jquery Ajax call Codeigniter Controller
提问by venky
In my View page jquery Ajax call like this
在我的视图页面中 jquery Ajax 调用是这样的
onclick: function() {
$.ajax({
type:'POST',
url:"<?PHP echo base_url('trand/report/checking'); ?>",
data: {nm:'vnky'},
success: function(){
alert("success");
},
error: function(){
alert("error");
}
});
chart2.exportChart({
type: 'image/png',
filename: dynmicfilename
});
}
exportchart function works perfectly .Inside ajax call also working alerts nice, but url is not executed, by using firebug when clicking the url in new tab , then it works fine.
exportchart 功能完美运行。在 ajax 调用中也可以很好地发出警报，但是 url 没有执行，通过在新选项卡中单击 url 时使用 firebug，然后它可以正常工作。
How can I execute url in ajax call. can you help on this ?

Here's my code. My controller return jsondata
这是我的代码。我的控制器返回json数据
$('.edit').click(function() {
$.ajax({
url: '<?php echo site_url('your_controller'); ?>',
type: 'POST',
data: {
key: value
},
dataType: 'json',
success: function(data) {
console.log(data);
}
});
});
Inside Ajax call, which alert is shown successor error? I think your JS code is correct. You should check your controller. If you open it in browser and it work fine. You should check csrf_protectionconfig is TRUE or FALSE
在 Ajax 调用中，哪个警报显示成功或错误？我认为您的 JS 代码是正确的。你应该检查你的控制器。如果你在浏览器中打开它并且它工作正常。您应该检查csrf_protection配置是 TRUE 还是 FALSE

function generate_dateOfBirth()
{
$data = $this->input->post('data', TRUE);
if (!empty($data))
{
// Check if the ID Number supplied is not less than 13 characters
if ( strlen(trim($data)) == 13)
{
$year = substr($data, 0, 2);
$month = substr($data, 7, 2);
$day = substr($data, 4, 2);
$dateOfBirth = $year .'/'. $month .'/'. $day ;
echo $dateOfBirth;
}
else
{
echo 'You have entered Invalid ID number above';
}
}
}
$('#id_number').on('change', function()
{
var dob = $(this).val();
$.ajax({
url: '/generate_date',
method: 'POST',
data: 'data=' + dob,
cache: false,
type: 'json',
success:function(data){
//update Increase month
$('#dob').val(data);
}
}); //End of ajax call
}); $route['generate_data'] = 'Controller Name/function in the controller doesn"t contain html';
