我试过什么?
var specialChars = "!@#$^&%*()+=-[]/{}|:<>?,.";
for (var i = 0; i < specialChars.length; i++) {
stringToReplace = stringToReplace .replace(new RegExp("\" + specialChars[i], 'gi'), '');
}
但什么也没发生。
这是文件:
function clicked() {
document.getElementById("data").innerHTML =
"Fethching Score and Ranking <br>loading...";
var xhr = new XMLHttpRequest();
var url = document.getElementById("url").value;
if (url == "") {
alert("Please enter URL");
return;
}
var xhr = new XMLHttpRequest();
xhr.open(
"GET",
"https://www.googleapis.com/pagespeedonline/v1/runPagespeed?screenshot=false&strategy=mobile&url=" +
encodeURIComponent(url)
);
xhr.onload = function() {
document.getElementById("data").innerHTML = xhr.responseText;
};
xhr.send();
}
<input type="text" placeholder="Enter URL with http:// or https://" id="url" class="form-control"/>
<p>with <code>http</code> or <code>https</code></p>
<input type="button" value=" ENTER " onclick="clicked();"/>
<pre id="data"></pre> <!--output json here-->
我想我在将代码放在哪里以删除输出上的特殊字符方面有一些错误。
你能不能只使用
.replace(/[!@#$^&%*()+=[]/{}|:<>?,.\-]/g, '')
这将立即替换所有无效字符。
let str = '<pre> --all special character @#$%&*()\??><{}[]</pre>'
str = str.replace(/[!@#$^&%*()+=[]/{}|:<>?,.\-]/g, '')
console.log(str)
这是你想要的,不是吗?
function clicked() {
document.getElementById("data").innerHTML =
"Fethching Score and Ranking <br>loading...";
var xhr = new XMLHttpRequest();
var url = document.getElementById("url").value;
if (url == "") {
alert("Please enter URL");
return;
}
var xhr = new XMLHttpRequest();
xhr.open(
"GET",
"https://www.googleapis.com/pagespeedonline/v1/runPagespeed?screenshot=false&strategy=mobile&url=" +
encodeURIComponent(url)
);
xhr.onload = function() {
document.getElementById("data").innerHTML = xhr.responseText.replace(/[!@#$^&%*()+=[]/{}|:<>?,.\-]/g, '');;
};
xhr.send();
}
<input type="text" placeholder="Enter URL with http:// or https://" id="url" class="form-control"/>
<p>with <code>http</code> or <code>https</code></p>
<input type="button" value=" ENTER " onclick="clicked();"/>
<pre id="data"></pre> <!--output json here-->
