添加'到每個數組值的開始和結束

Question

我想添加到每個數組值的結尾和開始。這是因爲我有一個圖JQuery設置並想要操縱圖表值名稱。如果我想讓它們成爲數字，我可以做得很完美，但是每當我嘗試使用文本時，我會得到一個錯誤，我相信這是因爲在數組值的開始和結尾處沒有任何'錯誤。任何想法傢伙？

我得到的錯誤是

Uncaught ReferenceError: MyTextValue is not defined

var barNames = []; 

if (NoOfBars >= 1){ 
    barNames = [name1]; 
} 
if (NoOfBars >= 2){ 
    barNames = [name1, name2]; 
} 
if (NoOfBars >= 3){ 
    barNames = [name1, name2, name3]; 
} 
if (NoOfBars >= 4){ 
    barNames = [name1, name2, name3, name4]; 
} 
if (NoOfBars >= 5){ 
    barNames = [name1, name2, name3, name4, name5]; 
} 
if (NoOfBars >= 6){ 
    barNames = [name1, name2, name3, name4, name5, name6]; 
} 
if (NoOfBars >= 7){ 
    barNames = [name1, name2, name3, name4, name5, name6, name7]; 
} 
if (NoOfBars >= 8){ 
    barNames = [name1, name2, name3, name4, name5, name6, name7, name8]; 
} 
if (NoOfBars >= 9){ 
    barNames = [name1, name2, name3, name4, name5, name6, name7, name8, name9]; 
} 
if (NoOfBars >= 10){ 
    barNames = [name1, name2, name3, name4, name5, name6, name7, name8, name9, name10]; 
} 

var bar = new RGraph.Bar({ 
    id:'cvs1', 
    data: barValue, 
    options: { 
     backgroundGridDashed: true, 
     labels: barNames, 
     title: 'Title of Chart', 
     strokestyle: 'rgba(0,0,0,0)', 
     textAccessible: true 
    } 
}).draw();

喜歡的東西...

barNames = [ 
    "name1", "name2", "name3", "name4", "name5", 
    "name6", "name7", "name8", "name9", "name10" 
].slice(0,NoOfBars); 

這真的取決於這些值是如何使用的。
