Question

我坚持一个条件：

替换特定序列，例如MA，仅当MA不在字母表之前或成功时才会显示空白字符串。

例如：

输入字符串：

string abc= "This is a MAin method with MA .Use your MA and MAt it "

输出字符串：

string result = "This is a MAin method with .Use your and MAt it "

注意：我写了MA大写字母以便澄清。我们必须使用jQuery。

Answer 1

你不需要jQuery，只需要一个简单的Javascript RegExp：

var input = "This is a MAin method with MA .Use your MA and MAt it ",    
    output = input.replace(/([^A-Za-z])(MA)([^A-Za-z])/g, '$1$3');

RegExp中的[^A-Za-z]表示“不是字母字符”，就像你在问题中所说的那样。如果您还想包含数字，可以添加0-9。如果您不关心MA是大写还是小写，请改为使用/ig结束您的RegExp。

Answer 2

您应该可以使用MA\s([^a-zA-Z]+)

之类的RegEx

然后在javascript（不需要jquery）中执行以下操作：

var abc = 'This is a MAin method with MA .Use your MA and MAt it ';
var result = abc.replace(/MA\s*([^a-zA-Z]+)/g, '$1')
console.log('We want: This is a MAin method with .Use your and MAt it');
console.log('We got:  ' + result);

您将获得以下输出：

We want: This is a MAin method with .Use your and MAt it
We got:  This is a MAin method with .Use your  and MAt it

所以空间太大，但你应该可以用一个简单的result = result.replace(' ', ' ');替换它

Answer 3

var input = "This is a MAin method with MA .Use your MA and MAt it ";

output = input.replace('MA ', '');

使用jQuery替换字符串
