1. 第一个功能是是支持剪切板粘贴上传，比如qq截图上传之类的。
这个是网上找的，并自己实现了代码：
-
<script>
-
(
function
() {
-
document.addEventListener('paste',
function
(e) {
-
var
items = ((e.clipboardData || window.clipboardData).items) || [];
-
var
file = null;
-
-
if
(items && items.length) {
-
for
(
var
i = 0; i < items.length; i++) {
-
if
(items[i].type.indexOf('image') !== -1) {
-
file = items[i].getAsFile();
-
break
;
-
}
-
}
-
}
-
-
if
(!file) {
-
alert('粘贴内容非图片！');
-
return
;
-
}
-
var
formData =
new
FormData();
-
formData.append('file', file);
-
-
var
xhr =
new
XMLHttpRequest();
-
xhr.onload =
function
() {
-
try {
-
var
result = JSON.parse(this.responseText);
-
if
(result.result === 'success') {
-
var
links = document.getElementById(
"links"
);
-
links.innerHTML += result.url +
"<br />"
;
-
-
var
bbscode = document.getElementById(
"bbscode"
);
-
bbscode.innerHTML +=
"[img]"
+ result.url +
"[/img]<br />"
;
-
-
var
markdown = document.getElementById(
"markdown"
);
-
markdown.innerHTML +=
"![]("
+ result.url +
")<br />"
;
-
-
var
html = document.getElementById(
"html"
);
-
html.innerHTML +=
"<img src=\""
+ result.url +
"\" /><br />"
;
-
}
else
{
-
alert('上传失败1');
-
}
-
} catch (e) {
-
alert('上传失败2');
-
}
-
};
-
xhr.onerror =
function
() {
-
alert('上传失败3');
-
};
-
xhr.open('POST', 'file.php', true);
-
xhr.send(formData);
-
});
-
})();
-
</script>
