利用jq的append()追加函数即可实现,如:
html:
<div class="main"><input type="button" value="添加" class="btn" />
</div>
JQ:
$(document).ready(function(){$(".btn").click(function(){
var html = '<div style="width:200px height:30px border:1px dashed red margin-bottom:20px"></div>'
$(".main").append(html)
})
})
jquery怎么在请求中添加authorization首先的首先,涉及业务逻辑的输入是需要通过参数传递的,主要有三种方法:path, query, POST/PUT body path: GET /api/user/123 其中的123通过path传递 query: GET /api/search_user?userId=123 body: POST /api/user-signup {username: 'john'} 不建议通过header传参的原因: 1. proxy 和 reverse proxy会drop header 2. 不利于传输object 3. HTTP access control (CORS) API 一般会设置Access-Control-Allow-Headers,分分钟教你做人。 4. 不利于dev和debug 5. Header长度限制 然后,如果你需要传header,比如Authorization,如下。 jQuery.ajax() headers (default: {}) Type: PlainObject An object of additional header key/value pairs to send along with requests using the XMLHttpRequest transport. The header X-Requested-With: XMLHttpRequest is always added, but its default XMLHttpRequest value can be changed here. Values in the headers setting can also be overwritten from within the beforeSend function. (version added: 1.5)$.ajax({ url: '/path/to/service', method: 'GET | POST | PUT | DELETE', headers: { 'Authorization': 'Bearer <jwt token>', 'some-other-header': 'some value' } }) .done(function(data){...}) .fail(function(jqXHR){...}) .always(function(){...})
