PHP/Javascript替换功能的构建

Question

我想请您帮助解决我的问题。 我有这个 php 代码，我用它来清除 $pname 中的介词、空格、数字等，使其更适合排序。

$prepositions = array(" ", "tert-", "dl-");         //only a part of  all
$patterns = array("'([0-9])'si", "/\b\w\b\s?/", "/[^a-zA-Z0-9\s]/");
$sname = preg_replace($patterns, '', str_replace($prepositions, "", strtolower($pname])));

我正在尝试将此代码转换为 JavaScript，但代码太大了。这是它的一部分：

function createsname ()
{
    if(document.getElementById('pname').value != '') 
    {
    var myString = new String();
    myString = document.getElementById('pname').value.toLowerCase();
    var reg0 = new RegExp(" ");
    var sname0 = myString.replace(reg0, "");
    var reg1 = new RegExp(/\d/g);
    var sname = sname0.replace(reg1, "");
    document.getElementById('sname').value = sname;
    }
}

因此，如果您有想法如何用 javascript 编写它，请帮助我。

Answer 1

var myString = document.getElementById('pname').value.toLowerCase();
var replaces  = [" ", "tert-", "dl-", /([0-9])/si, /\b\w\b\s?/, /[^a-zA-Z0-9\s]/];

for ( var k in replaces ) {
  myString = myString.replace(replaces[k], "");
}

布拉德·克里斯蒂提议：

for ( var k = 0; k < replaces.length; k++ ) {
  myString = myString.replaces(replace[k], "");
}

Answer 2

好吧，根据您提供的示例以及我可以测试的内容，这就是我得出的结果：

String.prototype.Lukas = function(){
    return this.toLowerCase().replace(/(\(.*?\)|\[.*?\]|\b\w\b\s?|(?:dl|tert|\d+[a-z]){1,4}-|\W|\d)/ig, '');
};

DEMO

再说一遍，仅基于我所看到的。像这样使用它：

// assign the original string to a variable
var original = '1,2,4-Triazolo-[4,3,a]pyridin-3(2H)-one';

// then get the desired result using "Lukas()"
var result = original.Lukas();
