字符串替换回路

Question

我有以下代码，猜测字符串不会被替换出于某种原因，如果我尝试手动agreements.replace('{customername}', 'some string');一切工作正常。

var keywords = [ 
    { 
     key: '{customername}', 
     desc: 'Customer Name', 
     map: 'user_name' 
    }, 

    { 
     key: '{vesselname}', 
     desc: 'Customer Vessel Name', 
     map: 'vessel_name' 
    } 
    ]; 

    var parseData = { 
    user_name: "Some name", 
    vessel_name: "Some Vessel", 
    spot_title: "My Spot", 
    today: new Date().toDateString() 
    }; 

    var agreements = "{customername}, some customer, {vesslname} -> here"; 

    for(var i = 0; i < keywords.length; i++) { 
    console.log(keywords[i]['key'], parseData[keywords[i]['map']]); 

    agreements.replace(
     keywords[i]['key'], 
     parseData[keywords[i]['map']] 
    ); 
    } 

    alert(agreements); 

请忽略我加入一些细节，以及计算器使得它的要求，有趣的......

Answer 1

改变代码如下：

agreements = agreements.replace(
 
     keywords[i]['key'], 
 
     parseData[keywords[i]['map']] 
 
    );
