[英]How to parse html response from fetch() API to iframe
I am trying to display a web page into an iFrame using fetch() API, where I get the url from the user and then display the page into an iFrame as if it is locally hosted, so that I can use javascript to work on the iFrame 的页面没有跨域问题。
我正在寻找的是使用 srdoc 将响应重定向到 iframe 中。
html 页面的代码如下:
<form method="POST">
<iframe id="frame" style="resize: both;width: 350px; height:500px;"></iframe>
<button type="button" onClick="retrieve()">Retrieve</button>
</form>
</div>
<div id="textarea">
<textarea id="` + tab_id + `" class="form-control" placeholder="Enter your source text here..." rows="20" onchange="change_textarea('` + tab_id + `')" onfocus="set_focus(this)" style="resize: vertical; min-height:35px;" readonly></textarea>
</div>
</div>
</form>
这是 javascript function:
function retrieve(){
let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');
headers.append('Origin', 'http://localhost:8080');
headers.append('Access-Control-Allow-Origin', 'http://localhost:8080');
headers.append('Access-Control-Allow-Credentials', 'true');
console.log(headers);
url = document.getElementById("tt").value;
fetch(url, {
mode: 'no-cors',
credentials: 'include',
method: 'POST',
headers: headers
})
.then((response) => {
document.getElementById("frame").srcdoc = response;
})
}
显然,通过解析响应我没有得到结果,而只是 "[Object Response]"; 关于如何解析从 fetch API() 到 iFrame 的响应的任何建议?
.then((response) => {
return response.text();
})
.then((text) => {
document.getElementById("frame").srcdoc = text;
})
