[英]Replace characters in string array Javascript
I have defined and populated an array called vertices
. 我已经定义并填充了一个名为
vertices
的数组。 I am able to print the output to the JavaScript console as below: 我能够将输出打印到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. 但是我希望从每个元素中删除'v'字符。 I have tried using the
.replace()
function as below: 我尝试过使用
.replace()
函数,如下所示:
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. 在此代码之后将阵列打印到控制台后,我看到与之前相同的输出,并且'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?
字符串是不可变的,因此您只需重新分配它们的值:
vertices[x] = vertices[x].replace('v ', '');
Should be 应该
vertices[x]=vertices[x].replace('v ', '');
Because replace returns value, and doesn't change initial string. 因为replace 返回值,并且不更改初始字符串。
vertices[x] = vertices[x].replace('v ', '');
