javascript - 符号之间的字符串替换？

我有一个这样的对象:

myDataObject = {
    name : 'Nikola Tesla',
    birth : ['10 July 1856','10. Juli 1856'],
    nation : ['Serbian','Serbisch'],
    knownFor : ['Alternating current',' Zweiphasenwechselstrom']
}

还有两个这样的字符串模式:

var englishStr = '#name#, born #birth[1]# , #nation[1]# best known for his contributions to #knownFor[1]#';

var deutschStr = '#name#, geboren #birth[2]#, #nation[2]# Erfinder, der für seine Beiträge zur #knownFor[2]# bekannt';

现在，我想替换标记为#properties#的代码。

如果没有像[1]或[2] smth这样的多语言指示器，我可以轻松地做到。与此类似:

$.each(myDataObject , function(n, v){
    englishStr = englishStr.replace('#'+ n +'#' , v )
});

那么，我该如何处理#prop[i]#？谢谢

最佳答案

一种方法是从字符串到数据对象，而不是遍历所有键。

var myDataObject = {
    name : 'Nikola Tesla',
    birth : ['10 July 1856','10. Juli 1856'],
    nation : ['Serbian','Serbisch'],
    knownFor : ['Alternating current',' Zweiphasenwechselstrom']
};
var englishStr = "#name#, born #birth[1]# , #nation[1]# best known for his contributions to  #knownFor[1]#";




var re = /#([^\[#]+)\[?(\d+)?\]?#/;  //Looks for #STRING# or #STRING[NUMBER]#
var test;
while ( (test=re.exec(englishStr))!==null) {  //Keep looking for matches in the string
    var key = test[1];   //get the key to the object
    var index = test[2]; //get the index if there
    var item = myDataObject[key];  //get reference to the item in the object
    if (index!==undefined && item) {  //if we have an index, look up the value from array
        index = parseInt(index,10)-1;  //arrays are zero index, so need to subtract one
        item = item[index];  //get the string
    }
    englishStr = englishStr.replace(re, item || "N/A");  //make the replacement in the string with the data from the object
};
