jquery输入掩码插件

Question

如何填充掩码后的最后两位数字？例如：XXXX99
所以，当我在第一个数字键应该是1XXX99

var autoPopulateNo = "\\9\\9" //how to put this after the mask? example XXXX99 
 

 
$("#number").inputmask({ 
 
"mask": "9999" + autoPopulateNo, 
 
clearMaskOnLostFocus: false, 
 
placeholder:"X", 
 

 
});

<form action=""> 
 
    <div> 
 
    <label for="number">Mask</label> 
 
    <input id="number" type="text"/> 
 
    </div> 
 
</form>

这种事情是这样simple.You只是追加您的变量与面具。

var autoPopulateNo = 56 
 
$("#number").inputmask({ 
 
"mask": "9999"+autoPopulateNo, 
 
clearMaskOnLostFocus: false, 
 
placeholder:"X", 
 

 
});
