ExtJs4如何递归地禁用面板上的所有字段和所有按钮 [英] ExtJs4 how to disable all fields and all buttons on a panel recursively
问题描述
调用 panel.disable()
灰色,但按钮仍然可以点击。
同样的结果使 panel.cascade
具有禁用每个组件的功能。
正确的方法是什么?
如果您正在使用ExtJs 4.x ,这是您正在寻找的 -
myFormPanel.query ('.field,.button')。forEach(function(c){c.setDisabled(false);});
(根据您的表单的复杂性修改您的选择器,您只需使用.component即可禁用表单中的所有组件)
另请参见 - Ext.ComponentQuery
如果您使用 3.x ,则可以实现相同的在这两个步骤中效果 -
myFormPanel.buttons.forEach(function(btn){btn.setDisabled(true);} ); //禁用所有按钮
myFormPanel.getForm()。items.each(function(itm){itm.setDisabled(true)}); //禁用所有字段
I'm trying to disable all clickable, editable components on my panel.
Calling panel.disable()
grays it out, but buttons are still clickable.
The same result gives panel.cascade
with a function that disables each component.
What is the right way to do this?
If you are using ExtJs 4.x, this is what you are looking for -
myFormPanel.query('.field, .button').forEach(function(c){c.setDisabled(false);});
(Modify your selector based on the complexity of your form. You can just use .component and it will disable all component in your form)

If you are using 3.x, you can achieve the same effect in two steps like this -
myFormPanel.buttons.forEach(function(btn){btn.setDisabled(true);}); //disable all buttons
myFormPanel.getForm().items.each(function(itm){itm.setDisabled(true)}); //disable all fields
