                        <input type="submit" value="Calculate" />   
                    </form>

我想验证2个输入字段,因此我使用http://livevalidation.com/中的livevalidation来摆脱那些丑陋的“警报”。

我现在的问题是我想在testfunction()中做一些计算,我不希望提交表单。我可以使用type =“button”而不是“submit”,但这样生活验证将无效。

所以当我输入类似

的内容时
function testfunction (myform) {

var odds = myform.odds.value;
var handicap = myform.handicap.options[myform.handicap.selectedIndex].value;
    //much more code here
    return false; }

它忽略了返回false并且表单被提交。如果我没有从表单获得输入的任何东西它工作正常。那么如何在提交时获得输入并返回false以便表单不会被提交?

答案 0 :(得分:1)

你能做的就是

  <input type="submit" value="Calculate" onclick="return (testfunction ('yourform'));" />

它会在调用函数时返回函数的返回值(false)。
