javascript - java脚本中的变量无效或意外标记

问题描述

我在按钮上附加一个选择框单击选择框值是从查询中获取的，但是一个文件没有采用在控制台中显示错误的名称无效或意外的标记附加代码是一个变量

$(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->name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();

为什么这表明如何解决这个问题呢？名称在该循环中，加号按钮不起作用，但替换为 id 工作！

$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" } }

解决方案

请像这样更改附加代码

$(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>');
}); });

此名称有一些空格使用修剪删除空间
