嗨，我又有问题了。是否可以在剃须刀页面中基于 C# 值呈现 js 代码？我该怎么做？例如：

@{
    double numberA = (double)ViewData["someVal"];
}
<h1>SOME HTML</h1>
<script>

let myVal = "Number is small";
@if (numberA > 5) {            // C# code checking c# variable that comes via ViewModel fom server
    myVal = "Number is large"  // change js variable
}
console.log(myVal); // prints phrase to browser console based on what was received from backend
</script>

基本情况如上

【解决方案1】：

@可以帮你获取C#变量的值。你可以尝试使用下面的代码：

@{
    double numberA = (double)ViewData["someVal"];
}
<h1>SOME HTML</h1>
<script>
    let myVal = "Number is small";
    if (@numberA > 5) {
        myVal = "Number is large";
    }
    console.log(myVal);
</script>
