解决ExtJs TextField maxLength后还是可以输入

Ext.form.TextField.prototype.size = 20; Ext.form.TextField.prototype.initValue = function() { if(this.value !== undefined){ this.setValue(this.value); }else if(this.el.dom.value.length > 0){ this.setValue(this.el.dom.value); } this.el.dom.size = this.size; if (!isNaN(this.maxLength) && (this.maxLength *1) > 0 && (this.maxLength != Number.MAX_VALUE)) { this.el.dom.maxLength = this.maxLength *1; } };

 

上面的 js 代码放在 ext-all.js后即可
