问题描述
知道 jQuery Caret 插件,我仍然看不到以下方法带有 JavaScript 的 HTML 中的单行文本框(即 input:type=text
控件):
Knowing the jQuery Caret plugin, I'm still seeing no way to do the following on a single line text box in HTML (i.e. the input:type=text
control) with JavaScript:
- 以编程方式将文本插入文本框
- 将插入符号设置到末尾.
- 使插入符号可见(即滚动文本框内容)
- Programmatically inserting text into a text box
- Setting the caret to the end.
- Making the caret visible (i.e. scroll the text box content)
我知道怎么做 1. 和 2.,只是为了 3. 我没有找到办法.
I know how to do 1. and 2., just for 3. I have found no way of doing it.
举例说明:
我的问题是:
有什么方法可以可靠地将插入符号放在文本的末尾并将其滚动到视图中?
Is there any way to reliable put the caret at the end of the text and scroll it into the view?
(我可以考虑模拟按下 END
键或类似的东西,但我不确定这是否是最佳选择).
(I can think of simulating pressing the END
key or something like that, but I'm unsure whether this would be the best option).
推荐答案
//hack to get cursor at end:
//hack to get cursor at end:
$(textboxselector).val($(textboxselector).val());
应该首先注意焦点:
$(textboxselector).val(newtext);
$(textboxselector).focus();
$(textboxselector).val($(textboxselector).val());
