问题描述
我想在Ajax .POST中传递标签/值对，但是找不到任何解决方案. Ajax .POST通常会发送ID/值对，但我无法更改ID，而是要发送标签/值对.我提供了部分表格.请帮忙.
$.ajax({
url:"allfields.php",
type:"POST",
// dataType:"json",
data: $("#frmRequest").serialize(),
success: function(msg){
alert("Form Submitted: "+ msg);
return msg;
},
error: function() {
alert('Error occured');
}
});
<body>
<form id="frmRequest" name="frmRequest" >
<div class="clearfix" id="idRequestDetails" >
<table width="809" border="0" id="tbl_data_1_1_1_1__" summary="Profile">
<tr>
<th width="156" scope="col"><label class="labelrequest" for="txtProfileName1__">Name</label>
</th>
<th width="74" scope="col"><label class="labelrequest" for="txtProfileUserID1__">User ID</label></th>
<th width="131" scope="col"><label class="labelrequest" for="txtSiteCost1__">Site Cost Centre</label></th>
<th width="182" scope="col"><label class="labelrequest" for="txtDetail1__">Additional Details</label></th>
</tr>
<tr>
<td><input type="text" name="txtProfileName1__" id="txtProfileName1__" tabindex="100" /></td>
<td><input name="txtProfileUserID1__" type="text" class="clearfix" id="txtProfileUserID1__" tabindex="110" size="8" /></td>
<td><input name="txtSiteCost1__" type="text" id="txtSiteCost1__" tabindex="220" size="8" /></td>
<td><textarea name="txtDetail1__" rows="1" id="txtDetail1__" tabindex="240"></textarea></td>
</tr>
</table>
</div>
</body>
解决方案
以下是示例:
HTML
<form>
<label>Label1</label><input type="text" value="1">
<label>Label2</label><input type="text" value="some">
</form>
jQuery
var dataToServer = [];
$('form label').each(function() {
dataToServer.push({
label: $(this).text(),
value: $(this).next().val()
});
});
console.log(data);
// output
// [ {label: 'Label1', value: '1'}, {label: 'Label2', value: 'some'}]

希望这可以为您提供一些指导.
根据commnet
AJAX部分
$.ajax({
url: "allfields.php",
type: "POST",
dataType:"json",
data: dataToServer, // send above data here
success: function(msg) {
alert("Form Submitted: " + msg);
return msg;
},
error: function() {
alert('Error occured');
}
});
最终射击
$('#submit').on('click', function() {
var dataToServer = [];
$('#frmRequest label').each(function(i, el) {
var temp= {},
label = $(this).text(),
value = $('#' + $(this).attr('for')).val();
temp[label] = value;
dataToServer.push(temp);
});
console.log(dataToServer);
});
I want to pass label/value pair in Ajax .POST but cannot find any solution. Ajax .POST normally send id/value pair but I cannot change my id and would like to send labels/value pair instead. I have provided partial form. Any help please.
$.ajax({
url:"allfields.php",
type:"POST",
// dataType:"json",
data: $("#frmRequest").serialize(),
success: function(msg){
alert("Form Submitted: "+ msg);
return msg;
},
error: function() {
alert('Error occured');
}
});
<body>
<form id="frmRequest" name="frmRequest" >
<div class="clearfix" id="idRequestDetails" >
<table width="809" border="0" id="tbl_data_1_1_1_1__" summary="Profile">
<tr>
<th width="156" scope="col"><label class="labelrequest" for="txtProfileName1__">Name</label>
</th>
<th width="74" scope="col"><label class="labelrequest" for="txtProfileUserID1__">User ID</label></th>
<th width="131" scope="col"><label class="labelrequest" for="txtSiteCost1__">Site Cost Centre</label></th>
<th width="182" scope="col"><label class="labelrequest" for="txtDetail1__">Additional Details</label></th>
</tr>
<tr>
<td><input type="text" name="txtProfileName1__" id="txtProfileName1__" tabindex="100" /></td>
<td><input name="txtProfileUserID1__" type="text" class="clearfix" id="txtProfileUserID1__" tabindex="110" size="8" /></td>
<td><input name="txtSiteCost1__" type="text" id="txtSiteCost1__" tabindex="220" size="8" /></td>
<td><textarea name="txtDetail1__" rows="1" id="txtDetail1__" tabindex="240"></textarea></td>
</tr>
</table>
</div>
</body>
解决方案
Here is an example:
HTML
<form>
<label>Label1</label><input type="text" value="1">
<label>Label2</label><input type="text" value="some">
</form>
jQuery
var dataToServer = [];
$('form label').each(function() {
dataToServer.push({
label: $(this).text(),
value: $(this).next().val()
});
});
console.log(data);
// output
// [ {label: 'Label1', value: '1'}, {label: 'Label2', value: 'some'}]
Hope this can give you some guideline.
According to commnet
AJAX part
$.ajax({
url: "allfields.php",
type: "POST",
dataType:"json",
data: dataToServer, // send above data here
success: function(msg) {
alert("Form Submitted: " + msg);
return msg;
},
error: function() {
alert('Error occured');
}
});
Final shot
$('#submit').on('click', function() {
var dataToServer = [];
$('#frmRequest label').each(function(i, el) {
var temp= {},
label = $(this).text(),
value = $('#' + $(this).attr('for')).val();
temp[label] = value;
dataToServer.push(temp);
});
console.log(dataToServer);
});
