[英]label text updated through javascript but not reflected on webpage
我正在一個具有多個下拉控件的頁面上,在每個下拉選擇的索引更改事件上,我想在模式彈出窗口中顯示一些消息,因此我在模式彈出窗口上顯示了帶有標簽的標簽,並從后面的代碼動態更改了標簽值調用JS函數,值會更改,但不會反映在網頁上。 這是代碼片段:
C#代碼:
public void Page_Load(object sender, EventArgs e)
{
//builds page controls
this._BuildControls();
if (IsPostBack)
{
// get the target of the post-back, will be the name of the control
// that issued the post-back
string eTarget = Request.Params["__EVENTTARGET"].ToString();
//source database server dropdown changes event called
if (eTarget.Contains("SourceDatabaseServer"))
{
this._DisplayMessage = "Loading source database...";
}
else if (eTarget.Contains("SourceDatabaseName"))
{
this._DisplayMessage = "Loading source host name...";
}
else if (eTarget.Contains("DestinationDatabaseServer"))
{
this._DisplayMessage = "Loading destination database...";
}
else if (eTarget.Contains("DestinationDatabaseServer"))
{
this._DisplayMessage = "Loading destination host name...";
}
else
{
this._DisplayMessage = "Cloning portal...";
}
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "script", "updateMessage('" + this._DisplayMessage + "');", true);
}
}
Javascript文件功能:
function updateMessage(message){
var text = document.getElementById('LoadAndSaveClonePortalDataModalModalPopup');
text.innerHTML=message;
}
您應該在模態形式中有一個標簽。
function updateMessage(message) {
var $modal = $('#LoadAndSaveClonePortalDataModalModalPopup'),
$messagelbl = $modal.find('#lblMessage');
$messagelbl.val(message);
$modal.modal("show");
}
