How to enable/disable a text box on clicking a button
提问by Coding active
For example my page has a text box which already has some value and the readonly option for it is "true" , when the edit button is clicked next to the text box , the editing option in text box is enabled. How do I implement enabling the textbox when i click on a button.
例如我的页面有一个文本框，它已经有一些值，它的只读选项是“true”，当单击文本框旁边的编辑按钮时，文本框中的编辑选项被启用。单击按钮时如何实现启用文本框。
function func() {
$("input:button[name='button1']").click(function() {
$("#text11").val($(this).val()).attr("disabled", "disabled");
if($(this).val() != "") {
$("#text11").attr("disabled", "").focus();
}
});
}
<input type="text" name="text11" readonly="readonly" value="Editing is disabled">
<input type="button" value="edit" name="button1">
which is when I click this button , the readonly option in textbox should be disabled.How do I do that ?
这是当我单击此按钮时，应禁用文本框中的只读选项。我该怎么做？

basically you just want to add the attribute disabled to your element to stop users using it.
基本上，您只想将禁用的属性添加到您的元素以阻止用户使用它。
$('#disablebutton').click(function(){
$('#textfieldToClose').attr('disable');
});
<input type="text" name="text11" readonly="readonly" id="textfieldToClose">
<input type="button" value="edit" name="button1" id="disablebutton">
i believe this should work, haven't tested it mind.
我相信这应该有效，还没有测试过。
