My current goal involves achieving the following task.
In a certain variable, I currently have this text:
let text = 'hey this is a super long phrase'I am looking to utilize a label to showcase the text, but with only a limited number of characters displayed.
Specifically, for my text variable, I aim to show only 5 characters.
<label>{{text}}</label> //display the full textFurthermore, I wish to implement something similar to the following:
<label>{{text}}</label> //display only hey tThe method you use depends on the version of Vue you have. In Vue 2, you could utilize filters (or pipes):
filters: {
short: function (value) {
return value.substr(0, 5); // just an example
}
}
Then, you could do:
<label>{{ text | short }}</label>
In Vue 3, you can simply create a computed property (which was also an option in Vue 2, filters were just another approach for that):
computed: {
shortText() {
return this.text.substr(0, 5)
}
}
// if using Composition API
const shortText = computed(() => text.value * 2); // if text is another ref
<label>{{ shortText }}</label>
Vuejs templates allow for the use of JavaScript expressions.
<label>{{text.slice(0,5)}}</label>
To extract a portion of a string in JavaScript, you can utilize the String.prototype.slice() method
document.body.innerHTML = 'grab this part of the sentence'.slice(0, 8)<ng-switch on="MyData.Status"> <p ng-switch-when="2"> <p ng-if="MyData.SomeProp == false"> Message 1 </p> <p ng-if="MyData.SomeProp == true"> Message 2 </p> ...
