问题描述
I'm trying to collect the text from a text input in HTML to the methods section of my Vue file but can't seem to figure it out. I've spent a couple hours researching v-model and messing around with it but, I was either doing it wrong or it doesn't do what I thought it did. Here's my code:
<template>
<div id="app">
<Layout>
<input id="queryBox" placeholder="Enter your SQL query here." size="60"/>
<br>
<input type="submit" v-on:click="logSomething()">
</Layout>
</div>
</template>
<script>
export default {
data: () => {
return {
queryText: ""
}
},
methods: {
logSomething() {
console.log(this.queryBox)
}
}
}
</script>
I'm trying to send whatever the user inputs into queryBox to the logSomething() method upon the click of the submit button. Thanks in advance for any help!
Difference between single and double bracket in calling columns
I'm in the process of learning R and hoped for some clarification on something.
Given this dataframe:
myDataset <- data.frame("IDs" = rep(1:10,each = 5),
"session" = rep(1:5, times = 10),
"IV" = rnorm(50),
"DV" = rnorm(50))
What different uses would calling the first column from this dataframe have based on whether you used one set of brackets:
myDataset[1]
Or two sets of brackets:
myDataset[[1]]
They both give the same information, one in the form of the numbers listed in rows and the other in its original column form.
I'm just trying to understand why I might want to use one over the other.
解决方案
您可以使用 v-model 并映射queryText包含输入字段数据的变量。然后在点击时，使用事件并使提交不加载表单，只是为了避免加载页面。
<template>
<div id="app">
<Layout>
<input id="queryBox" v-model="queryText" placeholder="Enter your SQL query here." size="60"/>
<br>
<input type="submit" v-on:click="logSomething">
</Layout>
</div>
</template>
<script>
export default {
data: () => {
return {
queryText: ""
}
},
methods: {
logSomething(e) {
e.preventDefault()
console.log(this.queryText)
}
}
}
</script>
