确定输入框属性 [英] Determine Input Box Property

问题描述

我有一个脚本，只有当我的输入框不是

禁用时才能运行。有人能告诉我脚本是否有问题吗？

" disabled"正确使用的属性？


函数TextChanged（i）{

if（！document.ScheduleForm [" txtGrossPayroll" + i] .disabled）{

document.ScheduleForm.txtRecordStatus.value ="所做的改变;记录不是

已保存。" ;;

document.ScheduleForm.txtRecordStatus.style.color ="＃FF0000";

}

}

谢谢，

禁用正确使用的属性？

函数TextChanged（i）{
if（！document.ScheduleForm [" txtGrossPayroll" + i] .disabled）{
document.ScheduleForm。 txtRecordStatus.value ="所做的更改;记录不是
已保存。" ;;
document.ScheduleForm.txtRecordStatus.style.color ="＃FF0000" ;;
}
}

对我来说很好看。不满意它的运行方式？只是挑剔，但是对于txtRecordStatus元素的两次查找可以通过将其存储在临时变量中来有效地处理更多

：


function TextChanged（i）{

var sf = document.forms.ScheduleForm.elements;

if（！sf [" txtGrossPayroll" + i] .disabled） {

var rs = sf.txtRecordStatus;

rs.value ="所做的改变;记录未保存。;

rs.style.color ="＃FF0000" ;;

}

}

感谢您使用临时变量的信息。 br />

我发现了一个我用过的错误。而不是禁用，我将输入

设置为只读 - 因此公式应为：

if（！document.ScheduleForm [" txtGr * ossPayroll" + i] .readonly）


使用readonly会有什么不同吗？

完全没有，但请注意DOM属性区分大小写，

" readOnly"有一个大写O.

I have a script that I want to run only when my input box IS NOT
disabled. Can someone tell me if something is wrong with my script? Is
"disabled" the correct property to use?

function TextChanged(i){
if (!document.ScheduleForm["txtGrossPayroll" + i].disabled) {
document.ScheduleForm.txtRecordStatus.value = "Changes Made; Record Not
Saved.";
document.ScheduleForm.txtRecordStatus.style.color = "#FF0000";
}
}
Thanks,

Looks good to me. Not happy with how it runs? Just nitpicking, but the
two lookups into the txtRecordStatus element could be handled more
efficiently by storing it in a temporary variable:

function TextChanged(i){
var sf = document.forms.ScheduleForm.elements;
if ( !sf["txtGrossPayroll" + i].disabled ) {
var rs = sf.txtRecordStatus;
rs.value = "Changes Made; Record Not Saved.";
rs.style.color = "#FF0000";
}
}

Thanks for the information on using a temporary variable.

I found a mistake that I used. Instead of disabled, I have the input
set as readonly - therefore the formula should be :
if (!document.ScheduleForm["txtGr*ossPayroll" + i].readonly)

Does using readonly make any difference?

None at all, but note that the DOM properties are case-sensitive and
"readOnly" features a capital O.
