnAdd").click(function() { 
$(".zims").append('<tr> <td><select name="material_id[]" required class="s_box"><option value="">-Select Material-</option><?php foreach ($get_mat as $row) {  ?><option value="<?php echo $row->id ?>"><?php echo trim($row->name) ?></option> <?php } ?>  </select> </td></tr>');
}); });

此名称有一些空格，请使用修剪删除空格
