修改inputText的值的onblur

Question

我JSF在我的项目PrimeFaces 5.1需要的onblur删除文本01,02,03,,或01,02,03或01,02,03,,,,该文本框的值我使用javascript可能需要01,02,03或任何其它方式

Answer 1

使用本trimRight指定字符即方法：https://www.sitepoint.com/trimming-strings-in-javascript/

String.prototype.trimRight = function(charlist) { 
 
    if (charlist === undefined) 
 
    charlist = "\s"; 
 

 
    return this.replace(new RegExp("[" + charlist + "]+$"), ""); 
 
}; 
 

 
console.log("01,02,03,,,".trimRight(','));

Answer 2

var input = "01,02,03,,,,"; 
//Keep checking if the trailing character is ',' 
while(input && input.charAt(input.length-1) == ","){ 
    //if true trim the last character and continue 
    input = input.substring(0,input.length-1); 
} 
console.log(input);
