问题描述

问候，

我希望在文本框中替换从数据库中检索的值以进行数据更新。但是，我的代码无法正常工作，我不知道原因。有人可以帮我看一下吗？非常感谢你的帮助。



我的尝试：



< label for =Emp_Typeclass =col-sm-2 col-sm-push-1 control-label>员工类型< span> *< / span> < /标签>

< div class =col-sm-2style =padding-left：8％; width：250px>

< / select>

< / div>



< input type =textclass =form-controlstyle =width：120px; padding-left：1％id =pay name =payvalue =<？php echo $ payType？> readonly required>





function changetextbox（）

{

if（ document.getElementById（type）。value ===Full Time）

{

//替换付款类型的价值

var str = document.getElementById（pay）。value =;

var res = str.replace（，每小时）;

document.getElementById（pay）。value = res;

}

}

Greetings,
I wish to replace the value retrieve from database in a textbox for data update. However, my codes cannot work properly and I don't know the reason. Can some one help me to look on it? Appreciate the help very much.

What I have tried:

<label for="Emp_Type" class="col-sm-2 col-sm-push-1 control-label">Employee Type <span> * </span> </label>
<div class="col-sm-2" style="padding-left:8%;width:250px">
<select class="form-control" name="type" id="type" onChange="changetextbox()"/>
</select>
</div>

<input type="text" class="form-control" style="width:120px;padding-left:1%" id="pay" name="pay" value="<?php echo $payType?>" readonly required>


function changetextbox()
{
if (document.getElementById("type").value === "Full Time")
{
//replace value of Pay Type
var str = document.getElementById("pay").value = "";
var res = str.replace("", "Hourly");
document.getElementById("pay").value = res;
}
}

推荐答案

payType？>readonly required>





函数changetextbox（）

{

if（document.getElementById（type）。value ===全职）

{

//替换支付类型的价值

var str = document.getElementById（pay）。value = ;

var res = str.replace（，每小时）;

document.getElementById（pay）。value = res;

}

}

payType?>" readonly required>


function changetextbox()
{
if (document.getElementById("type").value === "Full Time")
{
//replace value of Pay Type
var str = document.getElementById("pay").value = "";
var res = str.replace("", "Hourly");
document.getElementById("pay").value = res;
}
}
