我想在同一个 HTML 表单中包含 DELETE 方法，调用相同的操作(调用 REST 服务)。我该怎么做呢 ？ 。我当前的 HTML 表单如下所示:DELETE 功能不起作用，但 POST 可以。我还包含了 REST 资源服务。如有任何建议，我们将不胜感激。
<!DOCTYPE html>
<html>
<head>
<title>Form to create a new resource</title>
<style>
tab { padding-left: 4em; }
</style>
</head>
<body>
<form id= "myForm" action="../com.dcr.jersey.first/rest/todos" >
<label for="id">ID</label>
<input name="id" />
<br/>
<label for="summary">Summary</label>
<input name="summary" />
<br/>
Description:
<TEXTAREA NAME="description" COLS=40 ROWS=6></TEXTAREA>
<br/>
<button type="submit" value="Submit">Submit</button> <tab> <button type="submit" value="Delete">Delete</button>
<script>
$("button.Submit").click(function(){
$("#myForm").attr("method", "POST");
});
$("button.delete").click(function(){
$("#myForm").attr("method", "DELETE");
});
</script>
</form>
</body>
</html>

最佳答案
不是名为“formmethod”的属性，也不是方法。 method 属性通常位于表单级别。尝试
$("#myForm").attr("formmethod", "POST");
相反
关于javascript - 如何在 REST 服务调用中包含相同 "action"的 HTML 表单 method=DELETE，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29944527/
