codePointAt 的 Coldfusion 等效函数

Question

在javascript中有一个函数codePointAt，其中returns一个数字表示给定索引处字符的代码点值。是否有类似于 codePointAt 函数的 UDF 或内置函数？

var icons = '☃★♲';

console.log(icons.codePointAt(0));
// expected output: "9733"

Answer 1

例如asc() in ColdFusion. The function only converts a single (the first) character though, so you have to extract the position of the desired character in a string by yourself, using mid()。

<cfscript>

    icons = '☃★♲';
    icon = mid(icons, 2, 1);

    writeOutput( asc(icon) );
    // expected output: "9733"

</cfscript>
