<div id="app">
<textarea rows="10" v-model="projectName" placeholder=""></textarea>
<!-- <input type="text" v-model="projectName" placeholder=""> -->
<button @click="search">click</button>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var vm = new Vue({
el: "#app",
data: {
projectName: ""
},
methods: {
search: function () {
alert(this.projectName == "");
}
}
});
</script>
</body>
</html>
key in one character such as "a" or paste a word and click search button in IE11, then you will get alert(true). But if you remove the placeholder attr, you will get false.
What is expected?
alert "false"
What is actually happening?
alert "true"
Because code.io is not supported in IE11, please manually type the code to reproduct the issue.
