如何在ui.bootstrap模式对话框的bodyText中设置格式（换行）

Question

I have in my AngularJS-script a ui.bootstrap confirmdlg:

var modalDlgOptions = {
  closeButtonText: "No",
  actionButtonText: "Yes",
  headerText: "my header text",
  bodyText: "my body text" 
};
confirmDlg.showModal({}, modalDlgOptions).then(function (result) {
  // todo something         
});     

This works fine. But now I want to format the bodyText. I need new lines like this:

first line in my body text
second line in my body text
...
last line in my body text

When I use

bodyText: "first line in my body text<br>second line in my body text<br>...<br>last line in my body text";

or

bodyText: "first line in my body text<br>second line in my body text<br>...<br>last line in my body text";

I get

first line in my body text<br>second line in my body text<br>...<br>last line in my body text

in output of my dialog, but not new lines .

Is it possible to format the bodyText of the confirmDlg and how?

Thank you for your hints, Thomas

Answer 1

I found this solution:

var modalDlgOptions = {
  closeButtonText: "No",
  actionButtonText: "Yes",
  headerText: "my header text",
  bodyText: "" 
};

confirmDlg.showModal({}, modalDlgOptions).then(function (result) {
  // todo something         
}); 

setTimeout(function() { 
  var modalBody = document.getElementsByClassName("modal-body");
  modalBody[0].innerHTML = "first line in my body text<br />second line in my body text<br /> ... <br />last line in my body text";
}, 100);    

Thanks for the comments, Thomas

Improving the previous solution:

var waitForElementByClassName  = function(element, timeout, callBack) {
      window.setTimeout(function(){
        if (document.getElementsByClassName(element)[0]){
          callBack(document.getElementsByClassName(element)[0]);
        } else {
            waitForElementByClassName(element, timeout, callBack);
        }
      }, timeout);
};

waitForElementByClassName("modal-body", 50, function(element) {
        element.innerHTML = "first line in my body text<br />second line in my body text<br /> ... <br />last line in my body text";
        });
