Question

我想在mouseup上获取选定的文本。

我也尝试过

html代码

setTimeout(() => {
  var selectedData = contentWrapper.getSelection().toString();
  alert(selectedData)
}, 1008)

js代码

<iframe src="url"></iframe>

Answer 1

通过这种方式，它可以在IE，Chrome和FF（在本地测试）中工作，但在这里我无法触摸iframe。

Create Table ods.CustomerId(
ScreenDate INT NOT NULL,
CustomerNum nvarchar(40) NOT NULL,
MainAccountNum nvarchar(40) not null,
ServiceNum nvarchar(40) not null,
StartDate datetime not null,
EndDate datetime not null,
UpdatedBy nvarchar(50) not null);

function showSelection() {
  var selectedData = document.getSelection().toString();
  alert(selectedData)
}

var contentWrapper;
function attachIF() {
  if(location.href == "https://stacksnippets.net/js") return;
  var ifr = document.createElement("iframe");
  ifr.src="javascript:'"+ // Access is denied. Here on stackoverflow.com
    "<script>window.onload=function(){"+
      "document.write(\\'<script>if(document.domain)document.domain=\\\""+document.domain+"\\\";"+
      "document.write(\""+parent.document.body.innerText+"\");"+
      "<\\\\/script>\\');"+
      "document.close();"+
      "parent.contentWrapper = document;"+
      "document.body.onmouseup=parent.CheckSelections;"+
      "};<\/script>'";
  document.body.appendChild(ifr);
}

function CheckSelections() {
  var selectedData = contentWrapper.getSelection().toString();
  alert(selectedData)
}

document.getSelection（）。toString（）在使用iframe时即始终为“”
