我遇到了iOS / Safari / Chrome的一个奇怪的限制。 用户可以选择一个图像,并将filecontent粘贴到输入元素中。
两者的长度不相等。这是iOS限制吗?
L.users.importConfigurations = function(options) {
var target = null;
this._getInputFileElement = function() {
var that = this;
fileInput = $('<input type="file" accept="image/*" style="display:none;" capture="camera" />');
fileInput.change(function() {
that._handleFiles(fileInput);
});
return fileInput;
};
this.showFileSelectionDialog = function() {
var fileInput = this._getInputFileElement();
fileInput.click();
};
this._handleFiles = function(fileInput) {
var files = fileInput[0].files;
if (files && files.length) this._readFile(files[0]);
};
this._readFile = function(fileInfo) {
var that = this;
var reader = new FileReader();
reader.onload = function(e) {
that._uploadFile(e.target.result);
};
reader.readAsDataURL(fileInfo);
};
this._uploadFile = function(fileData) {
var fbValue = $(options.target).closest('.fileboxframe').find(".fileboxvalue");
if (fbValue && fbValue.length > 0) {
alert("Length before: " + fileData.length.toString());
fbValue.attr('src', fileData);
alert("Length after (Should be same): " + fileData.length.toString());
alert("Length after (Should be same): " + fbValue.attr("src").length.toString());
}
};
this.showFileSelectionDialog();
};
