textbox focus out

javascriptjquerytextboxfocus

提问by Santhosh

I need to focus out from the textbox when it focus in.

当它聚焦时,我需要从文本框中聚焦。

I try to set focus for outer div and its working fine in IE but not in mozilla.

我尝试为外部 div 设置焦点,并且它在 IE 中工作正常,但在 mozilla 中却没有。

How do I do this?

我该怎么做呢?

This is my current code:

这是我当前的代码:

<div id="outer"> <input type = "textbox" /></div> Onfocus: document.getElementById("outer").focus()

I have tried all the answers and not worked in all the browsers. And I combined all together in to it.

我已经尝试了所有答案,但并未在所有浏览器中工作。我把所有的东西都结合在一起。

  1. TextBox.readonly = true;
  1. TextBox.readonly = true;

OnFocus:

焦点:

  1. var curText = TextBox.value;TextBox.value = "";TextBox.value = curText;

  2. TextBox.blur();

  3. TextBox_Parent.focus()
  1. var curText = TextBox.value;TextBox.value = "";TextBox.value = curText;

  2. TextBox.blur();

  3. TextBox_Parent.focus()

And its working fine in all the browsers

它在所有浏览器中都能正常工作

I wonder what's the purpose of using a textbox in this case if the user can never write anything inside. Just add a disabled="disabled"attribute or readonly="readonly"(in case you want to post the value).

如果用户永远不能在里面写任何东西,我想知道在这种情况下使用文本框的目的是什么。只需添加一个disabled="disabled"属性或readonly="readonly"(如果您想发布该值)。

In HTML:

在 HTML 中:

<input type="text" onfocus="this.blur();" />

In JS:

在JS中:

document.getElementById("input1").onfocus = function () { this.blur(); }

Some elements cannot accept focus without being editable.

某些元素在不可编辑的情况下无法接受焦点。

Where is the point in that? JS would be (didn't test it):

这其中的重点在哪里?JS 将是(没有测试它):

$('#textbox').focusin(function() {
   $(this).focusout();
});

/*for textarea*/
$(document).ready(function() {
$('textarea[type="text"]').addClass("idleField");
$('textarea[type="text"]').focus(function() {
    $(this).removeClass("idleField").addClass("focusField");
    if (this.value == this.defaultValue){
        this.value = '';
    }
    if(this.value != this.defaultValue){
        this.select();
    }
});
$('textarea[type="text"]').blur(function() {
    $(this).removeClass("focusField").addClass("idleField");
    if ($.trim(this.value == '')){
        this.value = (this.defaultValue ? this.defaultValue : '');
    }
});

});

});

that's what I used on my form.

这就是我在表单上使用的内容。
