如何将复选框值从HTML发送到Node JS? [英] How to send checkboxes values from HTML to Node JS?
问题描述
我尝试将一些复选框值从HTML发送到Node JS。在我的HTML文件中,我在表格中有一些复选框。我得到了选中的复选框值,如下所示:
I tried to send some checkboxes values from HTML to Node JS. In my HTML file, I have some checkboxes in a table. I got the checked checkboxes values as following,
$("#createSS").click(function (event) {
event.preventDefault();
var searchIDs = $("#imgTable input:checkbox:checked").map(function () {
return $(this).val();
}).get();
console.log("selected::::" + searchIDs);
});
我的HTML表单是,
<form action="/addSlideShow" method="POST">
<table id="imgTable" class="table">
{{#images}}
<tr>
<td><input id={{imgURL}} type="checkbox" name="ch" value={{imgURL}}/></td>
</tr>
{{/images}}
</table>
<input id="createSS" type="submit" value="Create Slide Show" class="btn btn-success pull-left" disabled/>
</form>
在Node JS中,
app.post('/addSlideShow', function (req, res) {
var $ = req.body;
$('td').each(function () {
console.log($(this).text());
});
});
当我点击HTML中的按钮时,for不会提交。我该如何解决这个问题?
When I'm clicking the button in HTML, the for isn't submit. How may I fix this?

推荐答案
这是因为你不是将数据发布到表单网址。因为您使用了 event.preventDefault()
,它将永远不会提交,也不会使用 $。ajax()发布数据
This is because you are not posting the data to the form url. As you have used event.preventDefault()
which will never submit nor you used $.ajax() to post data
尝试使用ajax发布数据,
Try to post the data using ajax like,
$("#createSS").click(function (event) {
event.preventDefault();
var searchIDs = $("#imgTable input:checkbox:checked").map(function () {
return $(this).val();
}).get();
console.log("selected::::" + searchIDs);
$.ajax({
url:'/addSlideShow',type:'post',
data:{searchid:searchIDs},
success:function(response){
console.log(response);
}
});
});
在节点js中你会得到,
In node js you will get,
app.post('/addSlideShow', function(req, res) {
console.log(req.body); //Output=> like { searchid: 'Array of checked checkbox' }
console.log(req.body.searchid); // to get array of checked checkbox
});
