java - 当我使用Java标记时，JSP内部的JavaScript无法正常工作

$( document ).ready(function() {
    console.log( "ready!" );
    var ilceler = "${ilceler}";
});

它不会显示“ Ready！”。进行控制台。当我用chrome调试时，我看到了

$( document ).ready(function() {
    console.log( "ready!" );
    var subChildList = "";
    ilceler = JSON.parse(" [
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxxxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxxx","fatherid":"66","fathertag":"il"},
{"id":"x","tag":"xx","name":"xxx xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xx\/xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxx","fatherid":"66","fathertag":"il"},
{"id":"xx","tag":"xx","name":"xxxx","fatherid":"66","fathertag":"il"}]");
});

我的数据是正确的，但是为什么此功能不起作用。
注意：我的数据包含UTF-8字符。
注意2：我可以使用字符串代替json。

var a = ${tag}
console.log(a) >> "It's my tag"

最佳答案

在我看来，您需要删除变量周围的引号。

所以应该

var ilceler = ${ilceler};

JSP / JSTL解释器将保留这些引号，因此您的对象将被视为String值而不是JSON对象。另外，如果第二个输出是浏览器中的输出，则可以看到它不是有效的JSON。
