问题描述
< table>< p>
< thead>
....
< / thead>
< tr>
< td>< input type =textname =n_timeid =5030c9261eca0value =2012/>< / td>
< td>< input type =textname =n_nameid =5030c9261eca0value =a name/>< / td>
< td>< textarea name =n_commentid =5030c9261eca0> bla< / textarea>< / td>
< / tr>
< / table>
现在,我需要使用 $。post
到我的PHP处理页面
看起来像
if($ _ POST ['data' ]){
$ array = json_decode($ _ POST ['data']);
$ b $ p
$ b 所以我需要得到我所有的表单元素,然后转换成JSON
这就是我所做的:
/ /假设我可以从我的预定义变量中获得5030c9261eca0 ...
$ my_array = $(#5030c9261eca0)。map(function(){return $(this).is(input)?$(this ).val():$(this).text();});
//现在转换
JSON.stringify($ my_array);
//转换失败:Uncaught TypeError:将循环结构转换为JSON
此错误
$ b
未捕获的TypeError:将循环结构转换为JSON
如何解决这个问题?
另外,如果我通过HTML表单调用HTTP post,我可以接收在PHP中如果我有一个HTML表单元素,如 $ _ POST ['n_name']
>,首先循环所有 tr $ c $>是否可以完成与上述相同的操作? c>,然后循环遍历所有 input,textarea
并将聚集的值推送到数组。 c $ c> var data = [];
$('table tr')。each(function(){
var row = {};
$(this).find('input,textarea')。each(function ){
row [$(this).attr('name')] = $(this).val();
});
data.push(row);
});
//现在你可以使用data:)
code> data :
[0] [n_time] = foo
[0] [n_name] = bar
[0] [n_comment] = 123
[1] [n_time] = foo
[1] [n_name] = bar
[1 ] [n_comment] = 123
...
jQuery:
$。post(test.php,{'mydata':data});
PHP:
foreach($ _ POST ['mydata'] as $ row){
echo $ row ['n_name'];
转换它到jQuery函数:
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $表$数据=函数(){
var data = [];
$(this).find('tr')。each(function(){
var row = {};
$(this)。 find('input,textarea')。each(function(){
row [$(this).attr('name')] = $(this).val();
});
});
返回数据;
}
})(jQuery);
$ b $ //用法:
$ .post(test.php,{'mydata':$('table')。tableData()});
i've got some form input elements in an html table like this:
<table>
<thead>
....
</thead>
<tr>
<td><input type="text" name="n_time" id="5030c9261eca0" value="2012" /></td>
<td><input type="text" name="n_name" id="5030c9261eca0" value="a name" /></td>
<td><textarea name="n_comment" id="5030c9261eca0">bla</textarea></td>
</tr>
</table>
now, i need to send this form data using $.post
to my PHP processing pagewhich looks something like
if($_POST['data']){
$array = json_decode($_POST['data']);
}
so i need to get all my form elements and somehow made then into JSON
and this is what i did:
// assume i can get 5030c9261eca0 from my predefined vars...
$my_array = $("#5030c9261eca0").map(function () { return $(this).is("input")?$(this).val():$(this).text(); } );
//now convert
JSON.stringify($my_array);
// the conversion failed with : Uncaught TypeError: Converting circular structure to JSON
this error poped up:
Uncaught TypeError: Converting circular structure to JSON
how do i fix this?
also, if i do regluar HTTP post via HTML forms, i can recieve form data like $_POST['n_name']
in PHP if i have a HTML form element with attribute n_name
, how can i accomplish the same with the above?
First loop through all tr
, then loop trought all input,textarea
and push gathered values to array.
var data = [];
$('table tr').each(function(){
var row = {};
$(this).find('input,textarea').each(function(){
row[$(this).attr('name')] = $(this).val();
});
data.push(row);
});
// now you can use "data" :)
Example data
:
[0][n_time] = foo
[0][n_name] = bar
[0][n_comment] = 123
[1][n_time] = foo
[1][n_name] = bar
[1][n_comment] = 123
...
jQuery:
$.post("test.php", { 'mydata': data } );
PHP:
foreach($_POST['mydata'] as $row) {
echo $row['n_name'];
}
It's good idea to convert it to jQuery function:
(function( $ ) {
$.fn.tableData = function() {
var data = [];
$(this).find('tr').each(function(){
var row = {};
$(this).find('input,textarea').each(function(){
row[$(this).attr('name')] = $(this).val();
});
});
return data;
}
})( jQuery );
// Usage:
$.post("test.php", { 'mydata': $('table').tableData() } );
