无法在JSP中显示期望值 [英] Unable to display expected value in jsp

问题描述

i在javascript中将值四舍五入为.25，.50，.75和.00.代码如下.

i was rounding off the value to .25,.50,.75 and .00 in the javascript. and the code is as below.

function roundOff(obj) {
    //alert(document.getElementById("sample").value);
    var val=obj.value;
    var newValue;

    var floorValue = Math.floor(val);
    var remainder = val - floorValue;
    if (remainder < 0.325) {
        if (remainder < 0.125) {
            newValue = floorValue;

        } else {
            newValue = floorValue + 0.25;
        }
    } else {
        if (remainder < 0.625) {
            newValue = floorValue + 0.5;
        } else if (remainder < 0.875) {
            newValue = floorValue + 0.75;
        } else {
            newValue = floorValue + 1;
        }
    }
    alert(floorValue);

        alert(newValue);
        document.getElementById("sample").value=newValue;

    //return obj;
}

，但是无法将值放回jsp页面.如果我输入5.5，则jsp中仅显示5.但是，如果我发出警报并检查floorvalue的值，则为5.5.但是如果我将它放在jsp的文本框中，它只给出5.为什么会这样?

but am not able to put the value back to the jsp page. if i type 5.5, only 5 is displayed in the jsp. but if i put alert and check the value of floorvalue then it is 5.5. but if i put it to the textbox in jsp it is giving only 5. why is it so???

推荐答案

我在jsp中使用了onKeyUp，这引起了麻烦.相反，我将其更改为onBlur，因为它提供了与我的要求相同的效果.谢谢"nnnnnn"的建议.现在可以正常工作了.

I was using onKeyUp in the jsp which was causing the trouble. instead i changed it to onBlur as it was providing the same effect as per my requirement. And thank you 'nnnnnn' for your suggestion. Its working now.
