有没有办法通过Java脚本功能清除html表单内的输入文本并选择框字段?
最佳答案
这是我的答案...
function clearFields(formName)
{
var formElements = formName.elements;
for(var i=0;i<formElements.length;i++)
{
var elementType = formElements[i].type;
if('text' == elementType){
formElements[i].value="";
formElements[i].disabled = false;
}
else if('select-one' == elementType){
formElements[i].selectedIndex = 0;
formElements[i].disabled = false;
}
else if('select-multiple' == elementType)
{
var multiOptions = formElements[i].options;
for(var j=0;j<multiOptions.length;j++)
{
multiOptions[j].selected = false;
}
}
}
}
