### <span id="SplitAndTrim">SplitAndTrim</span>
<p>将字符串str按字符串delimiter拆分为一个切片，并对该数组的每个元素调用Trim。忽略Trim后为空的元素。</p>
<b>函数签名:</b>
```go
func SplitAndTrim(str, delimiter string, characterMask ...string) []string
```
<b>示例:</b>
```go
import (
"fmt"
"github.com/duke-git/lancet/strutil"
)
func main() {
str := " a,b, c,d,$1 "
result1 := strutil.SplitAndTrim(str, ",")
result2 := strutil.SplitAndTrim(str, ",", "$")
fmt.Println(result1)
fmt.Println(result2)
// Output:
// [a b c d $1]
// [a b c d 1]
}
```
### <span id="HideString">HideString</span>
<p>使用参数`replaceChar`隐藏源字符串中的一些字符。替换范围是 origin[start : end]。</p>
<b>函数签名:</b>
```go
func HideString(origin string, start, end int, replaceChar string) string
```
<b>示例:</b>
```go
import (
"fmt"
"github.com/duke-git/lancet/strutil"
)
func main() {
str := "13242658976"
result1 := strutil.HideString(str, 3, 3, "*")
result2 := strutil.HideString(str, 3, 4, "*")
result3 := strutil.HideString(str, 3, 7, "*")
result4 := strutil.HideString(str, 7, 11, "*")
fmt.Println(result1)
fmt.Println(result2)
fmt.Println(result3)
fmt.Println(result4)
// Output:
// 13242658976
// 132*2658976
// 132****8976
// 1324265****
}
```
### <span id="ContainsAll">ContainsAll</span>
<p>判断字符串是否包括全部给定的子字符串切片。</p>
<b>函数签名:</b>
```go
func ContainsAll(str string, substrs []string) bool
```
<b>示例:</b>
```go
import (
"fmt"
"github.com/duke-git/lancet/strutil"
)
func main() {
str := "hello world"
result1 := strutil.ContainsAll(str, []string{"hello", "world"})
result2 := strutil.ContainsAll(str, []string{"hello", "abc"})
fmt.Println(result1)
fmt.Println(result2)
// Output:
// true
// false
}
```
### <span id="ContainsAny">ContainsAny</span>
<p>判断字符串是否包括给定的子字符串切片中任意一个子字符串。</p>
<b>函数签名:</b>
```go
func ContainsAny(str string, substrs []string) bool
```
<b>示例:</b>
```go
import (
"fmt"
"github.com/duke-git/lancet/strutil"
)
func main() {
str := "hello world"
result1 := strutil.ContainsAny(str, []string{"hello", "world"})
result2 := strutil.ContainsAny(str, []string{"hello", "abc"})
result3 := strutil.ContainsAny(str, []string{"123", "abc"})
fmt.Println(result1)
fmt.Println(result2)
fmt.Println(result3)
// Output:
// true
// true
// false
}
