我正在尝试通过php&ajax将image
从html页面以modal
的形式从html页面上传到数据库,但是它不起作用,我不知道为什么,有人可以帮助我吗?
HTML页面
<form method="post" enctype="multipart/form-data">
<div class="row">
<div class="col-sm-4">
<label class="Modallabel">Photo:</label>
</div>
<div class="col-sm-8">
<div class="input-group input-group-sm" style="margin-top: -5px;">
<input type="file" id="fileUpload" name="fileUpload" style="color: #ffffff;"/>
</div><br>
</div>
</div>
</form>
<button type="button" class="btn btn-success btn-md" style="margin:0;width: 75px;" onclick="AddNewCustomer()">Add</button>
Javascript功能
function AddNewCustomer()
{
//Image upload
$(document).ready(function()
{
$(document).on('change', '#fileUpload', function() //NOT WORKING HERE
{
var property = document.getElementById("fileUpload").files[0];
var image_name = property.name;
var image_extension = image_name.split('.').pop().toLowerCase();
if (jQuery.inArray(image_extension, ['gif','png','jpg','jpeg']) == -1)
{
alert("invalid Image File");
}
var image_size = property.size;
if(image_size > 2000000)
{
alert("Image File Size is very big");
}
else
{
var form_data = new FormData();
form_data.append("fileUpload", property);
$.ajax
({
type:"POST",
url:"addNewCustomer.php",
processData: false,
cache: false,
contentType: false,
data:
{
'form_data':form_data
},
success: function(data){
if (data == "Success!")
{
sweetAlert("Data entered successfully!");
}
else if(data == "Exist")
{
sweetAlert("","Customer already exists!","error");
return false;
}
},
error: function(jqXHR, textStatus, errorThrown) {
console.log('ERROR', textStatus, errorThrown);
}
})
}
})
})
}
最佳答案
单击change
处的<button>
后,将附加onclick="AddNewCustomer()
事件。
您可以删除AddNewCustomer
函数,并在单击change
元素时在#fileUpload
元素上调用.btn
。
$(document).ready(function() {
$(document).on('change', '#fileUpload', function() {//do stuff})
$(".btn").on("click", function() {
$("#fileUpload").trigger("change");
});
});
