如何获取文本框的标题/工具提示... [英] How can I get the title/tooltip of a textbox...

问题描述

我正在尝试做一些非常简单但无法使其发挥作用的事情。



我需要获取工具提示的值并将其与当前文本框中的文本进行比较。我想在javascript中执行此操作，以便在将其发送到服务器之前发布客户端弹出确认。我似乎无法得到文本框。我已经尝试过使用jquery并且标题和innertext属性是空白的，即使我点击f12时，标题和值都在那里。

 function confirmHiredChange（ctrl）{
 debugger; 
  var  row = $（  tr [ ID = TRID]）; 
  var  tbHiredDtm = row.find（ 输入[ID $ = tbeRecruitHiredDtm]）; 
  if （tbHiredDtm [ 0 ]。title！=  ）
  return  真; 
  else   if （tbHiredDtm [ 0 ]。 value  ==  ）
  return   true ; 
 返回确认（' 你确定你想要更新__？'）; 
} 

执行onclientclick并返回确认。我只想显示先前未设置工具提示（string.empty）和文本值是否设置（！string.empty）。它找到了文本框，但无论我做什么，当我来到tbHiredDtm [0]时，两个属性都定义为，即使我点击f12它显示它们。



我知道这是我做错的小事，所以如果你看到我可以随意告诉我。或者，如果你知道一个更好的方式让我知道。

解决方案

（ tr [id = TRID]）;
var tbHiredDtm = row.find（ 输入[ID

= tbeRecruitHiredDtm]）;
if （tbHiredDtm [ 0 ]。title！= ）
return 真;
else if （tbHiredDtm [ 0 ]。 value == ）
return true ;
返回确认（' 你确定你想要更新__？'）;
}

在你的例子中（假设tbHiredDtm是你想要的标题）：

  var  title = 

I''m trying to do something extremely simple yet can not get it to work.

I need to get the value of a tooltip and compare it to the text that is currently in a textbox. I want to do it in javascript so that I can post a client-side pop up confirm before I send it to the server. I can''t seem get the textbox. I''ve tried using jquery and the title and innertext properties are blank even though when I hit f12, the title and value are there.

function confirmHiredChange(ctrl) {
        debugger;
        var row = $("tr[id=trid]");
        var tbHiredDtm = row.find("input[id$=tbeRecruitHiredDtm]");
        if (tbHiredDtm[0].title != "")
            return true;
        else if (tbHiredDtm[0].value == "")
            return true;
        return confirm('Are you sure you want to update this __?');
    }

this executes onclientclick and returns the confirm. I only want to show if the tooltip was previously not set (string.empty) and text value is set (! string.empty). It finds the textbox but no matter what I do, both properties are defined as "" when I come to tbHiredDtm[0] even though when I hit f12 it shows them.

I know it is something small that I am doing wrong, so if you see it feel free to let me know. Or if you know of a better way let me know that as well.

EDIT: TLDR- Basically how can I, in javascript, get the tooltip value of an asp:textbox ?

("tr[id=trid]"); var tbHiredDtm = row.find("input[id

=tbeRecruitHiredDtm]"); if (tbHiredDtm[0].title != "") return true; else if (tbHiredDtm[0].value == "") return true; return confirm('Are you sure you want to update this __?'); }

In your example (assuming tbHiredDtm is the what you want the title of) :

var title =
