Replace characters in string array Javascript
提问by petehallw
I have defined and populated an array called vertices. I am able to print the output to the JavaScript console as below:
我已经定义并填充了一个名为vertices. 我可以将输出打印到 JavaScript 控制台，如下所示：
["v 2.11733 0.0204144 1.0852", "v 2.12303 0.0131256 1.08902", "v 2.12307 0.0131326 1.10733" ...etc. ]
However I wish to remove the 'v' character from each element. I have tried using the .replace()function as below:
但是我希望从每个元素中删除 'v' 字符。我尝试使用以下.replace()功能：
var x;
for(x = 0; x < 10; x++)
{
vertices[x].replace('v ', '');
}
Upon printing the array to the console after this code I see the same output as before, with the 'v's still present.
在此代码之后将数组打印到控制台时，我看到与以前相同的输出，但 'v 仍然存在。
Could anyone tell me how to solve this?
谁能告诉我如何解决这个问题？

Strings are immutable, so you just have to re-assign their value:
字符串是不可变的，所以你只需要重新分配它们的值：
vertices[x] = vertices[x].replace('v ', '');

Should be
应该
vertices[x]=vertices[x].replace('v ', '');
Because replace returnsvalue, and doesn't changeinitial string.
因为替换返回值，并且不会更改初始字符串。

vertices[x] = vertices[x].replace('v ', '');
