我可以使用和AJAX调用在CFINPUT中加载范围属性的最大值吗？
我在
CFFORM
CFINPUT
<cfselect id="this" name="this" bind="cfc:Data.getThis()" bindonload="true" />
<cfselect id="that" name="that" bind="cfc:Data.getThat({p1})" />
<cfselect id="theOther" name="theOther" bind="cfc:Data.getTheOther({p1}, {p2})" />
<cfdiv
id="maxQty"
bind="cfc:Data.getMaxQty({itemId})" />
<cfinput
type="text"
id="qty"
name="qty" />
<cfdiv
id="itemId"
bind="cfc:Data.getItemId({this}, {that}, {theOther})" />
CFFORM
cfc:Data.getMaxQty({itemId})没有找到相关结果

或隐藏字段中，然后在JavaScript函数中访问该值，该函数在您提交表单时验证最小值/最大值：<script type="text/javascript"> <!-- function validateForm() { var maxQty = document.getElementById("maxQty").innerHTML; if (document.myForm.add_item_1.value < 1 || document.myForm.add_item_1.value > maxQty) { alert("Quantity must be an integer value between 1 and " + maxQty); return false; } return true; } //--> </script> <cfform name="myForm" method="post" action="myFormAction.csm" onsubmit="return validateForm();"> <cfdiv id="maxQty" bind="cfc:Data.getMaxQty({itemId})" />
