通过指定数组里面的val值来删除元素-------在无法通过index的情况下

//删除指定的元素
                    Array.prototype.indexOf =
function(val) {
                        for (var
i = 0;
i < this.length;
i++) {
                            if (this[i]
== val)
return i;
                        }
                        return
-1;
                    };

                    Array.prototype.remove =
function(val) {
                        var
index = this.indexOf(val);
                        if (index >
-1) {
                        this.splice(index,
1);
                        }
                    };
                    var emp = ['abs','dsf','sdf','fd']
                    emp.remove('abs');
                    console.log("数组删除之后的"+emp)
                    jibingdata.disease1.remove($(this).val())
