Sweet Alert 2在父框架中打开 [英] Sweet Alert 2 Open in Parent Frame
问题描述
我有一个iframe，其源代码是php文件.我想做的是让Sweet Alert 2在父框架中打开，而不是在iframe中打开.我尝试更改目标，但没有成功.
I have an iframe with a source that is a php file. What I'm trying to do is get Sweet Alert 2 to open in the parent frame rather than inside of the iframe. I have tried changing the target and have not had any success.
以下目标选项均无效:
swal({
target: 'window'
target: 'document'
target: 'parent'
});
这是我以身体"为目标时得到的结果:
This is the result that I get when 'body' is the target:
SweetAlert 2代码
SweetAlert 2 code
swal({
type: 'error',
text: 'You did not select any files.',
target: 'top'
});
iFrame代码
<div id="viewWindow" class="col-xs-10 content">
<iframe id="waiverList" src="php/edit_archive.php"></iframe>
</div>
推荐答案
您好，您可以做的是在您的父窗口中保存sweetalert2代码.然后，在iframe中使用JavaScript的parent属性来调用该函数.为避免出现相同的原始策略错误，您可以使用窗口发布消息.
Hi what you can do is have your sweetalert2 code in your parent window. Then use JavaScript's parent property inside your iframe to call the function. To avoid getting a same origin policy error you can use window post messages.
像这样:
父本
<!DOCTYPE html>
<html>
<body>
<script>
function openAlert() {
swal(
'Good job!',
'You clicked the button!',
'success'
)
}
window.addEventListener("message", function(event) {
if(event.data == "openAlert");{
openAlert();
}
});
</script>
<iframe src="iframe.html">
</iframe>
</body>
</html>
iframe HTML
<!DOCTYPE html>
<html>
<body>
<button onclick="foo();">Click Me</button>
<script>
function foo(){
parent.postMessage("openAlert", "*");
}
</script>
</body>
</html>
