用javascript聚焦到列

问题描述

我们有一个包含多行输入的HTML表单.我们使用默认信息填充该表.我们希望用户在使用默认信息填充表单后，将注意力集中在第一个非空白列上.

我们将ASP.NET与用于插入5250屏幕并将其转换为ASP.NET网站的工具一起使用.这是其中两条输入线的样子.共有10个:

setCursorAtTheEnd(this，event)不起作用.

We have an HTML form with multiple lines of input. We populate this table with default information. We want to user to have focus on the first non-blank column after the form is popluated with the default information.

We are using ASP.NET with a tool that is interpeting our 5250 screens and converting them to ASP.NET web sites. Here is what 2 of the input lines look like. There is a total of 10:

setCursorAtTheEnd(this,event) is not working.

<mdf:DdsCharField id="RESPONC_DSC01" runat="server" onfocus="setCursorAtTheEnd(this,event)"
              CssClass="DdsCharField"
              Length="67"
              style=" POSITION: absolute; LEFT: 91px; TOP: 264px;"
              Alias="DSC01"
              Usage="Both"
              VirtualRowCol="12,10"
              ErrorMessageId="UMS0012 RWMSGF 74 : 74"
              Width="604px"
              TabIndex="5" />

            <mdf:DdsCharField id="RESPONC_DSC02" runat="server"
              CssClass="DdsCharField"
              Length="67"
              style=" POSITION: absolute; LEFT: 91px; TOP: 288px;"
              Alias="DSC02"
              Usage="Both"
              VirtualRowCol="13,10"
              Width="604px"
              TabIndex="6"  />

[edit]从OP的答案中移出了其他信息

我是团队项目的高级程序员.因此，此信息正在传递给我.我收到了以下更新:

下面的代码将光标定位在最后一个字符之后，但是现在我们希望它向右移动1个空格:
(代码只是后面的原始代码的重复)[/edit]

Java脚本:

[edit] Moved the additional information from OP''s answer here

I am working as a senior programmer on a team project. So this information is being passed to me. I received an update, which follows:

The code below positions the cursor after the last character but now we want it to go 1 space more to the right:
(code was just a repetition of the original that follows)[/edit]

Java script:

function setCursorAtTheEnd(aTextArea, aEvent) {
                  var end = aTextArea.value.length;
                  if (aTextArea.setSelectionRange) {
                      setTimeout(aTextArea.setSelectionRange, 0, [end, end]);
                  } else {
                      var aRange = aTextArea.createTextRange();
                      aRange.collapse(true);
                      aRange.moveEnd('character', end);
                      aRange.moveStart('character', end);
                      aRange.select();
                  }
                  //               aEvent.preventDefault();
                  return false;
              }
