我正在尝试使用promises和angularJS.
我的后端正在返回正确的值,但是我的html视图没有显示我的表,其中包含从后端返回的数据.
这有什么不对？
这是我的HTML:
<div ng-app="clinang" ng-controller="pacientesCtrl">
<a class='btn btnprimary' href='/getdadospac/?oper=S' >Button</a>
<table ng-table="tableParams" class="table" show-filter="true">
<tr ng-repeat="paciente in $data">
<td title="'Pront'" filter="{ name: 'text'}" sortable="'pront'">
{{paciente.pront}}</td>
<td title="'Nome'" filter="{ age: 'number'}" sortable="'nome'">
{{paciente.nome}}</td>
</tr>
</table>
</div>
这是我从后端返回的JSON数据:

我希望 um regex 将此字符串转换为有效的 MySQL 十进制数。
可能的值：
"R$ 23.000,20", "23.000,30", "R$ 1300,20", "R$ 100","161,43256"
结果将是：
"23000.20", "23000.30", "1300.20", "100","161.43256"
我的尝试如下，但它不起作用。我只想接受数字和点（。）作为结果。
const str = "R$ 2.200,000";
const res = str
.replace(/R$/gi, "")
.replace(/./gi, "")
.replace(/,/gi, ".");
console.log(res);

at …我有一个猫鼬模式，我只是在原始模式中添加了字段“imagens”。
添加的字段是：
imagens:[{title:{type: String},savedAs:{type: String},file:{type: String}, thumb:{type: String}}],
现在，当我尝试填充“图像”字段并更新集合时，出现下一个错误。如果我摆脱了“item.imagens=imgs”这一行，错误就消失了。
我究竟做错了什么？这个问题有什么解决方法吗？

var values="something....."
var sanit=values.replace(/(\r?\n|\r\n?)/g, "");
在Delphi中，我正在尝试下一个代码：
values="something....."
sanit:=TRegex.Replace(values,'/(\r?\n|\r\n?)/g', '');
但这是行不通的。没有替换完成。
