ASP.Net对象和Javascript的问题 [英] Problems with ASP.Net object and Javascript
问题描述
我有一个功能：
功能SalaryDisplay（我）
{
var salaryMinLabel = document.getElementById（" ; SalaryMin"）;
salaryMinLabel.value = 200;
alert（"设置salaryMinLabel =" + salaryMinLabel.value之后）;
}
我还有一个asp.net对象：
< asp：label id =" SalaryMin" RUNAT = QUOT;服务器" />
呈现：
< span id =" SalaryMin">< / span>
该函数似乎找到了很好的范围。警告框显示它是
设置为200.但网页从不显示它。
设置span元素是否有问题？ />
谢谢，
Tom
I have a function:
function SalaryDisplay(me)
{
var salaryMinLabel = document.getElementById("SalaryMin");
salaryMinLabel.value = 200;
alert("after setting salaryMinLabel = " + salaryMinLabel.value);
}
I also have an asp.net object:
<asp:label id="SalaryMin" runat="server" />
Which renders into:
<span id="SalaryMin"></span>
The function seems to find the span fine. The alert box shows that it is
set to 200. But the web page never shows it.
Is there a problem setting the span element?
Thanks,
Tom

我只是将对象更改为一个asp：textbox，它会在屏幕上呈现输入字段
，这样可以正常工作。
在asp中，您使用标签对象在屏幕上显示（和更改）文本
，它不属于输入类型的字段。
有没有办法在Javascript / html中执行此操作？
我只是希望能够在
$ b上显示某些计算的结果用户输入的$ b字段只是一个标签。

I just change the object to an asp:textbox which renders into an input field
on the screen and this works fine.
In asp, you use a label object to display (and change) text on the screen
that is not part of an input type of field.
Is there a way to do this in Javascript/html?
I just want to be able to display the results of some calculations on a
field that the user inputs as just a label.
Thanks,

跨元素没有值。您需要创建一个新的文本节点然后
将它附加到元素以向其添加文本。查看DOM 1规范的JavaScript部分
。 http://w3.org/DOM/

Span elements don''t have values. You need to create a new text node then
append it to the element to add text to it. Look at the JavaScript section
of the DOM 1 specification. http://w3.org/DOM/

我试过做< lable>同样的事情标签项目和具有相同的
问题。它显示价值已经改变，但似乎没有在屏幕上显示任何内容：
每年补偿：<输入名称= " SalaryMin"类型= QUOT;文本" id =" SalaryMin"
/>& nbsp; /& nbsp;
< span id =" SalaryMax">< / span>
< Label id =" SalaryMin2" for =" SalaryMin">这是一个测试< / Label> />
javascript代码：
功能SalaryDisplay（我）
{
alert（" this.value =" + me.value）;
var salaryMinLabel = document.getElementById（" SalaryMin2"）;
salaryMinLabel。 innerText = 200;
alert（在设置salaryMinLabel =" + salaryMinLabel.value之后）;
}
这个好像不起作用。我试图直接这样做
（SalaryMin2.innerText = 200），但那也没办法。

I tried to do the same thing with the <lable> label item and had the same
problem. It shows that the value was changed, but it didn''t seem to do
anything on the screen:
Yearly Compensation:<input name="SalaryMin" type="text" id="SalaryMin"
/> /
<span id="SalaryMax"></span>
<Label id="SalaryMin2" for="SalaryMin">This is a test</Label> />
The javascript code:
function SalaryDisplay(me)
{
alert("this.value = " + me.value);
var salaryMinLabel = document.getElementById("SalaryMin2");
salaryMinLabel.innerText = 200;
alert("after setting salaryMinLabel = " + salaryMinLabel.value);
}
This doesn''t seem to work. I tried to do it directly
(SalaryMin2.innerText=200), but that didn''t work either.

我只是希望能够在一个
字段上显示一些计算结果，用户输入的只是一个标签。
