问题描述
在利用表单向后台提交数据时,前端页面报错:
Refused to execute inline script because it violates the following Content Security Policy directive: “default-src ‘self’”. Either the ‘unsafe-inline’ keyword, a hash (‘sha256-2/nwTfnmhsEOQ+pVDGpNeMyOzp4HRtQri8QvvBb+A6Q=’), or a nonce (‘nonce-…’) is required to enable inline execution. Note also that ‘script-src’ was not explicitly set, so ‘default-src’ is used as a fallback.
解决方案
在前端表单提交时请勿采用type="submit"
的方式,而应采用type="button"
。
示例代码
在此,以示例形式展示解决方案。
html代码
<form method="post" id="userform2">
姓名: <input type="text" id="name" name="username" style="width: 150px" />
<br /><br />
年龄: <input type="text" id="age" name="userage" style="width: 150px" />
<br /><br />
<input id="ajaxPostButton4" type="button" value="利用$.post()提交表单" />
</form>
javascript代码
//利用$.post()提交表单
$("#ajaxPostButton4").click(function() {
var url = "http://xxx.xxx.137.1:8080/MyController/test";
var params = $("#userform2").serialize();
console.log(params);
$.post(
url,
params,
function(data) {
console.log(data);
},
"json"
);
});
