Javascript 节点红色UI模板如何清除缓存

嗨，我有一个像这样的UI模板节点

[{"id":"a5c1aeec.acf41","type":"ui_template","z":"317f5671.321bea","group":"7390bf6e.e7d18","name":"alert","order":0,"width":"","height":"","format":"<meta http-equiv=\"cache-control\" content=\"no-cache\" />\n<meta http-equiv=\"Pragma\" content=\"no-cache\" />\n<meta http-equiv=\"Expires\" content=\"-1\" />\n\n<div></div>\n<script>\n\n(function(scope) {\n    scope.$watch('msg', function(msg) {\n                alert(msg.payload);\n                 return msg;\n    });\n  \n})(scope);\n  \n</script>\n\n","storeOutMessages":false,"fwdInMessages":false,"templateScope":"local","x":930,"y":540,"wires":[[]]},{"id":"ea160087.f05fd","type":"inject","z":"317f5671.321bea","name":"","topic":"","payload":"hello","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":704,"y":539,"wires":[["a5c1aeec.acf41"]]},{"id":"7390bf6e.e7d18","type":"ui_group","z":"","name":"info","tab":"3b15c8d0.06c048","order":5,"disp":false,"width":"9","collapse":false},{"id":"3b15c8d0.06c048","type":"ui_tab","z":"","name":"config","icon":"settings","order":4}]

[{“id”：“a5c1aeec.acf41”，“type”：“ui_template”，“z”：“317f5671.321bea”，“group”：“7390bf6e.e7d18”，“name”：“alert”，“order”：0，“width”：“height”：“format”：“\n\n\n\n\n\n\n\n（函数（作用域）{\n作用域.$watch，“storeOutMessages”：false，“fwdInMessages”：false，“templateScope”：“local”，“x”：930，“y”：540，“wires”：[[]]}，{“id”：“ea160087.f05fd”，“type”：“inject”，“z”：“317f5671.321bea”，“name”：“topic”：“payloadType”：“hello”，“payloadType”：“str”，“repeat”：“crontab”：“once”：“一次”：false”，“OnPlay”：0.1”，“x”：704，“y”：539，“wires”：[“a5c1aeec.acf41”]，{“id”：“73906BFE.e7d18”}，”“：”ui_group“，”z“，”name“：”info“，”tab“：”3b15c8d0.06c048“，”order“，”disp“：”false“，”width“：”9“，”collapse“：false}，{”id“：”3b15c8d0.06c048“，”type“：”ui_tab“，”z“，”name“：”配置“，”图标“：”设置“，”order“：”4}]

当我重新加载页面时，虽然没有“msg.payload”传递给它，但这是使用以前的值执行的。

---

有谁能帮我清除缓存或重新加载时，这应该不会显示任何警报。

如果没有这样设置，您可以检查变量并跳过警报：

(function(scope) {
scope.$watch('msg', function(msg) {
            if(typeof(window.lastAlert)=="undefined"){
                window.lastAlert = msg;
            }else{
                alert(msg.payload);
            }
            return msg;
});

这在我使用chrome时起了作用。更新流后，可能必须清除浏览器缓存。（chrome中的Ctrl+F5）

很抱歉，它不工作。正常警报也不显示。您使用的浏览器/操作系统是什么？我使用的是chrome和windows 7，我已通过将标志存储在本地存储中解决了此问题。即，在一个模板中设置本地存储，在发出警报之前，我检查该标志是否为真，然后仅显示警报。
