[英]dynamic textbox jquery focus
i am creating a dynamic text box of input type with the help of following code i am not able to set the focus on the input type. 我正在以下代码的帮助下创建输入类型的动态文本框,我无法将焦点设置在输入类型上。
var elem = document.createElement("input");
elem.type = "text";
elem.id = "txtParent";
elem.setAttribute('onblur', 'SetSpanValueForParent("' + spnText.id + '")');
$(elem).focus();
$(spnText).append(elem);
i have also tried doing this elem.focus(); 我也尝试过这样做elem.focus();
can u provide that one line statement how can i achieve this 您能提供一条语句吗?
You first need to append the input, before setting the focus(). 在设置focus()之前,您首先需要附加输入。
Elements can have focus only if they are visible. 元素只有在可见时才能具有焦点。
Example: 例:
function fx(spnText)
{
var elem = document.createElement("input");
elem.type = "text";
elem.id = "txtParent";
elem.setAttribute('onblur', 'SetSpanValueForParent("' + spnText.id + '")');
$(spnText).append(elem);
//a little delay before setting the focus
setTimeout(function(){elem.focus()},50);
}
